4 3 INSTALLATION 31 Introduction There are basically three aspects to installing the AutoDial unit: wiring up the connections (see Section 3) powering-up the AutoDial unit (see Section 4) programming the AutoDial unit (see Section 5) Note: that these do not have to be done in this order. It is possible to do most of the programing before you arrive on site since the AutoDial will retain these settings in memory without being connected to mains power. 3.2 Wiring Connections Refer to the diagrams in Section 2.

6 3.3 Cabling Recommendations Signal Wiring: Use 0.25 mm 2 wire or better Avoid running wires close to other cables (especially mains or high-voltage wiring) In noisy environments or when running long distances use shielded cable. Note: when using shielded cable it is essential that: the shield is connected to the chassis of the AutoDial the shield is not connected to anything else. Telephone Cabling: Use proper telephone cable Avoid running wires close to other cables (especially mains or high-voltage wiring) 3.4 Multiple AutoDials On One Telephone Line We recommend that each AutoDial is connected to its own telephone line (or its own extension on the building s internal PABX phone system). This gives maximum safety for trapped people - especially during a mains power outage when many lifts may fail together. It is possible to connect as many as four AutoDial s to the same telephone line, but only if the line is near-perfect, and only if you do not want to phone into one of the AutoDials from outside. If the telephone line is not perfect then problems may arise, and for that reason we do not recommend this practice. Such a system will work on a first-come-first-served basis (i.e. the people who press the emergency push button first will get their call through, while all other AutoDials will remain silent). If only one telephone line is available for the AutoDials then we recommend a small PABX be installed. Note that such a PABX should have the correct telephone approvals, direct-dial capability and a backup battery. 3.5 Local Phone The AutoDial has provision for connecting a Local Phone. This allows easy communication between lift passengers and the lift engineer who has arrived to repair the lift. This is done by: mounting a phone (without keypad) in a convenient place (e.g. control room or machine room). connecting this phone to terminals 3 and 4 of the AutoDial terminal block. enabling the local phone function in the programming. See Section 5.6 (f) Pick-up Delay for Local Phone. When the handle is lifted on the local phone it will quickly establish direct contact to the passengers in the lift. A loud beep from the AutoDial speaker will automatically draw the passengers attention to this. Note: The Local Phone can not be used to contact the alarm receiving station. The Local Phone conversation will be overridden by an emergency call or by a call to the AutoDial unit. 6

7 4 POWER-UP 4.1 General When powered up by the 230VAC main power the AutoDial emits a loud sound from the loudspeaker. Note: If the unit has been programmed for Background Verification calls then it will immediately attempt to make a background call in order to synchronise its internal clock with the PC. Do nothing until all the tones have stopped. See Section 5.8 (c) Background Verification Calls. Do not touch the Reset push button while powering up the AutoDial since this may cause a Master Reset and all programming will be lost. The Emergency pushbutton must not be activated while powering up the AutoDial. 4.2 Installation Testing It is recommended that you always test an installation once it is completed. Two tests are importanta configuration test and a test call. Configuration Test (1 Beep Test): This test checks the microphone and speaker, and what the normal state of the switches is (normally-open or normally-closed). The test is performed as follows: Press the Reset button for one beep (and one beep only). The AutoDial will generate tones from the speaker which it will check with the microphone. Three beeps indicates that the test was successful. If the 3 beeps do not occur then it could be that the microphone is placed too far away from the loudspeaker. Next the AutoDial will examines the emergency buttons to see whether they are "normally open"or "normally closed" type. It will assume they are presently in the normal state and will adjust itself accordingly. Note: it is therefore important that none of these switches are active at the time of the test being performed. Test Call: It is recommended that a test call also be made to check the installation. This can be done in one of three ways: press the emergency button press the Reset button for two beeps (and two beeps only) exit programming mode using the * * # command The first two methods will dial the phone numbers in their normal order of priority. The final method will dial the phone number which was last entered or viewed during programming. This is useful because it allows a test call to be made to a specific phone (e.g. your own mobile phone). 7

8 4.3 Powering Down The AutoDial When mains power is removed from the AutoDial it will automatically switch to battery power. If you wish to switch the battery off so that you remove all power from the AutoDial then you must use one of the following methods: remove the mains supply and then hold the Reset button until the green control LED is no longer lit (usually after 3 beeps) remove the mains lead and then remove and replace the battery fuse. Powering down the AutoDial is recommended if the unit is being installed at a later date since it saves the battery being depleted. All programming will be kept because it is stored in non-volatile memory. Note: the speech message may be lost if you have an early type of speech module installed. 8

9 5 PROGRAMMING 5.1 Master Reset A Master Reset can be used to clear all programming. The procedure is as follows: Remove mains power from the AutoDial Press the reset button for 3 beeps to disconnect the battery (See Section 4.3 Powering Down the AutoDial) Hold down the reset button while reconnecting mains power (230VAC). Note: the reset button must be held until the AutoDial has finished the loud tone. 5.2 Methods of Programming The Auto-Dial may be programmed many different ways: using a touch-tone phone (locally or remotely) using the TeleTerminal (locally or remotely) using a PC and DTMF modem (locally or remotely) It is also possible to program the AutoDial in the office before going on site. All the programming is stored in non-volatile memory meaning it is retained even when disconnected from mains and battery power. Note: the speech message may be lost if you have an early type of speech module installed. Using an Ordinary Phone: This is a simple and convenient method for programming the AutoDial. However it does not allow you to check the AutoDial programming since there is no display to show the results of view commands. Note: even phones which have displays can not show the results of a view command. Local Programming: connect the phone to terminals 3 and 4 on the AutoDial s terminal block, or to the RJ 11 connector (using an adapter available from your supplier) enter programming mode (see Section Entering Programming Mode ). Remote Programming: dial the AutoDial from the phone (see Section Dialling into the AutoDial ) Using a TeleTerminal: This is a preferred way of programming the AutoDial since you can check your programming using the view commands However it can not be used to program the speech message. Local Programming: connect the TeleTerminal to the RJ-11 connector (using the cable provided with the TeleTerminal) enter programming mode (see Section Entering Programming Mode ) Remote Programming: connect the TeleTerminal to a phone socket using a standard modem cable (RJ-11 to local phone plug) dial the AutoDial from the TeleTerminal (see Section Dialling into the AutoDial ) Using a PC and DTMF modem: This information is provided with the PC software and DTMF modem. 9

10 5.3 Entering Programming Mode Once you have a programming terminal connected (TeleTerminal or ordinary phone) you can begin programming. To enter programming mode: Press and hold the RESET button for three beeps. If you are using a TeleTerminal: push the on-line button on the TeleTerminal you will hear a series of beeps from the TeleTerminal and a series of characters displayed. If you are using an Ordinary Phone: pick up the phone you will hear a series of beeps in the ear-piece Confirm the connection by pressing the # key. The beeps will stop. Note: if you do not press the # key within 60 seconds then the AutoDial will exit programming mode. If an access code has been programmed then this must be entered before any programming changes can be made. Enter the access code and press #. A correct code is indicated by 3 beeps. Note: if no key is pressed for 50 seconds then the AutoDial will begin beeping again. If the # key is not then pressed within 10 seconds then the AutoDial will exit programming mode. 5.4 Exiting Programming Mode When you have finished programming there are a number of methods for exiting program mode. Using the Exit Command: You can exit program mode by using one of the exit commands: * # exit program mode * * # exit program mode, and make a test call. If the * * # command is used then a test call is made to the phone number last changed or viewed. This is useful because it allows a test call to be made to a specific phone (e.g. your own mobile phone). Timing Out: If not key is pressed for 60 seconds then the AutoDial will automatically exit from programming mode. The AutoDial will beep for the last 10 seconds of this 60 second period to indicate that it is about to exit programming mode. Using the Reset Button: You can exit program mode by pressing the reset button. Powering Down The AutoDial: You can exit program mode by powering the unit down completely. See Section 4.3 ( Powering down the AutoDial ). 10

These allows the data programmed into the AutoDial to be viewed on a TeleTerminal screen. In general the view commands are simply the first part of the programming command. For example: * 1 # view phone number 1 * * 1 # view delay time for emergency push button 1 For more information see the individual command tables for each programming option. 11

12 5.6 Programming Options - General (a) Access Code: Command * 9 <access code> # * 9 # Function Program Access code View Access code The access code acts as a password to prevent unauthorised access to programming. Once an access code has been programmed it must be used to gain access to programming mode. The access code may only be cancelled through a Master Reset. The access-code can consist of 1 to 4 digits but must only contain numbers. 12

13 (b) Telephone Numbers: Command Function * 1 <phone number> # * 2 <phone number> # * 3 <phone number> # * 4 <phone number> # * 1 <phone number> * * 0 # * 2 <phone number> * * 0 # * 3 <phone number> * * 0 # * 4 <phone number> * * 0 # * 1 <phone number> * * 1 # * 2 <phone number> * * 1 # * 3 <phone number> * * 1 # * 4 <phone number> * * 1 # * 1 # * 2 # * 3 # * 4 # * 1 * # * 2 * # * 3 * # * 4 * # Program phone number 1 normal phone Program phone number 2 normal phone Program phone number 3 normal phone Program phone number 4 normal phone Program phone number 1 normal phone (no confirmation) Program phone number 2 normal phone (no confirmation) Program phone number 3 normal phone (no confirmation) Program phone number 4 normal phone (no confirmation) Program phone number 1 PC - TeleTech+ Protocol Program phone number 2 PC - TeleTech+ Protocol Program phone number 3 PC - TeleTech+ Protocol Program phone number 4 PC - TeleTech+ Protocol View phone number 1 View phone number 2 View phone number 3 View phone number 4 Delete phone number 1 Delete phone number 2 Delete phone number 3 Delete phone number 4 The AutoDial will automatically dial up to 4 different telephone number in order. The later numbers will only be dialled if the first numbers are not answered correctly. Dial Tone Checking Normally the AutoDial checks for a dial-tone before dialling. If desired the AutoDial can dial without checking for a dial-tone by making the first digit of the phone number a *. For example: * 2 * <telephone number> # If the AutoDial is connected to an internal phone system then it may need to dial an outside line prefix (e.g. 0 ) and then wait for a dial tone before dialling the actual telephone number. This can be achieved by putting a * between the prefix and the actual telephone number. For example: * 2 <outside line prefix> * <telephone number> # No Confirmation The AutoDial can be programmed with No Confirmation phone numbers. This is done by adding * * 0 to the end of the phone number. The difference in operation between No Confirmation numbers and standard numbers is described in Section 6.1 Alarm Calls to an Ordinary Phone. Note: we recommend programming all phone numbers as standard numbers rather than as No Confirmation numbers. Be sure you have read and understood Section 6.1 before deciding to use a No Confirmation number. PC Protocols If the AutoDial is being used to communicate with PC software at an alarm receiving station then the appropriate protocol must be selected. If you are using our PC software then you should press * * 1 after the phone number ( TeleTech+ protocol). Other PC protocols are available but these require a special order. Contact your supplier for details of these protocols. 13

14 (c) Emergency Pushbuttons Command * * 1 * T # * * 5 * T # * * 6 * T # * * 1 # * * 5 # * * 6 # Function Program Delay Time Emergency Push Button 1 (T = 1 99 seconds, 0 = disabled, Default = 5.) Program Delay Time Emergency Push Button 2 (T = 1 99 seconds, 0 = disabled, Default = 0.) Program Delay Time Emergency Push Button on unit (T = 1 99 seconds, 0 = disabled, Default = 1.) View Delay Time Emergency Push Button 1 View Delay Time Emergency Push Button 2 View Delay Time Emergency Push Button on AutoDial These options control how long an emergency pushbutton must be held before an alarm is generated. Note: Switches may either be normally-open or normally-closed. This is configured during installation by doing a configuration test. See Section 4.2 ( Installation Testing ). The relay output for the alarm bell will switch on the bell as soon as the emergency push button has been pressed and stop as soon as the button is released. However an alarm will not be generated until the programmed delay is exceeded which is indicated by a loud tone from the AutoDial speaker. (d) Audio Output Level. Command * * * 0 N # * * * 0 # Function Program Audio Output level (N = 1 9, Default = 7.) View Audio Output level This option controls the volume of the speaker. The default level will normally be correct for an AutoDial installed on the roof of most lifts. If an external loudspeaker is used then the volume may need to be adjusted (e.g. in a stainless steel lift where echoing may require a lower speaker volume be used to prevent microphone distortion). (e) Pick-up Delay for AutoDial Command * 6 T # * 6 # Function Program Pick-up Delay (T = 1-9 rings, 0 = will not answer, Default = 1.) View Pick-up Delay The AutoDial may be called from outside. See Section 6.4 ( Dialling into the AutoDial ). This programming option selects the delay before the AutoDial answers such a call. 14

15 (f) Pick-Up Delay for Local Phone These commands are only relevant if a local phone (e.g. in the machine room) is to be installed to allow a lift engineer to communicate with people trapped in the lift. Command * * 7 * T # * * 7 # Function Program Pick-up Delay for Local Phone (T = 1-99 seconds, 0 = disabled, Default = 0.) View Pick-up Delay This local phone should be connected to terminals 3 and 4 of the terminal block. The phone does not need a keypad. When the local phone is picked up there will be a delay before a connection is established (at which time the AutoDial will make a loud beep). This programming option determines how long that delay will be. 15

16 5.7 Programming Options - Speech Module (a) Speech Message Purpose The recorded speech message is important if PC communication is not used because it identifies which lift the emergency call is coming from. This is especially important if the trapped person cannot accurately describe their location (e.g. they are a visitor, are highly distressed or do not speak the same language as the person receiving the alarm call). The stored message will not be lost during main power failures due to the backup battery. For more information see Section 6.1 ( Alarm Calls to an Ordinary Phone ) (b) Recording the Speech Message These commands are only relevant when using a speech module. Command * 71 <speak> * 81 Function Record speech message Listen to speech message The TeleTerminal can not be used to record the speech message. You must connect a phone to terminals 3 and 4 of the terminal block or the outer terminals of the RJ-11 connector. You may also record a message remotely via the phone network, but the speech quality may suffer. The recording sequence starts immediately after the * 71 command has been typed. Speak loud and clear and without interruption. Avoid recording in an environment with background noise or lots of echoing (e.g. the lift shaft). If necessary use an extension lead to take the phone to a quiet environment. A pause in the speech exceeding more than 1 second is interpreted as "end of recording", and will be indicated by a short beep. Note: do not press the # key to terminate the message recording. Simply stop talking. Any tones recorded in the speech message may be misinterpreted by the AutoDial during play back causing unpredictable operation. If this happens then you must record the speech message again. 16

17 5.8 Programming Options - PC Receiving Software These commands are only relevant when using PC software at an alarm receiving station. For more information see the Alarm Receiver software manual. (a) ID code Command * 0 <ID Code> # * 0 # Function Program ID code for this unit Read ID code for this unit The ID code is a unique code which identifies which auto-dial unit is making the call. The ID code may be any number from 1 to 10 digits long. The ID code may be changed at any time, but can only be removed by performing a master reset. (b) Technical Alarm Inputs Command Function * * 2 * T # * * 3 * T # * * 4 * T # * * 2 # * * 3 # * * 4 # Program Delay Time Technical Alarm 1 ( Lift in Service ) (T = 1-99 minutes, 0 = disabled, Default = 0. Program Delay Time Technical Alarm 2 ( Door Open ) (T = 1-99 minutes, 0 = disabled, Default = 0. Program Delay Time Technical Alarm 3 (Free choice) (T = 1-99 seconds, 0 = disabled, Default = 0. View Delay Time Technical Alarm 1 ( Lift in Service ) View Delay Time Technical Alarm 2 ( Door Open ) View Delay Time Technical Alarm 3 (Free choice) They are used to indicate a fault has occurred with the lift. For example : the Lift In Service alarm signals that the lift has been in continual service longer than would be expected (e.g. it is stuck between floors) the Lift Door Open alarm signals that the doors have remained open for too long (e.g. someone has jammed them). Note: If the AutoDial is not programmed to work with PC software then any programmed technical alarms will still make call the programmed number and play the speech message. But: The AutoDial does not enter two-way communication when the receiver presses the # key (since the call was not triggered by someone in the lift) The AutoDial does not generate a warning/test tone when the receiver presses the 0 key There is no way that the receiver can identify which technical alarm is being signalled. When the Door Open input is active the emergency push-button will be disabled since the receiving station is already aware that the lift is faulty. This prevents nuisance alarms caused by someone pressing the emergency button and running away. If the Lift in Use input is used then the AutoDial will use this information to ensure that the Background Verification tests are not carried out while the lift is in use. This ensures that no one is in the lift who might be startled by the noises which these tests make. The Background Verification test will be delayed until one minute after the Lift in Use input has become inactive. 17

18 (c) Background Verification Calls Command * 5 <phone number> * * 1 # * 5 # * 5 * # Function Program phone number for Background Verification calls to PC (TeleTech+ protocol) View phone number for background verification Delete phone number for background verification The Background Verification call ensures that the installation is operating properly. Once a day the AutoDial will check: the battery condition the speaker and microphone (by generating tones from the speaker which it will check with the microphone). the telephone connection (by dialling the receiver software). Note: The time at which the call is made is set using the PC software. If an AutoDial fails to make a Background Verification call at the appropriate time then the PC software will alert the user to this fact (if configured to do so). The tests associated with a Background Verification call are not silent and may startle some one in the lift at the time. This can be avoided by using the In Service technical input See Section 5.8 (b) for more details. Once you have programmed the Background Verification telephone number into the AutoDial unit it is important to realise that no Background Calls will be made until the AutoDial has contacted the PC Alarm Receiver software and synchronised its own internal clock with that of the PC. Normally this would happen 6 hours later. However you can force the AutoDial to make the call immediately by powering the unit down completely (turn off the mains and remove the battery fuse) and then reconnecting the power. For more information see the Alarm Receiver software manual. 18

19 6 OPERATION 6.1 Alarm Calls to an Ordinary Phone (a) Standard Operation Note: this section assumes that no phone numbers are programmed to be no confirmation or PC protocol. When an emergency push-button is pushed for longer than the programmed time then the following happens: The AutoDial makes a loud tone in the loudspeaker (to acknowledge the alarm call). The AutoDial dials the first telephone number. If there is stored speech message then the AutoDial will being playing the stored speech message followed by 2 tones. Otherwise it will simply play the 2 tones at 1 second intervals. If the call is acknowledged by the receiver pressing the # key then the AutoDial will go into two-way speech communication. This ensures that the phone has been answered by an authorised and competent person (e.g. not by an answering machine) If the call is not acknowledged then after 60 seconds the AutoDial will hang up and dial the next phone on the list. During two-way communication the call receiver can speak freely to the person trapped in the lift. In addition certain commands are available to the call receiver by pressing keys on the touch-tone phone. See Section 6.2 ( Two-way Speech Commands ). After 180 seconds the AutoDial will time-out and automatically hang up. The AutoDial will beep for the last 10 seconds to indicate that it is about to do this. The time-out period can be restarted by simply pressing #. If a call times out then the AutoDial will assume there is something wrong at the receiving station and automatically dial the next phone number. When the call receiver has finally finished talking to the person trapped in the lift then they should terminate the connection by pressing *#. (If the call receiver does not do this but simply hangs up then the AutoDial will continue dialling phone numbers until it does get the correct acknowledgement and termination). (b) No Confirmation Operation In almost all circumstances the standard operation described in Section 6.1 (a) is the preferred method of dialling to an ordinary phone. This is because it ensures that the AutoDial will keep trying until authorised and competent help is reached. However there may be situations when the customer just wants a simple speech connection to one phone number (e.g. a hotel reception where training all staff to press # and * # is considered problematic) Such a situation can be covered by programming a phone number to be a No Confirmation number. A No-Confirmation phone number is different in two ways: The AutoDial immediately enters two-way communication when it dials (i.e. the receiver does not need to know to press # to talk to the person trapped in the lift) The AutoDial will not dial that number again if the correct confirmation is not received (i.e. the receiver does not need to know to press * # to stop the AutoDial calling them back again). A No Confirmation phone number is programmed by adding * * 0 to the end of the phone number during programming. See Section 5.6 (b) Telephone Numbers. 19

20 Notes: Since the AutoDial immediately enters two-way speech communication it does not ever play the speech message to the receiver and thereby identify the lift location. The receiver can still hear the speech message if they press 3 on their touch-tone phone (but of course the receiver must know that such an option is available to them) The call will automatically be terminated 3 minutes after dialling commenced unless the receiver presses a touch-tone key on their phone (whereby another 3 minutes is given). The AutoDial will beep for the last 10 seconds to indicate it is about to time-out. During two-way speech certain commands are available to the call receiver by pressing keys on the touch-tone phone. See Section 6.2 ( Two-way Speech Commands ). If a No Confirmation number is programmed then normally it would be the only phone number programmed into the AutoDial A call to a No-confirmation phone number can still be terminated using * # if desired. If such a confirmation is not received by the AutoDial and there are other numbers programmed then the AutoDial will continue to dial those other numbers in sequence until it does receive the proper termination sequence. But during that entire sequence it will never attempt to redial a No Confirmation number for a second time. A trapped person can redial a No Confirmation number (e.g. because there is no reply or the line is engaged) by waiting until the AutoDial has finished all attempts at dialling and by then pushing the emergency button to make a fresh emergency call. 6.2 Two-way Speech Commands During two-way speech the following commands are available to the call receiver by pressing keys on their touch-tone phone. Command # * N * # Function Warning tone. Loudspeaker on and microphone off. Microphone on and loudspeaker off. Play stored speech (if any) Microphone and loudspeaker on. Loudspeaker volume (where N = 1-9, 0 = default, default = see section 5.6 d) Terminate the connection. Pressing the 0 key generates a loud tone from the AutoDial speaker. This can be used as a warning tone. It also allows the operator to check that the speaker and microphone are operating correctly by verifyring that they can hear the tone in the phone ear-piece. (This may be useful if an alarm call is received but no one appears to be in the lift.) 20
