Cap. 3 - Introduction to the operation 3 - Introduction to the operation The first part is aimed at fa mil iar is ing the user with the Sicep BiTech Sys tem. It will be fol lowed by a sec tion, which pro vides a de tailed anal y sis of the op er a tion of the unit. 3.1- The control panel Build ing on the many years of ex pe ri ence in the de sign and man u fac tur ing of ra dio sys tems, Sicep has now de signed an in no va tive antitheft con trol unit, fit ted with an en tirely bidirectional communication system, called BiTech. The use of state of the art tech nol o gies has re sulted in the pro duc tion of anti in tru sion prod ucts, which en able a con stant anal y sis of the sig nals from the in stalled ra dio de vices, and there fore a constant monitoring by the operating control station. This control unit incorporates a radio communicator which can be used for communication for pri vate use in the VHF or UHF range, for trans mit ting in for ma tion to sur veil lance con trol units. The main dis tin guish ing fea tures of the BiTech sys tem are: Mod u lar ity It in cludes 8 wired in puts and one 868MHz two-way disturbance resistant radio, with GFSK modulation, capable of handling Bi-directional communication with up to 32 wireless devices (keypads, ra dio con trolled sen sors, pas sive in fra red sen sors, mag netic con tacts etc.) and 4 REP signal repeaters. The Con trol unit can han dle up to 4 in de pend ent par ti tions, as well as zones shared by sev eral par ti tions. The 8 avail able out puts can be pro grammed in di vid u ally as: static, monostable and inverted. High level of se cu rity Should no con fir ma tion be re ceived by the Con trol Unit, all ra dio de vices can make sev eral attempts to communicate and ensure good transmission results. The tech nol ogy used en ables the con trol unit to de tect the pro longed ab sence of a ra dio de vice, with a pro gram ma ble time of 30 to 120 min utes, as well as fre quency jam ming at tempts, by con tin u ously mon i tor ing and gen er at ing an alarm, should pro longed dis tur bance oc cur (pro gram ma ble time 1 to 10 min utes). Safe com mu ni ca tion Com mu ni ca tions be tween the wire less de vice and the con trol unit are pos si ble thanks to a synchronised protocol with high speed dynamic encrypting. This synchronized technology ex change en ables dy namic two-way trans mis sions, ab sence of col li sions and an op ti mum dis tri bu tion of ra dio traf fic, as well as the pos si bil ity of ex tend ing the cov er age of the ra dio de vices with up to 4 re peat ers. Re duce con sump tion and speed of re ply Thanks to the Bi-di rec tional tech nol ogy, the sen sors re main in an sleep state when the sys tem is dis abled, and only trans mit the in for ma tion when re quired by the con trol unit. This re duces costs and at the same time in creases the du ra tion of the bat ter ies. The BiTech Con trol unit can ac ti vate all sen sors in just a few sec onds (ap prox i mately 4), en sur ing a prompt ness of sys tem re sponse, which can be com pared to stan dard wired sys tems.

The wired inputs can be used in balance mode and also in NC (Normally Close) / NA (Normally Open) modes. Double balanced mode enables distinguishing between Alarm and Sabotage (cable cut or short circuit). 3.5- Radio Communicator The con trol unit in cor po rates a VHF (156-174 MHz) or UHF (440-470 MHz) 10 watt trans ceiver, ac cord ing to the model. This trans ceiver is con fig ured as a fixed/mo bile equipment for pri vate use, there fore its use is de pend ent upon a Gen eral Authorisation is sued by the com pe tent authority. The trans ceiver can op er ate with the following protocols: - High speed MVS Sicep - 6-chan nel low speed Sicep, new/old for mat - Compatible 1 - Compatible 1 CRYPTO - Compatible 2, 8 channels - Compatible 2, 12 channels - Com pat i ble SIN 1, SIN 2, SIN 3 - Formats for crossing compatible REPs (5 protocols) In the pro gram ming phase, a trans mis sion chan nel must be as so ci ated to the events to trans mit. An ex cep tion is made for the high speed MVS Sicep pro to col when it is used with MVSNet con trol units. In this case, in for ma tion is trans mit ted in a sim i lar way to the tele phone Con tact-id and the con trol unit can trans mit all the events com pletely. A sec ond ary re serve fre quency is also avail able. When op er at ing on this fre quency, the con trol unit can use a pe riph eral code which differs from the main one. 3.6- Telephone Backup It is pos si ble to in stall an op tional tele phone card (IF-TL) in the con trol unit which al lows a back up tele phone trans mis sion to be sent when ever the ra dio trans mis sion is not successful. Two tele phone num bers are avail able. The con trol unit can also use sep a rate pe riph eral codes which differ according to the recipient. This card is also able to de tect if the line is cut and gen er ate a spe cific event at the end of a programmed time. 3.7- Wireless devices operation Each BiTech con trol unit has its own se rial num ber. This is univocally al lo cated dur ing man u fac tur ing, and can not be mod i fied. This num ber iden ti fies the sys tem and en sures that each sen sor will only work with the equip ment to which it has been as signed. The sen sors will be programmed automatically with a recording on the control unit itself, during the installation.

Cap. 5 - Operation: detailed description 5 - Operation: detailed description Let's now look at each func tion of the con trol unit in de tails. 5.1-4 Independent partitions- Zone sharing The BiTech con trol unit in cludes 4 par ti tions. If de layed sen sors are used, the Ad mis sion and Learning times must be es tab lished for each of them. These times will be the same for all sen sors of the same par ti tion. All par ti tions have an au to matic re arm ing func tion. This func tion can be ac ti vated by sim ply en ter ing a time dif fer ent from 0 in the "AutoArm T." box. Par ti tion 4 can be used for the Pa trol func tion The BiTech sys tem en ables the use and man age ment of zones shared by sev eral par ti tions. Let's see how they work by show ing some sim ple ex am ples. A S1 Partition 1 Zone 1 S3 Zone 3 C B Partition 2 P Two of fices A and B have a com mon C cor ri dor. To make things sim ple, this sys tem only in cludes 3 sen sors: one in of fice A, one in of fice B and one in the cor ri dor. The sys tem is there fore di vided in two par ti tions: par ti tion 1 (of fice A) and par ti tion 2 (of fice B); sen sor 1 (zone 1) only be longs to par ti tion A and sen sor 2 only be longs to par ti tion B, while sen sor 3 (zone 3) is shared and be longs both to par ti tions A and B. Each user (A and B) can only arm/dis arm their sec tion of the sys tem. Let's now sup pose that the start up con di tion is with both par ti tions dis armed. To sim plify things, all par ti tion are instantaneous and can be excluded. Case 1 - A user leaves and arms par ti tion 1 (to tal), in NON Mas ter mode. As zone 3 also be longs to a non armed par ti tion, zone 3 is not armed. Hav ing shared zones in a non ac ti vated state, par ti tion 1 re mains in the wait ing con di tion. In this way user B can cross the cor ri dor with out generating an alarm. - User B leaves and arms par ti tion 2 (to tal), in NON Mas ter mode. This will also arm zone 3. S2 Zone 2 NOTICE Note: If an in truder cause sen sor 3 to trip, both par ti tion 1 and par ti tion 2 will en ter an alarm con di tion. Case 2 - A user leaves and arms par ti tion 1 (to tal), in Mas ter mode. Al though also be long ing to a non armed par ti tion, zone 3 will also be ac ti vated. Par ti tion 2 en ters a wait ing state, be cause at least one of its zones is ac tive. Pag. 15

Cap. 5 - Operation: detailed description NOTICE Note: User B cross ing the cor ri dor will now gen er ate an alarm. This type of arm ing can be nec es sary when the Mas ter user (the su per vi sor) wants to en sure that all the sys tem is armed. Mas ter or non Mas ter arm ing mode de pends on the pass word used (dur ing the key pad op er a tions), or by the key used (op er a tion us ing an arm ing de vice) or by the re mote con trol. During the programming operations, each password, key and remote control are associated with an arm ing mode (Mas ter or nor mal). This as so ci a tion can only be changed dur ing pro gram ming. 5.2-24h Partition All the con trols that are al ways ac tive and ca pa ble of gen er at ing an alarm event, ir re spec tive of whether the par ti tions are armed or not, be long to the 24h par ti tion. These in clude: Zone/devices dis abling Wire devices sab o tage (cable cuts or short cir cuit for bal anced wired inputs). Bus485 devices tam per Wire less devices tam per Con trol Unit panel tam per (removal of cover and/or removal of con trol unit) Fire Panic Medical Con trol unit low bat tery level Wire less devices low bat tery level No power sup ply Wireless devices malfunction Bus485 devices loss Wire less devices jam ming Duress Wrong pass word entered Invalid key detec tion Tele phone Line fault Zone exclu sion Alarm zone Maintenance Antenna cut 24H zone alarm Pag. 16

Cap. 5 - Operation: detailed description 5.3- Automatic Rearming function All par ti tions can be au to mat i cally re armed af ter a settable amount of time. To en able this func tion the parameter "AutoArm T." on the page "Sys tem Par ti tions" needs to be set to a value other than 0. The re stor ing of an alarm mem ory from any par ti tion other than the Pa trol par ti tion will also de lete the Patrol partition memory. If dur ing au to matic re arm ing of an par ti tion, one or more of its zones are alarmed, the par ti tion will gen er ate a Bur glar Alarm event. WARN ING! The panel con trol works in dif fer ent way if you in sert the sys tem man u ally or au to mat i cally with im me di ate zones in alarm. ARM ING MAN UAL or dis arm ing by RE MOTE (MVSNet Cen tral Sta tion) - If there are im me di ate zones in alarm auto-ex cluded, the panel con trol de nied the arm ing; re peat ing the op er a tion the zone is ex cluded and the area is armed. The state of the zone is now de pend ent if pro grammed to self-in clude when it re turns at rest or be ex cluded un til the next arm ing. - If there are im me di ate zones in alarm and are not excludible, the panel con trol de nied the arm ing; even re peat ing the op er a tion the area can not be armed. AU TO MATIC ARM ING by time sched uler or area with time of arm ing. - If there are im me di ate zones in alarm self-ex cluded, the panel con trol forces the arm ing of the area ex clud ing au to mat i cally the zone. The state of the zone is now de pend ent if pro grammed to self-in clude when it re turns at rest or be ex cluded un til the next arm ing. - If there are im me di ate zones in alarm not excludible, the panel con trol arms the area and im me di ately starts the alarm, the zone is ac tive. 5.4- Patrol Partition function Par ti tion 4 can be ded i cated to the Pa trol func tion. This func tion is use ful when sup port from a Sur veil lance Unit for en vi ron men tal con trol is agreed. The se cu rity guard of the Unit can ac cess cer tain zones be long ing to this par ti tion. Once dis armed, par ti tion 4 will en able the Pa trol user (se cu rity guard) to carry out a pa trol ling of the par ti tion. Once this has been com pleted, par ti tion 4 can be ei ther man u ally re armed by the Pa trol user or au to mat i cally re armed af ter a set amount of time. In stan dard us age con di tion, the Pa trol par ti tion only has zones shared with other par ti tions and is al ways armed. This en sures that: - When the rest of the sys tem is dis armed, the Pa trol par ti tion is in a wait ing state. - Once the sys tem is armed, the Pa trol par ti tion be comes ac tive. - When the guard dis arms the Pa trol par ti tion for in spec tion, only the zones be long ing to the Pa trol par ti tion will be dis armed. Pag. 17

Cap. 5 - Operation: detailed description NOTICE Notes. - The Pa trol func tion can only be used af ter set ting a Re arm ing Time dif fer ent from zero. - If some of the shared zones are de layed, it may be come nec es sary that also this par ti tion is de layed. In this case, in put and out put times of the Pa trol par ti tion can be set equal to those of the shared zones. If the Pa trol func tion is not needed, set the Re arm ing Time to zero. By do ing, so the par ti tion will be have like any other par ti tions. 5.5- Scheduler The unit has a sched uler on a weekly ba sis with the fol low ing fea tures: Up to 4 pro grams each pro gram can be as so ci ated with one or more ar eas or one or more out puts each pro gram al lows n 2 on / off daily and/or n 2 ac ti va tion/de ac ti va tion of out puts associated Arming Total or Perimeter Management of day festival Up to 12 days of the fixed hol i days (pre-set) Up to 12 days of vari ables hol i days (pre-set) The programmation may be done by MVC or wired key pad (Ad min is tra tor menu). 5.6- Partitions Admission / Leaving times: Delayed zones The BiTech con trol unit de layed zones use the times pro grammed for the par ti tions they be long to. In other words, ad mis sion and leav ing times of de layed zones are the same that have been set for the par ti tion they be long to. A zone needs to be de layed if it needs alarm ing dur ing the par ti tion arm ing and dis arm ing operations. Example: if the key pad is placed on the en try cor ri dor and the door is fit ted with a mag netic con tact, once the sys tem has been armed the door will need open ing for the user to leave (leav ing time) and once the user re turns the door will have to be opened again (admission time). The two times op er ate as fol low: Leaving time: the delayed sen sors are ignored (they are not active). Admission time: delayed sen sors alarms are mem o rized and will only gen er ate an alarm when the time has expired. Due to its spe cial op er at ing pro ce dure, the Wire less mag netic sen sor will be dis cussed in de tails later on. Pag. 18

Cap. 5 - Operation: detailed description 5.7- Wired Inputs The BiTech Con trol Unit in cludes 8 wired in puts. These zones can be used for the con nec tion of sen sors us ing NC, NA or bal anced modes. NC Mode When this mode is set, the in put will be idle when short-cir cuited at the GND and in alarm con di tion when open. This ca ble con nec tion set-up is much sim pler, but it does not dis tin guish be tween a zone in alarm con di tion and a zone in sab o tage con di tion. NA Mode When this mode is set, the input will be idle when open and in alarm condition when short-circuited at the GND. Also this cabling set-up does not distinguish between a zone in alarm condition and a zone in sabotage condition. Bal anced mode (dual bal anc ing) In this mode, the in put is con nected so that it is ter mi nated, idle, at the GND by means of a 47KΩ re sis tance. The dif fer ent con di tions, based on the in put volt age, are listed in the ta ble be low. Input state: Voltage Cable-cut Sabotage: >2,7V Alarm: 1,8 2,7V Rest: 1,24 1,8V Alarm: 0,5 1,24V Cable shorted sabotage: < 0,5V For the ca bling pro ce dure re fer to the in stal la tion sec tion. Mode Not Used In this mode, the in put (zone) is al ways at rest and is not re ported as "zones Dis abled" on the keypad display. Alarm Mode 24H In this use the in put (zone) is al ways ac tive. The event gen er ated (Zone Alarm 24H) moves in the ac tive state when at least one zone is in alarm 24H. If this event is as so ci ated the ac ti va tion of an out put, this out put can be pro grammed as static or im pul sive; if it is static fol lows the plug (log i cal OR be tween in puts 24H), while if it is im pul sive it turns off af ter the programmed time. 5.8- Sensors block This fea ture al lows you to avoid false alarms caused by radio fre quen cy of the trans mit ter on the inputs. Checking the appropriate parameters for each input, every time the radio communicator is trans mit ting: - all variations of the input are ignored for the set time (Sensors Block Time, default 10 seconds); - BS out put (Block Sen sors) re mains ac tive for the du ra tion of that time. Pag. 19

Cap. 5 - Operation: detailed description 5.9- Zone exclusion - forced arming On some oc ca sions, upon arm ing of the sys tem it will also be nec es sary to ex clude an alarmed zone. Examples: - a faulty sensor remains in a permanently alarmed state (and the system needs arming, waiting for the replacement of the sensor); - dur ing the sum mer months, one may want to arm the sys tem, while keep ing a con tact protected window open. A forced arm ing is the arm ing of the sys tem when one or more zones are alarmed. The sys tem will no tify that one or more zones are alarmed, and the arm ing pro ce dure must be repeated. SPE CIAL CASES OF ARM ING WITH AN ALARMED ZONE SHARED BY MORE PAR TI TIONS: Delayed zone Non MAS TER arm ing of an PAR TI TION other than the last one: Dur ing the arm ing of the par ti tions it belongs to, the alarm con di tion is not noti fied and the zone is not acti vated. Non MAS TER arm ing of the last PAR TI TION: Dur ing the arm ing of the par ti tions it belongs to, the alarm con di tion is not noti fied but the zone is acti vated. Zone restore is required within the leav ing time. MAS TER arm ing of any par ti tion: Dur ing the arm ing of the par ti tions it belongs to, the alarm con di tion is not noti fied but the zone is acti vated. Zone restore is required within the leav ing time. Non de layed zone (that can or can not be ex cluded) Non MAS TER arm ing of an PAR TI TION other than the last one: When alarm ing one of the par ti tions the zone belongs to, the zone alarm con di tion is noti fied. The user is there fore obliged to con tinue with forced arm ing, even if the zone will not be excluded or acti vated. Non MAS TER arm ing of the last PAR TI TION: When alarm ing one of the par ti tions the zone belongs to, the zone alarm con di tion is noti fied. The user is there fore obliged to con tinue with forced arm ing and the zone will be excluded and acti vated. MAS TER arm ing of any PAR TI TION: When alarm ing the par ti tion the zone be longs to, the zone alarm con di tion is no ti fied. The user is there fore obliged to con tinue with forced arm ing and the zone will be ex cluded and activated. WARN ING! A de layed zone can not be ex cluded (a con trol sys tem pre vents ex clu sion). NOTICE Note. The bal anced zones that are in the state of Sab o tage are not con sid ered in alarm; is the same for the wire less sen sors. Each time a zone is ex cluded, the rel e vant event is gen er ated. Pag. 20

Cap. 5 - Operation: detailed description 5.10- Automatic re-including zones For the exclusion of a zone, since ver sion 1.0.4 you can choose the op er a tion of the area in 3 different ways: NO (not auto-dis abling zone) The zone is not excludible through forced arm ing. Single The zone excluded by a forced arm ing, remains excluded until the next arm ing. Auto The zone excluded by a forced arm ing, turns back active automatically when at rest state. All are valid only for wired in puts and for mag netic sen sors (Door and Aux sec tion). 5.11- Zone disabling The man ual ex clu sion of a zone (dis abling), is an op er a tion car ried out us ing the key pad or from the pro gram. It makes the zone permanently non ac tive. A dis abled zone can be re ac ti vated us ing the same pro ce dure. Each time a zone is ex cluded, the rel e vant event is gen er ated. For more de tails on zone dis abling re fer to the sec tion Key pad Op er a tions. 5.12- Outputs The BiTech con trol unit has 8 (expandible to 24) ground re ferred (GND) open col lec tor out puts, ca pa ble of driv ing up to 100mA. The out puts can be ei ther Static or monostable, de pend ing on their use. All out puts can be ac ti vated based on in ter nal states of the con trol unit, to no tify sys tem Events (re fer to the sec tion Events in the Pro gram ming chap ter), or can be used as re mote con trols ac ti vated by the Op er at ing Cen tre. This op er a tions can be car ried out also us ing a tele phone. Out puts not used to no tify sys tem events can be used for re mote con trol op er a tion and be en abled from the Op er at ing Con trol Station or by tele phone re mote con trol. In the lat ter case, only out puts 1 to 8 can be used. 5.13- Wireless sensors The BiTech control unit supports a special range of Wireless sensors and devices. This is a proprietary synchronized radio system with time division, that enables obtaining a continuous Bi-directional connection between the Control Unit and the devices. Brief op er a tion de scrip tion The BiTech sys tem is based on a Sicep pro pri etary pro to col. Com mu ni ca tions are in syn chro nized mode. This means that each de vice has its own time win dow, within a 2 sec onds cy cle, for com mu ni ca tion with the con trol unit. This brings spe cial ad van tages: im por tant sav ings on the bat tery, be cause each sen sor only ac ti vates the re ceiver (and trans mit ter) for a very short frac tion of the cy cle. real supervision of the sensors and sensor s intelligent operation. total freedom from collision, resulting in optimum utilisation of the radio channel. The BiTech sys tem sup ports up to 28 de vices (in clud ing sev eral types of sen sors, re mote con trols and keypads) and a max i mum of 4 re peat ers, which can be used to reach the sen sors and devices positioned in less favourable locations. Each Wire less sen sor (with the ex cep tion of the REP), is pow ered by a 3.6 V AA Lith ium bat tery. Pag. 21
