1 ABB STOTZ-KONTAKT GmbH ABB i-bus KNX Project planning of security systems STO/GM - Slide 1

2 Introduction Security systems are used to monitor objects against unauthorized intrusion as well as to protect persons against hold-up and technical hazards Security systems should call a security service or the police in case of emergency, therefore false alarms have to be avoided Normally false alarms are triggered because of bad project planning, wrong installation or incorrect operation of the customer Therefore the first requirement for a failure-free and effective security system is a detailed project planning STO/GM - Slide 2

3 First steps of project planning The complexity of a security system aligns to the objects exposure, the protected risk value and the security requirement of the customer First clarify the risks of intrusion with your customer and his insurance company Observe exactly the objects conditions and consider especially the constructural weaknesses Clarify with the customer if after the installation of the security system something of the constructural or ornamental conditions may change (cabinets, partitions, heaters, air-conditioning, curtains, etc.) Ask the customer about his wishes and behaviors (delayed arming, panic detector, local alarming, silent alarming, location of the components) STO/GM - Slide 3

4 First steps of project planning Doors Check the numbers and the material of the doors Colors of magnetic reed contacts Electromechanical bolt lock and/or lock bolt switching contacts Windows Check the numbers, material and type of the windows (how to open, size of the glass surface,...) Blocking bolt Glass break sensors Arming and disarming How and where will be the system armed (via code or key, external or internal arming) STO/GM - Slide 4

5 First steps of project planning Define the different detector zones (peripheral and interior protection zones, technical zones, panic attack, tamper zone, etc.) Consider areas, which should not be monitored at customers option. Make a note of this options. Define the wires run (please note: power lines, air ducts, cavity walls, etc.), length and numbers of conductors Control any unauthorized access options to the object (balconies, trees, garage roofs) STO/GM - Slide 5

6 Levels of surveillance according to EN Grade 1 Grade 2 Grade 3 Grade 4 Level Low risk Low to medium risk (private) Medium to high risk (commercial) High risk Perimeter doors Opening Opening Opening and penetration Opening and penetration Windows Opening Opening and penetration Opening and penetration Other openings Opening Opening and penetration Opening and penetration Walls Penetration Ceilings and roofs Penetration Floors Penetration Rooms/halls Trap Trap Trap Trap STO/GM - Slide 6

7 Peripheral monitoring What is monitored What is the monitored event What is used for monitoring Note Doors and windows Opening Magnetic reed contacts Drill hole or flush mounting in or on the window frames Glass break Glass break sensors Mounted on the glass surface Magnetic reed contact Glass break sensor Flush mounting Drill hole mounting Window frames Glass surface STO/GM - Slide 7

8 Interior monitoring What is monitored Rooms and halls What is the monitored event Detection of motion What is used for monitoring Motion detectors Note Observe sources of interference! Heating and air-conditioning (temperature differences) Mounting in room corners Do not mount in the direction of windows infrared det. dual det. STO/GM - Slide 8

9 Lock monitoring What is monitored What is the monitored event What is used for monitoring Note Doors Locking of the door Lock bolt switching contact Installation in the door strike plate Windows Closing of the window Blocking bolt Installation in the window surround Lock bolt switching contact Blocking bolt STO/GM - Slide 9

10 Setting/unsetting devices Setting/unsetting the System Delayed setting/unsetting Normal setting/unsetting (outside the building) What is used for setting/unsetting Panel SafeKey-Wallreader with/or without keypad Note Select delayed alarm detectors in the entry area Use an electromechanical bolt lock to prevent false alarms Panel Electromechanical bolt lock SafeKey-Wallreader STO/GM - Slide 10

11 Technical monitoring What is monitored Water leak Gas Leak Occurance of smoke Occurance of heat What is used for monitoring Water detector Gas detector Optical smoke detector Thermal maximum detector Note Observe installation location! (light and heavy gasses) Not in kitchen/bathroom/sauna For heat detection only smoke and heat det. optical thermal water det. gas det. STO/GM - Slide 11

12 Alarming Type of alarming Internal alarming with occupancy External alarming with absence Remote alarming (silent alarm) What is used for alarming Internal siren, keypad External siren with/without strobe light Dialling device with voice output Note Height at least 3m from the ground A/B cable acustic optical internal siren external siren STO/GM - Slide 12

13 Installation Material Junction boxes Cables Note near windows and doors to connect the sensors I-Y(ST) Y n x 0.6 or 0,8 mm, (Note: voltage drop using long cables) STO/GM - Slide 13

14 Example: residential building (1 area, setting/unsetting via external setting device) Electromechanical Bolt Lock Optical Smoke Detector Thermal Detector Display and operation STO/GM - Slide 14

15 Example: small shop (1 area) Optical Smoke Detector Thermal Detector Display and operation Electromechanical Bolt Lock STO/GM - Slide 16

16 Example: commercial building (3 areas) Optical Smoke Detector Thermal Detector Display and operation Electromechanical Bolt Lock STO/GM - Slide 17

17 Sources of false alarms Water pipes Heating, ventilation and air conditioning Suspended signs Light tubes Elektromagnetic immissions Pets, animals, insects Air turbulences Mobile devices, cargo goods Building structure, vibrations, Environmental conditions (Temperature, humidity) STO/GM - Slide 20

18 Various All components mounted within the supervised area Tamper contacts of outdoor devices (Siren, SafeKey) (Grade 2) Tamper contacts of all devices (Grade 3 & 4) Resetting a tamper alarm only for engineer (Access Level 3) Max. 10 contacts per detector circuit Ground the screen of cables (only L240) Installation of cables within supervised area Overvoltage protection Panel and dialler within the area of a detector STO/GM - Slide 21

19 Delivery to the customer A full demonstration of the alarm system should be provided including the operation of detectors, the use of hold-up devices and how these should be tested Clear and concise operating instructions should be provided It is recommended that alarm system is tested for a period to be agreed with the client. During this period the system should be operated normally but without alarm-devices Maintenance/inspection/repair The customer should sign an acceptance certificate stating the system has been installed in accordance with the document and operates accordingly System record/logbook STO/GM - Slide 22
