This allows the alarm to be used normally while testing. Remember you can use a shorting link at the terminals of the panel if you need to isolate any zones for testing purposes (e.g to test continuity of a loop) or to disable a zone. A third core is needed if multiple sensors are daisy chained together. The system can then differentiate between a no alarm condition, a tamper, or an alarm condition, using just 2 cores of cable for both contacts and tamper.

An EOL resistor is used at the last detector plus in addition a resistor across the contacts of each sensor in the loop. So if a burglar cuts a cable, this deactivates the tamper for all zones and potentially puts the system out of action until the break can be pinpointed.įully Supervised Loop wiring provides a separate tamper for each zone, so if a cable is cut or a loose connection occurs in the tamper circuit, only that zone will be out of action and also it's easier to trace the fault. The problem is that a global tamper is used and this loops through all the zones on the panel. Another disadvantage is that the specific sensor in the chain that triggered an alarm can't be narrowed down and only the zone can be identified.įully Supervised Loop (FSL) and Closed Circuit Loop (CSL) Wiringīasic alarm systems use 2 cores for sensors, 2 cores for tamper and 2 cores if needed for powering sensors. The disadvantage of daisy-chaining is that if one sensor develops a fault and contacts stay stuck open, the zone has to be omitted during arming, making the other sensors useless until the fault is rectified. O n a wired system, one or more sensors can be connected in series to each zone, known as "daisy-chaining". More sophisticated entry alarms for larger buildings will have a greater number of zones and the ability to identify activation of individual sensors, possibly indicating the sensor location on a computer screen mimic, depicting the floor plan of the building.

This zone has a delay associated with it before the sounder operates, allowing a password to be entered to disarm the panel. Entry/Exit ZonesĪn entry/exit zone is reserved for genuine entry to the building via a doorway. The user chooses the zones to be excluded as they arm the panel.

The program will generate an alarm if it thinks a sensor has been activated and an intruder has entered the building.

The user then interacts with the box via a remote wired or wireless keypad mounted on a wall.Ī microcontroller (which is a type of microprocessor) on the circuit board in the alarm panel/alarm box runs a software program which scans the sensors regularly.

All the electronics, backup power, connection terminals, autodialler/GSM modules are kept inside this box. A second advantage of this is that wiring can be hidden out of view and a smaller more discrete keypad can be mounted on a wall. Alternatively sensors may be wired or connect wirelessly to a box without a display or keypad, hidden away out of reach of burglars, so that it can't be tampered with.
