Interface modules for intelligent fire detection and alarm systems
An analogue fire system is usually designed with a number of loops, each beginning and ending at the
fire panel. The integrity of loop wiring is vital for data transmission, where a short circuit between loop
wires would be very serious. Hence it is necessary to have isolating circuits positioned in the loop in
order to isolate any section containing a short circuit, until the fault is rectified.
The isolator detailed here is polarity sensitive and will normally switch out the negative arm of the loop, when a
short circuit is sensed.
Normally the isolator allows current flow in both directions. If the loop voltage falls beneath a preset threshold the
isolator will switch open to isolate the incoming and outgoing lines. The device will test the isolated section
regularly and will reconnect when the fault is cleared.
Isolating devices are provided either as standalone products or integral within many interfaces, detection or sounder
units. Interfaces with integral isolators and detectors fitted to isolating bases will stay operational when the adjacent
section of loop is isolated. The isolating unit, when isolating, will display a yellow fault indication LED.
It is good practice for devices wired between two isolators to be located in the same zone.
Zone monitor with isolator
FA95-ZMU
Powers a zone of up to 20 conventional detectors (Orbis or FAP6) from the
loop. The device sends a high analogue value to the panel, only when a
detector on the monitored circuit changes to an alarm state. Features:
●
Suitable for both Anatec FA95 and Discovery protocols
●
Surface mounting with entry points for cut out on sides and rear
●
Connections for loop in & out wiring and detector zone + & – inputs
