Below is information for convention fire alarm panels used by Fire Systems Ltd.
Detection zone wiring
The detection zones from our convention fire alarm panel, provide a nominal 24V DC to power the conventional fire detection. The fire alarm wiring is monitored for open and short circuit fault conditions by removing the 6K8 end of line monitoring resistors that are supplied fitted to the fire alarm control panels’ terminals and placing them across the last device that is wired to the zone circuit.
Fire detection zone circuits must be wired as a single, radial circuit with no spurs or T junctions to enable the monitoring circuit to work correctly.
On T series fire alarm panels, polarised sounders must also be wired across the detection zone but in reverse polarity to that shown by the zone terminals. At least one sounder should be fitted to each fire detection zone. Each zone can be configured individually as a 2-wire type zone or a non 2-wire type zone using configuration options C1 to C8.
For non 2-wire fire alarm system that are required to comply with BS5839 Part 1: 2002 detector removal requirements, detector bases fitted with a Schottky diode should be used and the end of line resistor replaced with an LCMU active end of line monitoring device.
