SECTION 3 – ENGINEERING OPTIONS
General
The panel has various options which are programed by the selection of DIL switches on the PCBs. This
section explains which switch relates to which option.
PCENV-M-5 (Master PCB)
Switch Function when ‘off’ Function when ‘on’
1 Zone 1 latching Zone 1 non latching
2 Short circuit = fault, zone 1 Short circuit = fire, zone 1
3 Detector removal, standard Schottky diode
base
Zener diode head removal
4 Rem.fire relay, is common Rem fire relay, zone 1 only
5 Conventional operation (2 wire zone, 2
wire sounders)
Twin wire operation SNDR 1 (Two wires share
sounders and detectors)
6 Zone 1 operates all sounder circuits Zone 1 no sounder circuits, panel buzzer only
7 Zone 1 operates all aux relays Zone 1 does not operate Rem.fire aux, still
operates other aux relays
8 Sounder operation common Zone of origin continuous, other sounder circuits
pulsing (PCENV1Z-5 cards only)
