Circuit Descriptions and Wiring Details
MAIN CONTROL PCB (PCENV-M-5)
SINGLE ZONE HY-SPEC CARD (PCENV-1Z-5)
THREE ZONE BUDGET CARD (PCENV-3Z-5)
SNDR 1 & 2
2 conventional monitored sounder circuits, 28vdc reverse polarity monitored,
4K7 end of line. SNDR 1 can be selected to function as a “TWIN-WIRE” zone via
SW5 on DIL switches. Both circuits fused at 500mA. Maximum panel sounder
load 1 Amp.
ZONE 1
Conventional 2 wire zone with in built detector removal monitoring. Can be used
with zener diode type bases by via SW3 on DIL switches. Maximum detector
load 3mA. 4K7 EOL
MON I/P
Evacuate input, monitored for short and open circuit faults. Silenceable, non
latching. Requires 470 Ohms to activate. 4K7 EOL
OUTPUT FR / FLT
Switched –ve outputs, common fire and common fault. Maximum load 100mA
-VE INPUTS:-
SIL
Switched –ve input. When grounded provides remote silence alarms.
RES
Switched –ve input. When grounded provides remote reset.
P
Precinct or class change switched –ve input. When grounded activates sounder
circuits. Non latching, non silenceable
REM FLT
Clean c/o contacts, fail safe, unfused, maximum load 1 amp @ 50vdc
REM FIRE
Clean c/o contacts, unfused, maximum load 1 amp @ 50vdc
28v DC OUTPUT Fused 500mA 28vdc supply output for powering relays etc. Not recommended
for door retainer supply.
ZONE
Conventional 2 wire zone with in built detector removal monitoring. Can be used
with zener diode type bases via SW3 on DIL switches. Maximum detector load
3mA. 4K7 EOL
OPR
Switched –ve zone repeater output. Maximum load 100mA
SNDR
Conventional monitored sounder circuit, 28vdc reverse polarity monitored, 4K7
end of line. Can be selected to function as a “TWIN-WIRE” zone via SW5 on DIL
switches. Fused at 500mA. Maximum panel sounder load 1 Amp.
AUX RELAY
Clean c/o contact, fused @ 500mA. Common fire or zonal operation selection
via SW4 on DIL switches.
ZONES 1 – 3

used with zener diode type bases via SW3 on DIL switches. Maximum detector
load 3mA. 4K7 EOL
OPR
Switched –ve zone repeater output. Maximum load 100mA
ZP+
Common zone +ve for operation of 3 wire circuits. Maximum load 1amp @
28vdc
