Mains Connections
The general requirements for mains wiring is described on page 5.
Do not connect the mains supply to the panel until you are fully conversant with the layout and features
of the equipment. A rating plate is fitted in the bottom left hand corner of the panel describing the nature
of the supply permitted.
The incoming mains supply should be brought into the panel in the bottom left hand corner, via the
knockout provided. A suitable cable gland must be used to secure the outer sheath of the cable used.
The earth must first be connected to the primary earth stud (peg) marked with a symbol using ring
crimp provided.
Sufficient earth lead should be left to allow Live and Neutral connections to be accidentally pulled from
terminal block, while leaving earth connection intact. Secondary earths may be connected to the brass
earthing block.

Circuit Descriptions and Wiring Details
MAIN CONTROL PCB (PCMINI4)
SNDR 1 & 2
2 conventional monitored sounder circuits, 28vdc reverse polarity monitored,
4K7 end of line. Both circuits fused at 500mA. Maximum panel sounder load 1
Amp.
ZONE 1 – 4
Conventional 2 wire zone with in built, schottky diode type, detector removal
monitoring. Can be used with zener diode type bases via SW3 on DIL switches.
Maximum detector load 3mA. 4K7 EOL
P
Precinct or class change switched –ve input. When grounded, activates sounder
circuits. Non latching, non silenceable
COMMON FLT
Clean c/o contacts, fail safe, unfused, maximum load 1 amp @ 50vdc
COMMON 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.
