External wiring
The external wiring should now be connected to the fire panel.
The fire panel is supplied with End Of Line Resistors for the zone and
sounder circuits, these must be transferred to the last device in the circuit.
The End Of Line Resistor must be replaced with Active End Of Line
device if removable smoke/heat detectors are used on the zone cirucit..
Please note these units are polarised.
1
DISCONNECT MAINS SUPPLY & BATTERY.
2
Connect the zone wiring, one zone at a time, transferring either the
End Of Line Resistor or Active End Of Line Device, if removable
smoke/heat detectors are being employed. The active end-of-line
devices are polarised and should be connected with Red/Orange
wire to the +ve and Black to the –ve.
3
Repeat the above procedure until all the required circuits are
connected.
4
Connect the sounder wiring one circuit at a time, transferring the end
of line resistor to the last sounder on that circuit.
5
Repeat the above procedures until all the required zones are
connected.
6
Connect other external circuits as required
7
Reinstate the mains supply, enter access code then press the
‘RESET’ button
8
Refit plastic facia. Do not over tighten two retaining screws.
