Wire run distances are in feet / meters from the Aux. +/- terminals to the
End-Of-Line Power Supervisory Relay. Figures are based on 12 VDC at
the Aux +/- terminals with a maximum 10% voltage drop at the RM-1
relay.

The wiring table gives the wire run length from the control panel
to the keypad for various gauges of wire. Wire run lengths are
based on the maximum current drawn by the keypad. (All lights
ON).
If two wires of the same gauge are paralleled, the run length can
be doubled. eg. If 8 #22 AWG wires are used, 2 red, 2 blk, 2 grn
and 2 yel, the run length would go from 420’ to 840’ (127 to 254
m).
Burglary Zone Wiring
Burglary zone definition, (eg. Delay, Instant, 24 Hr. etc.) is
programmed via the keypad. See the Programming Guide,
Section [11].
Fire Zone Wiring
Any one of the 6 zones may be programmed as a Fire Loop. See
Programming Guide Section [11].
Smoke detectors should be the latching type and have N.O.
alarm initiating contacts. Power wiring from the AUX + /
PGM terminals should be supervised using an RM-1 relay
after the last smoke detector. The RM-1 N.O. contacts
(closed with power applied) should be wired in series with
the alarm initiating end-of-line resistor so that should power
to the detector(s) fail, a fire loop trouble will be initiated.
