Wiring
Use four-conductor 1.2 mm to 0.8 mm (18 AWG to
22 AWG) cable. The maximum wire length of each sensor
loop is 305 m (1000 ft). The maximum multiplex bus wire
length per system is 610 m (2000 ft) if using 0.8 mm
(#22 AWG) wire or 1525 m (5000 ft) if using 1.0 mm
(#18 AWG) wire.
Keypads
No more than two keypads per 305 m (1000 ft) run with
a total of no more than 15 keypads in the system.

Lightning Suppression
MOVs and spark gaps provide suppression of lightning surges and static dis-
charges.
Outputs
The system provides three programmable outputs that can be controlled by
alarms, access control, ground start, smoke detector reset, or the control’s
arming state.
Alarm Output: Normally Open, 1.75 A contact con-
nected to auxiliary power.
Programmable Output 1: Solid state current sink (1 A maximum).
Can be used for alarm, arming state, or
access control.
Programmable Output 2: Solid state voltage source (500 mA
maximum). Can be used for alarm, arm-
ing state, or access control.
