Notes:
1. All wiring to be 18AWG minimum or to local
code.
2. Conductors must test free of all grounds.
3. Voltage input 18.9VDC min. to 32VDC max.
4. Maximum current is 75mA per output.
5. Drawing depicts typical wiring. All output
zones may not be wired. Supervision for the
unused inputs are by-passed in software.
6. Wiring is supervised and Power-Limited.
7. For N2 Comms wired in a “bus” fashion, the
maximum line distance is 4000 ft. For N2
Comms wired in a T-Tapped configuration,
the maximum distance to any N2 device is
2500 ft, with maximum total wire distance
not to exceed 10,000 ft on the T-tapped lines.
If the 24 Point I/O is the last device on the N2
bus (Non-T-Tapped), or the furthest device
(T-Tapped) terminate across N2+ and N2-
using a 733-974 (100
:
:
, 1/2W) resistor
harness.
8. Total current = 60mA base controller current.
Add current for each output used.
9. Wiring to I/O terminals must not be run with
AC wiring.

11. Allowable power supplies: 4010-9101, -9102,
-9201, -9202, -9813, and -9814 or any
regulated Power-Limited supply that is UL
Listed for Fire Protective Signal Use.
