2.2 Wiring

1. I/O Wiring
The two I/O terminals can be programmed as hard-wired zone inputs and/or PGM outputs. See programming section [013] Opt [1,2].
1a. Zone Wiring
Zones 1 - 32 are reserved for wireless zones. If programmed as zone inputs, I/O-
1 is zone 33 and I/O-2 is zone 34.
Zones can be wired for Normally Open (NO) contacts with single-end-of-line
resistors or Normally Closed (NC) contacts with single-end-of-line or double-
end-of-line resistors.
Observe the following guidelines.
• For UL/ULC listed installations use SEOL or DEOL only
• Use minimim 22AWG, maximum 18 AWG wire
• DO NOT use shielded wire
• Wire run resistance shall not exceed 100

• Programming section [133]-[134] opt.[14] selects Normally Closed or
Normally Open
• Programming section [133-[134] opt.[15] selects SEOL resistors
• Programming section [133]-[134] opt.[16] selects DEOL resistors
Zone Status - Loop Resistance/Loop Status (DEOL only)
• Fault - 0 (shorted wire/loop)(shorted wire to 4.5KOhm)
Ω
• Secure - 5,600 (contact closed)(4.5KOhm to 6.25KOhm)
Ω
• Violated - 11,200 (contact open)(13.5KOhm to open)
Ω
• Tamper - infinite (broken wire, open)(9KOhm to 13.5KOhm)
1b. Programmable Output (PGM) and Aux Wiring
I/O terminals configured as Programmable Outputs (PGMs) switch to ground
when activated by the alarm system. The PGMs are open collector outputs.
With a 45 mA load, the voltage measured at the PGM and Aux + shall be
approximately 8V with respect to ground. With a 25 mA load, the voltage mea-
sured shall be approximately 10V.
Connect the positive side of the device to the Aux+ terminal.
Connect the negative side of the device to the I/O terminal.
Each PGM can provide 50mA maximum output.
NOTE: The alarm system can provide 200mA maximum of AUX current for
PGMs, relays, LEDs etc.
The AUX output shall be used only for residential burglary applications.
