CPU Failure on WW Modem
The CPU Failure feature for WW Modem is available with main control module firmware version 4.3 or
greater.
Output 8 must be programmed as "System Fault" in System Outputs. Use the access control software outputs
or Simplified or Advanced (B000:00, System Outputs #56) keypad programming. For a negative to positive
output, it can be left defaulted. For a positive to negative output, it must also be programmed to be inverted.
Enable Line Failure on WW Modem
This feature is used to monitor for line faults from switched communicators such as REDCARE.
Note: The WW Modem must be plugged into the main control module.
• Simplified Configurations: Comms (Communications) Configure Group
- Enable Line Failure : Default: No (UK ACPO =

yes)
- Line Fail Polarity : Positive 12 VDC going to Negative 0V or Negative 0V going to Positive
12 VDC. Default: Positive
• Advanced Configurations: S005  03
- Field 2 : Parallel STU 8OP Supports Line Fail:

4 Wiring Specifications
• Module Bus (RS485) Cabling (device communication and power):
Recommended : 22 AWG, four (4) conductors, shielded twisted pair, 120 impedance, low capacitance,
41 pF / meter or 12.5 pF / foot (such as Belden 9842).
• Max. Length : Up to 610 m / 2000 ft. of cable on a Module bus port.
Note: For longer cable distances, and/or where many expansion modules are connected on one cable
(daisy chained, star wiring configurations are not acceptable) a 120

terminating resistor will
need to be installed across A and B communication terminals of the last module on the bus
cable.
• Modem/PC Link : Use kit provided, or 22/24 AWG low-cap cable (not reader cable). Shielded cable is
recommended.
RS485 (shared cable or modem): three (3) wires, see Module bus spec. above.
