Appendix C,
Remote Relay Modules
• Optional Remote Relay units:
• A total of four remote relay units may be added to the modbus
network.
• Modbus ID numbers of the remote relay modules must be
programmed for ID#30, 31, 32, or 33.
• Input Remote Relay on all remote units is the local silence
alarm.
• Closing this input will silence the local alarm as well as the
ModCon75 Alarm. Output O0 is for the local alarm output.
NOTE: If Zone Alarms are programmed as Latch, user can silence the
alarm at the remote relay, but the Zone alarm will not clear until
the unlatch input is initiated at the ModCon75 Controller.
