CTM module wiring

The CTM City Tie Module is an interface between the control panel
notification appliance circuit and a master box. It provides off-
premises signal transmission for systems that must comply with
NFPA requirements for Auxiliary Protective Systems. The CTM
activates a local energy fire alarm box. For detailed information and
wiring, refer to the CTM Installation Sheet (P/N 3101025).
Requirements
When connecting a CTM to the panel, the following hardware and
programming requirements must be met:
• The NAC used must be dedicated to CTM use only
• All alarm zones must be programmed to activate the dedicated
NAC
• The NAC used must not be programmed for signal silence
