System Sensor COSMOD2W 2-Wire Smoke/CO Interface Module

The System Sensor COSMOD2W is the interface module for compatible two-wire i4 smoke and carbon-monoxide detectors. It interprets detector signals and provides separate smoke and CO outputs, with an optional trouble output, to a compatible alarm control panel.

Key features

• Designed for COSMO-2W detectors and listed compatible two-wire devices
• Separates smoke and CO alarm reporting
• Supports an optional trouble-reporting circuit
• Connects compatible detectors to two or three panel zones
• Supports up to 12 compatible detectors when installed within listed limits

Important compatibility notes

This module is not a detector and cannot operate as a standalone life-safety device. Use only listed two-wire detector and panel combinations; do not connect COSMO-4W devices. Zone compatibility, end-of-line resistance, current draw, reset operation and notification behavior must be engineered and tested as a complete system. Contact Avenger Security to confirm availability.
