System Sensor COSMOD4W 4-Wire Smoke/CO Interface Module

The System Sensor COSMOD4W is the interface module for compatible four-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 control panel.

Key features

• Designed for COSMO-4W detectors and listed compatible four-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 smoke or CO detector and cannot operate as a standalone life-safety device. Use only the listed four-wire detector combinations; do not connect COSMO-2W devices. Panel zones, end-of-line supervision, power, reset operation and notification behavior must be engineered and tested as a complete system. Contact Avenger Security to confirm availability.
