System Sensor COSMOD2W i4 Series 2-Wire Interface Module

System Sensor COSMOD2W 2-Wire Interface Module

Overview

The System Sensor COSMOD2W is a 2-wire interface module for fire alarm system signal conditioning and equipment integration in commercial and industrial fire detection architectures. Operating at 35VDC, the COSMOD2W translates control signals between fire detection equipment and panel systems in retrofit and new-build installations where 2-wire protocol interfaces are required. Compact form factor supports standard electrical enclosure mounting and field deployment without requiring dedicated power drops.

Compatibility

The COSMOD2W integrates into System Sensor i4 Series fire alarm system architectures and control panels requiring 2-wire signal conditioning. Designed for retrofit applications where existing detection equipment must communicate with legacy or conventional analog fire alarm control systems. Consult the specific fire alarm control panel documentation to confirm protocol compatibility before installation.

Installation Notes

Operating voltage is 35VDC — verify your fire alarm control panel supply voltage before wiring. Module is rated for panel mounting in standard electrical enclosures; secure with appropriate fasteners for vibration environments. Connect 2-wire signal inputs and outputs following terminal markings on the module housing. Environmental operating limits and temperature range are standard for indoor commercial fire alarm equipment — avoid moisture-prone locations unless the enclosure is rated for the environment. No external power supply is required; the module draws power directly from the panel's 35VDC supply line.
