System Sensor COSMO-2W Smoke and CO Detector

The System Sensor COSMO-2W is a commercial two wire carbon monoxide and smoke detector designed to provide reliable fire and carbon monoxide detection within a single device. It combines advanced photoelectric smoke sensing with an electrochemical carbon monoxide sensor to deliver comprehensive life safety protection while reducing installation costs and wiring requirements.

Part of the i4 Series, the COSMO-2W features an integrated sounder, automatic drift compensation, dual sensing technology, and a replaceable carbon monoxide sensing cell. Its plug in design simplifies installation and maintenance, making it suitable for a wide range of commercial and residential applications.

Product Functions

• Detects smoke using photoelectric sensing technology
• Detects carbon monoxide using an electrochemical sensor
• Activates an integrated audible sounder
• Reports smoke alarms to the fire alarm control panel
• Reports carbon monoxide alarms to the fire alarm control panel
• Performs automatic drift compensation
• Continuously monitors detector sensitivity
• Provides maintenance indication
• Supports loop testing
• Provides carbon monoxide end of life monitoring

Electrical & System Information

The COSMO-2W operates on a nominal 12 volt or 24 volt non polarized two wire circuit with an operating voltage range of 8.5 to 35 VDC. It incorporates automatic drift compensation and smoothing algorithms that continuously adjust smoke sensitivity for dependable long term performance.

The detector includes a built in sounder capable of producing Temporal 3 fire alarm signals and Temporal 4 carbon monoxide alarm signals. A replaceable electrochemical carbon monoxide sensing cell extends product service life while reducing replacement costs. Three LED indicators provide visual status for standby, smoke alarm, carbon monoxide alarm, maintenance, and end of life conditions.
