400-003 Non-Addressable CO (Carbon Monoxide) Detector with Sounder and Relay (NO/NC), 12/24V

The 400-003 is a high-sensitivity, non-addressable Carbon Monoxide (CO) detector designed for integration into fire detection and safety systems. The device utilizes an advanced semiconductor gas sensor, ensuring early detection of toxic gas and high immunity against false alarms.

This model (400-003) is a 4-wire system detector equipped with a built-in sounder (siren) and a relay output, allowing for the control of auxiliary devices (e.g., ventilation, shut-off valves) during an alarm. Its compact and low-profile design easily fits into any interior

Features:
- Reliable Protection: Effectively detects dangerous concentrations of Carbon Monoxide (CO).
- Universal Compatibility: Works with 4-wire non-addressable and addressable (via zone monitor module) systems.
-Autonomous Functions: Features a built-in 85 dB sounder and a relay output (NO/NC).
- Easy Operation: Requires no sensor calibration or replacement; features an Auto-reset function when gas levels decrease
- Compliance with Standards: Certified according to UL 2075 and EN 50291 standards.
