The System Sensor CO1224T is a professional-grade, 6-wire carbon monoxide detector designed for seamless integration into 12/24Vdc fire and security systems. Engineered with electrochemical sensing technology, this unit provides high-accuracy detection of CO levels, ensuring code compliance with UL 2075 standards. A primary advantage for technicians is the RealTest technology, which permits functional gas testing using a canned CO agent, verifying the sensor’s response directly without the need for traditional, time-consuming methods. This detector features a low 20mA standby current draw, making it highly efficient for multi-device loops on restricted power supplies. The SEMS-type terminal screws facilitate rapid, secure wiring and supervision, while the integrated Form C trouble relay communicates sensor failure or end-of-life status to the control panel. Whether installed on a single-gang back box or surface-mounted, the CO1224T offers the rugged reliability required for commercial and residential life-safety applications. Key Benefits System Integration: Optimized for 12/24Vdc operation, compatible with most industry-standard alarm and fire panels. Simplified Testing: Patented RealTest feature allows for field-verification of gas entry using canned CO agents. Wiring Efficiency: SEMS terminals ensure positive contact and faster installation for high-volume contractor projects. Life Safety Monitoring: Onboard sounder providing 85dB Temporal 4 signal alongside dry contact relays for remote monitoring. Versatile Mounting: Low-profile design supports both wall and ceiling placement on standard single-gang electrical boxes. Common Questions Is the CO1224T compatible with residential security panels? Yes, as a 12/24Vdc 6-wire device, it integrates into most hardwired residential and commercial systems that utilize normally open or normally closed zones. How do I verify the device is actually sensing gas? Unlike standard test buttons that only check electronics, this unit's RealTest mode allows you to use a canned CO agent to confirm the electrochemical cell is functional. Does this unit require a separate power supply? Due to its low 20mA standby current draw, the CO1224T can typically be powered directly from the auxiliary power output of most control panels.
