System Sensor CO1224T 12/24V, 6-Wire System-Monitored Carbon Monoxide Detector with RealTest Technology

Protect occupants and simplify system commissioning with the System Sensor CO1224T carbon monoxide detector — a system‑monitored CO solution built for security and life‑safety installations. The CO1224T pairs an accurate electrochemical sensing cell with RealTest® functional testing so technicians can confirm proper gas entry and meet NFPA 720 requirements quickly on site. Designed for integrators, it operates on 12/24 VDC and draws minimal current, allowing more devices per panel and reducing the need for extra power supplies. Built-in supervised wiring with SEMS terminals and a code‑required trouble/end‑of‑life relay provides clear status to alarm control panels and central monitoring stations, improving response and lowering false alarm service calls. UL 2075 listing and a 10‑year end‑of‑life timer make this detector a durable, code‑aware choice for residential and monitored commercial projects. Ideal for security systems, monitored fire alarm networks, and multi‑unit housing, the CO1224T delivers dependable CO detection and streamlined installation — add it to your next security or monitoring deployment for reliable, long‑term protection.
