System Sensor CO1224TR 28/11 and when two consecutive signalsThe CO1224 Series detectors are designed for system operation. These detectors are fully listed to UL 2075 (US models only) and CSA 6. 19 01 (Canada model only) and offer a code required trouble relay to send a sensor failure or end of life signal to the control panel and the central station. The CO1224 Series detectors also use SEMS type terminal Philips head screws for quicker and more positive wiring connections and code required wiring
