GE Security's 429CT is a UL listed 2-wire 12/24VDC Photoelectric Heat and Smoke Detector with dual fixed temperature and rate-of-rise heat sensor conditions. This smoke detector is the updated version of the ESL 425CT
The 429 series self-diagnostic, 2-wire smoke detectors continually monitor their own sensitivity and operational status, and provide a visual trouble indication if they drift out of sensitivity range or fail internal diagnostics.
The 429 series is easily cleaned by replacing the proprietary field replaceable optical chamber. All models are designed to reduce false alarms from dust, insects, RFI and external light.
An integral combination rate-of-rise and fixed 135 degreesF (57 degreesC), 50-foot rated, heat sensor is available with all "T" model detectors. An integrated silicon heat sensor and a dedicated microprocessor are used to detect heat and perform the rate of rise calculations.
The 429CT is a direct replacement for the 425CT. This detector is the one on the right (picture).
