GE Security GEC-429CST Self-Diagnostic Photoelectric 2-Wire Smoke Detector with Heat Sensor


Our Price : $44.00

Product Code: GEC-429CST


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. For related documents, The 429 series is easily cleaned by replacing the proprietary fieldreplaceable 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 135F (57C), 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.
