429AT Self-Diagnostic Photoelectric 2-Wire Smoke Detector With Heat Sensor , 12/24 Vdc 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?F (57?C), 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. FEATURES: Intelligent self-diagnostics Field-replaceable optical chamber Low-profile design Plug-in terminal block Advanced false alarm immunity Meets NFPA 72 field sensitivity testing requirements without the need for external meters ?
