 Product Description
|
GE SECURITY SMOKE DETECTOR, PHOTOELECTRIC, 4-WIRE, HEAT SENSOR
CONTAINS RATE-OF-RISE HEAT SENSOR
The 449 series self-diagnostic, 4-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 449 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 135°F (57°C), 50-foot rated, heat sensor is available with all “T“ model detectors.
GE SECURITY SMOKE DETECTORS WITH CleanMe
The GE FX7 Series conventional self-diagnostic, smoke detectors, with CleanMe continually monitor their own sensitivity and operational status, and provide a trouble condition at the FireworX conventional control panel and FX detector if they drift out of sensitivity range or fail internal diagnostics. This meets NPFA 72 field sensitivity requirements without the need for external meters.
Additional diagnostic information is activated by applying a magnet near the detector's integral reed switch. This initiates a self-diagnostic routine and provides visual indication of sensitivity level, or if service is required.
If the 400 Series ever does require cleaning simply replace GE's patented 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, for earlier heat detection.
The 400 Series models allow latching of the alarm for either smoke or heat.
