Product Details
GE Security 4-Wire, Smoke Detector, End of Relay
The GGE449CTE is a self-diagnostic, four-wire smoke detector with an extra relay that provides two added functions: power supervision and sensitivity status. The 449CTE Supervisory relay is normally energized, and will trip with loss of power, providing power supervision. The relay also trips if the detector's self-diagnostics detect an electronic failure, or if the detector is outside the UL listed sensitivity range for more than one day. This results in a trouble condition at the control panel, providing early warning that the detector needs cleaning or maintenance. This meets NFPA 72 field sensitivity testing 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.
This series is easily cleaned by simply replacing ESL's 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 allows latching of the alarm for either smoke or heat.
