The GE photoelectric smoke detector is an interchangable head and base detector with a light-scattering optical sensor that provides outstanding stability and excellent response to a wide range of fires. A pulsed infrared LED light source and a high-speed photodiode sensing element are housed in an omnidirectional sensing chamber which is protected by an insect screen. The chamber is not affected by ambient light. For easy cleaning, the detector features a field-re¬placeable optical chamber. GE 702RE smoke detector is the industry’s first conventional self-diagnostic detectors specifically designed for the demands of commercial and industrial environments. If the detector drifts out of its UL Listed sensitivity range or fails internal diagnostics, the alarm LED flashes once a second to indicate trouble. 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. The magnet test causes the LED to blink. The number of blink counts corresponds to a smoke detector sensitivity range. And, if they become dirty over time, the 702RE detectors automatically adjust the alarm threshold through built-in drift compensation.
