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 replac- ing 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 1350F (570C), 50-foot rated, heat sensor is avail- able with all "T" model detectors (see selection guide), allowing latching of the alarm for either smoke or heat. The 449CSRH includes an isolated alarm output for heat and activates an internal non-latching sounder (local alarm) for smoke, making it ideal for motel/hotel and dormitory rooms where smoking is permitted. continued
