The 449CST from GE Security is a 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 135F (57C), 50-foot rated, heat sensor is available with all "T" model detectors.The 449CSRH includes an isolated alarm output for heat and activates an internal non-latching sounder (local alarm) for smoke.
