Ge security esl 521CRXT sentrol smoke detector 2 wire
The ESL 500 Series self-diagnostic, two wire photoelectric smoke detectors are the industry's first conventional direct-wire smoke detectors with analog features such as drift compensation, multi-criteria detection and remote maintenance/trouble reporting (CleanMe). The 500 Series continually monitor their own sensitivity and operational status, and provide a visual indication if they drift out of the sensitivity range or fail internal diagnostics. The 521 Series also can send a signal (CleanMe) to any compatible control panel, allowing the dealer/installer to schedule a service call and avoid a false alarm.
