Description
 
The 500 series self-diagnostic, 2-wire smoke detectors are conventional direct-wire detectors with analog features including drift compensation, multi-criteria detection, and remote maintenance/trouble reporting (CleanMe). The detectors continually monitor their own sensitivity and operational status and provide a visual and remote trouble condition if they drift out of calibration range or fail internal diagnostics.
