Description
 
  • Self-diagnostic, two-wire smoke detector
  • Provides remote maintenance/trouble reporting
  • Features drift compensation, and multi-criteria detection to reduce false alarms
  • Small, low profile design blends in with any environment

    The 521 Series continually monitor their own sensitivity and operational status, and provide a visual and remote trouble condition if they drift out of the sensitivity range or fail internal diagnostics.

    The 521 has a unique feature enabling it to send a signal (CleanMe) to the ESL 505 module (sold separately) when it has drifted outside of its UL Listed sensitivity range or has failed its internal diagnostics test
