Product Description

Smoke Detector,2-Wire,Heat Sen: Home Improvement. The 521 Series self-diagnostic, two-wire smoke detectors are the industry's first conventional direct-wire smoke detectors with analog features such as remote maintenance/trouble reporting (CleanMe), drift compensation, and multi-criteria detection. This meets NFPA 72 field sensitivity testing requirements without the need for external meters. The 505 is an interface module that will signal a 24V panel via relays when the 521 is dirty. The 521 has a unique feature enabling it to send a signal (CleanMe) to the 505 module (sold separately) when it has drifted outside of its UL Listed sensitivity range or has failed its internal diagnostics test.
