UTC Interlogix (Formerly GE Security/ESL) 521NCSXT 2-Wire Photoelectric Smoke Detector, CleanMe, Sounder


  • Also known as: ES-521NCSXT, GES-521NCSXT

    • The UTC 521NCSXT self-diagnostic, 2-wire smoke detector is a conventional, direct-wire smoke detector with analog features such as remote maintenance/trouble reporting (CleanMe), drift compensation, and multi-criteria detection.

    The 521NCSXT continually monitors its own sensitivity and operational status, and provides a visual and remote trouble condition if the unit drifts out of the sensitivity range or fail internal diagnostics.

    The 521 NCSXT is equipped with both a rate-of-rise and fixed temperature sensor, a temporal 3 sounder and operates on 8.5 - 33 VDC.    		Features:
    • 2-wire
    • Photoelectric
    • Built-in sounder
    • CleanMe remote maintenance reporting reduces false alarms
    • Smart dual fixed/rate of rise heat works with photo chamber to catch fires faster
    • Built-in drift compensation reduces false alarms
    • Field replaceable optical chamber makes servicing a snap
    • Small, low profile design blends in with any environment
