Description

500N Series two-wire conventional photoelectric smoke detectors bring together trusted technology and a full line of features that meet the demands of both residential and commercial applications. The 500N offers sounders in two-wire applications, specifically to meet residential code requirements.

Interlogix is also proud to offer proven technology like CleanMe®, dust compensation, field replaceable optical chambers, and self-diagnostics. CleanMe® is only available on the 500N 2-wire models and will communicate with compatible FACPs when servicing is required.

500N Series detectors work on a light-scattering principle. A pulsed infrared light-emitting diode serves as the light source, and a high-speed photo diode as the sensing element. This design protects against nuisance alarms caused by dust, insects, RF interference, and ambient light.
