Product Description

ESL By Interlogix 500 Series conventional photoelectric smoke detectors come in a variety of models from the simplest to the most complex smoke and fire alarm applications. The 500 Series offers sounders in two- and four-wire applications, specifically to meet residential code requirements. For example, the 500 Series offers choices for optional auxiliary relays and isolated heat sensors for commercial applications, such as elevator recall or hotel/dorm rooms.

The 500 Series features innovations engineered specifically for the conventional fire system market, such as sensitivity drift compensation, field replaceable optical chamber, and self-diagnostics to continually monitor critical detector operations.

500 Series detectors work on the photoelectric light-scattering principle, a core technology pioneered by ESL in the 1960s. A pulsed infrared light-emitting diode serves as the light source, and a high-speed photodiode as the sensing element. This design has superior protection against nuisance alarms caused by dust, insects, RF interference, and ambient light, while providing the earliest warning to a non-specific fire type.
