The Notifier LPX-751L Laser Detectors provide a revolutionary advance in early warning smoke detection technology. The unique design of these detectors allows smoke detection sensitivity that is 10 to 50 times higher than present photoelectric technology. Because of this high sensitivity, the LPX-751L can provide a very early warning of slow smoldering fires. Its performance is comparable to present aspiration technology, at a substantially lower installed cost.

The Notifier LPX-751L uses an extremely bright laser diode, combined with special lens and mirror optics to achieve a signal-to-noise ratio that is much higher than traditional photoelectric sensors. In addition, the tightly focused light beam allows the system to differentiate between dust and smoke particles. Because of this differentiation, the Notifier LPX-751L can be set to extremely high sensitivity, yet can reject false signals caused by larger airborne particles such as dust, lint, and small insects. The Notifier LPX-751L is an intelligent (analog/addressable) detector as well as supports up to 99 LPX-751L detectors installed per AFP-200, AFP1010, or AM2020 loop.
