The Notifier FSL-751E analogue, addressable, low profile smoke sensor designed for use with NOTIFIER intelligent fire alarm control panels. Also, the unique design of this sensor uses an extremely bright, focused laser diode, with special lens and mirror optics. In addition, the light beam and algorithms, allow the system to differentiate between dust and smoke particles.
The Notifier FSL-751E incorporates a bright laser diode and integral lens that focuses the beam to a very small volume in the center of the smoke sensing chamber. Light continues though the chamber and passes in to a light trap. Additionally, light is reflected in to a unique cylindrical mirror and gathers this light and passes it on to a photo receiver.
Compared to smoke, dust particles are very large but well spaced. Dust is in constant motion though the concentrated sampling volume, coupled with the fact that samples are taken periodically. The dust particle produces large pulses for only a couple of samples.
