SAFETY- SECURITY:
Smoke alarms that are properly installed & maintained, play a vital role in reducing fire deaths and injuries. Smoke alarms save lives. If there is a fire in your home, smoke spreads fast and you need smoke alarms to give you time to get out. Having a working smoke alarm cuts the chances of dying in a reported fire in half. Almost two-thirds of home fire deaths resulted from fires in homes with no smoke alarms or no working smoke alarms. We create the best products in Fire Safety industry, just give us your requirements and we will provide you quote at best prices.

This product is wireless smoke detector (hereinafter called detector), can be used for all kinds of anti-theft alarm system, used to detect smoke, when smoke concentration reached alarm standard, detector will alert immediately, meanwhile send alarm signal to alarm host thought wireless, so as to achieve the aim of anti-theft alarm
NFXI-OPT
The Opal photoelectric smoke detector has a completely new detection chamber design, the result of many years of research and development. This delivers improved responsiveness, reduced sensitivity changes caused by settling dust and reduced false alarms resulting from ingress of insect and other debris. The plug-in unit uses sophisticated processing circuitry that incorporates smoothing filters to help eliminate transient environmental noise conditions that can be the cause of unwanted alarms. The devices are managed by embedded software running complex algorithms that further improve resilience to false alarms and improve detection speed.

The Conventional Reflective Beam Detector has built in Laser beam pointing and Digital guide display for real
user friendly alignment method. The Laser beam pointing accurately point the exact location where to mount
mirror and with additional digital guide display allows to monitor and guide on the actual light intensity between
the mirror and detector which cannot be seen by our naked eye making it more easy and convenient in
alignment commissioning.
The beam detector has four adjustable operational range of between 8 to 20, 40, 70 and 100 meters beside
with three adjustable sensitivity setting ranges from 2.6dB to 4.8dB to meet the specific environmental
requirement. The detector works on the principle of reflective infrared beam obscuration. Used in conjunction
with a reflectors, it will notify the fire alarm panel when the infrared beam is obscured by smoke. Secure and
quick communication through the onboard processor enables the detector to make its own decision and drift
compensation resulting in greater automation.
The detector is ideal for use high ceiling and wide areas such as warehouses, large storages, shopping malls,
leisure centres, exhibition halls, hotel lobbies, printing houses, garment factories, museums and prisons, as well
as places where slight smoke particles or corrosive gas exist.
