Detail: Wireless Smoke Detectors> Interconnection photoelectric wireless smoke detectors with Hush function CX-620PR

Model: CX-620PR
Brief Description
This product is a wireless interconnection photoelectric smoke
detector( hereinafter called detector) . It uses special structure design
and adopts MCU to analyze the photoelectric signal intelligently,
with functions of dustproof, mothproof, anti-light interference, etc.
therefore ensure the stability from designing. Meanwhile it also has
wireless interconnection and wireless network function for a variety
of environmental needs, improved users perception of alarm signal.
This product has good reaction on visible smoke caused by slow
smoldering or burning. It is suitable for fire protection in residential
houses, factories, shopping centers, hotels, office buildings, school
buildings, banks, libraries and warehouses, etc.

Interconnection photoelectric wireless smoke detectors with Hush function CX-620PR> Working principle

This product uses the principle that smoke particle can reflect infrared
light. The circuit is made up of infrared emission, receiver and MCU
processing parts. The infrared emission diode and receiver diode are
placed in the optical chamber, which can shield external light
interference but will not affect the smoke into it. Without smoke, the
receiver diode can receive very weak infrared light, when the smoke
enters into the chamber, due to the reflection, the received infrared
light increased. When the smoke attains the certain density, MCU
analyzes that it comes to alarm level, the alarm indicator will flash,
accompany with sharp alarm sound, meanwhile the detector will send
signals to other interconnected detectors and alarm host.
