The photoelectric type smoke detector, FMD-WT32L,is based on the photoelectric sensing principle to make up. When fire break out and smoke enters the light-tight box, the particles of smoke scatter the infrared light, and this scattered light goes into the receiving element, thereby emitting an electric current, and while the electric current is up to the fixed extent, the fire alarm will be activated.
The duo-colored LEDs are built in the main body in order to easily identify the current status of the detector. Green light blinks every 15 seconds to indicate that the detector is working normally. Red light shines continuously to confirm the fire alarm. This is an advance scientific device. It is very quick and accurate to activate the early fire warning system. Because of the pretty and compact styling, it is most suitable for the interior decoration of the modern buildings.
- With the photoelectric sensing principle, this kind of detectors is activated more quickly, accurately and reliably, and there are no false alarm due to chemicals, exhaust gas, wind and exterior light.
- The photoelectric type detector ensures repeated use and by removing the cover can accomplish maintenance easily.
- Duo-colored LEDs display separately; easy to identify the current status of the detector.
- Because of the compact styling and pretty outlines, it is most suitable for such modern buildings as employed in the design of decorative smooth ceilings.
- Using the 0.5mm bore diameter net can stop flying insects and dust particles easily, as well as make the inflow of smoke to go smoothly.
- No harm to humans and animals as no radiation source is used.
- Connection are non-polarized to avoid writing mistakes.
