Wireless Interconnected Photoelectric Smoke and Heat Detector (AC Power Supply)

The HM-620DHW-AC AC powered wireless interconnected photoelectric smoke and heat detector is outfitted with the receiving and transmitting modules. After being triggered to alarm, it would send the alarm signal to other products in the interconnection group to form the interconnection alarm.

Features
1. The plug-in type terminal block design at the bottom of the product enables easy and convenient wiring.
2. We guarantee the stability of the product from the design basis by adopting the unique structural design, and utilizing the MCU to process the photoelectric signal intelligently. The product shows advantage of dust prevention, pest immunity and light interference resistance, etc.
3. The wireless interconnected photoelectric smoke and heat detector also has the function of wireless interconnection. It is suitable for various installation environmental needs, and makes the user have stronger perception to the alarm signal.
4. The product is sensitive to the visible smoke generated by slow smoldering or the flame combustion. It is very applicable for fire alarm in residential area, shopping mall, factory building, office building, teaching building, bank, hotel, and more.

Working Principle
The product works on the principle of the particles in smoke refracting infrared light. The circuit mainly comprises the infrared transmitting part, receiving part and MCU processing part. The optical chamber, in which there is the transmitting tube and receiving tube, generates the shielding effect on the interference from the external stray light, but won't affect the smoke getting in.

When there is no smoke in the environment, only weak infrared light can get to the wireless interconnected photoelectric smoke and heat detector. When there is the smoke in the optical chamber, the scattering effect would strengthen the received optical signal. With the increase of the smoke concentration, once the MCU analyzes the smoke concentration reaching the alarm threshold, the product raises the alarm by emitting the harsh alarm sound and the LED indicator flashing. Meanwhile, it sends out the alarm signal to other interconnected products and alarm host.

Because the wireless interconnection range is 200m in open space, one wireless interconnected photoelectric smoke and heat detector giving the alarm would trigger all other interconnected products within the range to raise the alarm.
