The 2-wire network photoelectric smoke detector needs to work with the fire alarm control panel together. From the product to the fire alarm control panel, there are only two wires transmitting the power signal and output signal. The product is powered via the fire alarm control panel. When the product detects the smoke and the smoke concentration comes to the alarm level, the internal circuit of the product generates the alarm current signal and sends the signal to the fire alarm control panel. The red LED indicator flashes also.
Our 2-wire network photoelectric smoke detector employs the digital circuit design, SMT production technology, and non-polar power input. With the supply voltage of 9V to 35V, it is compatible with all the conventional fire alarm control panels in the market. Meanwhile, the product is qualified with the LPCB EN54-7 certification.
