Optical Sensor Linear Detection System manufacturer, optical sensor relate, Optical sensor linear detector, optical sensor bracket
When a fire signal is received at the receiver by a detector or a transmitter, the receiver activates the alarm and displays a fire alarm in the boundary zone. The coupling is provided between the coupling of the motor shaft in the alarm box and the other end fixed to the tension spring, so that the motor rotates and the coupling reciprocates.
This reciprocating motion hits the inner wall of the alarm box and generates more than 90dB of sound. It is 125mm in outer diameter and has a small outer shape, so it can be easily installed in a fire hydrant.
