Sounder Beacon
The sounder beacon is composed of DC24V, fire alarm circuit, LED light circuit and corresponding processing circuit. When fire occurs, the control panel gives out fire command. Then the sounder beacon gives alarm sound and LED flashes.

Product Features
  Built-in microprocessor.
  Adopt SMT process.
  Four cables, two of bus lines (non-polar) and two of power supply that are 24V and GND (non-polar).
  There is no special requirement for the cable used during construction, as long as the conductor cross-section area is not less than 1.0mm2.

Structure and Dimensions

1) After wiring construction, fix the base on the wall with 60mm mounting hole spacing.
2) Before installation, write address (1-200) to the device using encoder.
3) The loop is connected to terminal L1, L2 on the base; DC24V and GND are connected to the base V and G.
4) The sounder beacon should be installed after wiring inspection and before debugging to prevent losses caused by improper installation

Conduct alarm test regularly, recommended every six months.
