Sound and light alarm wiring method

Audible and visual alarm (Audible and visual alarm), also called audible and visual alarm, is set to meet the special requirements of customers on the loudness of the alarm and the installation location. Both sound and light alarm signals are issued at the same time. Product specific areas: iron and steel metallurgy, telecommunications towers, hoisting machinery, construction machinery, ports, transportation, wind power, ocean-going ships and other industries; it is an accessory product in the industrial alarm system.

Sound and light alarm (also called sound and light siren) is an alarm signal device used in dangerous places to send warning signals to people through sound and various lights. Explosion-proof sound and light alarms are suitable for installation in explosive gas atmospheres containing IIC grade T6 temperature group. It can also be used in explosion-proof areas in areas 1 and 2 in the petroleum and chemical industries, as well as in the open air or outdoors. use. Non-coding type can be used with fire alarm controllers of any domestic and foreign manufacturers. When an emergency situation such as an accident or fire occurs at the production site, the control signal sent by the fire alarm controller activates the sound and light alarm circuit, and sends out sound and light alarm signals to complete the alarm purpose. It can also be used in conjunction with the manual alarm button to achieve simple sound and light alarm purposes. The alarm shell is made of stainless steel, the lamp shell has strong impact resistance, 180 clearly visible ultra-bright LED light-emitting tube, equipped with a super buzzer, stable work, long service life, low power consumption, and no pollution And the influence of water.

Wiring:

1. Connect the input controller terminal and the detector terminal correspondingly;

2. Connection between output terminal and linkage equipment;

3. When inductive devices such as exhaust fans meet the conditions of less than or equal to 5A/220VAV, they can be directly connected to the output terminal, but as far as possible, avoid the load device directly connected to the output terminal. When the load device is greater than 5A/220VAV, an external switching device must be connected ï¼›

5. The controller and detector should ensure reliable grounding;

6. When performing various installation operations, power off first, otherwise the host may be burned out.
