product overview
HBThe series of flashing alarms are widely used in industrial sectors such as petroleum, chemical, metallurgical, power, and light industry. It is a contact type sound and light alarm display instrument, which has the characteristics of simple circuit, few components, small size, strong anti-interference ability, high reliability, and simple wiring. The design of the instrument takes into account the trend towards computerization and multifunctionality, and adopts single-chip technology to make the instrument fully functional. It is a replacement product for the existing transistor flash alarm.
Product Features
1. Normally open or normally closed passive contacts, default normally open input, can be modified to normally closed input through software settings, without the need for jumper wires or circuit changes.
2. Use a red high brightness flat display tube for indication.
3. Equipped with testing and mute buttons, press the testing button, the indicator lights on the panel will light up in sequence, and the internal buzzer will sound synchronously with the status of the indicator lights. Press the mute button to release the testing status.
4. Detachable transparent face mask for easy replacement of workstation number labels and more flexible use.
5. The relay output can drive the audio alarm, and any alarm relay will close.
6. Output relay contact capacity (resistive load):AC 220V，2A；DC 24V，3A.
7. It can be manually muted. After manual muting, the audio alarm will be released, and the corresponding channel indicator light on the panel will remain on. After the fault is resolved, press the button to confirm and the indicator light will turn off.
8. Working conditions:
a） Environmental temperature:-10～+55℃
b） Relative humidity:20～90％RH（40At ℃)
c） There should be no corrosive gases in the surrounding air.
9. Working power supply:AC 95～265V，50/60Hz.
10. Power consumption: ≤5W.
11. Dimensions (width x height x depth):160×80×88(Hole size)152×76）
Main technical parameters
The alarm consists of a power circuit, a light-emitting device, an output driver, a microcontroller control circuit, and a software monitoring system. The alarm usually works in a monitoring state without any alarm signal input, and the lights and sound do not work. Once an external alarm arrives, the alarm will control the sound and light alarm to prompt on-site staff to solve the problem in a timely manner.
When a certain channel contact is activated, the corresponding channel's light flashes while the electric bell contact conducts and rings. Press the mute button to silence the audio alarm and stop flashing.
After the alarm signal disappears, the confirmed light alarm indicator will automatically reset.
When a certain channel contact is activated, the corresponding channel's light flashes and rings simultaneously. After the alarm signal disappears, the sound alarm will be silenced and the flashing will be extinguished.
When the test button is pressed, the eight lights of the alarm will flash and ring in sequence. When the test button is pressed again, the sound alarm will be silenced, the flashing will stop, and the alarm indicator will automatically reset.
