Introduction to the perimeter alarm system wiring diagram
[ Huaqiang Security Network News ] 
In this article, China Security Network Xiaobian wants to introduce the wiring diagram of the perimeter alarm system for everyone. I hope that everyone can help.
1. Explosion-proof sound and light alarm has 4 lines of red (+V), black (GND), yellow (light signal control end) and blue (sound signal control end).
2. Use a wrench to open the top cover of the explosion-proof junction box and connect it with the explosion-proof sound and light alarm, and adjust the angle.
3. Unscrew the plastic threading connector at the power inlet hole of the explosion-proof junction box, replace the gas alarm with an explosion-proof bobbin (purchased), thread the cable from the power inlet hole, and lock it with an explosion-proof bobbin.
4. AC220V power supply, first connect the power cable with the explosion-proof junction box power conversion board L and N, and then connect the light control terminal and the sound control terminal to the +V of the sound and light alarm, and then emit an audible and visual alarm signal.
5. DC power supply: first connect the power cable to the explosion-proof junction box terminal +V and GND. The gas alarm then connects the light control terminal and the sound control terminal to the +V of the sound and light alarm to emit sound and light. Alarm.
6. After checking the connection, lock the explosion-proof junction box cable sealing joint, and the gas alarm will screw the explosion-proof junction box to complete the wiring.
According to the wiring diagram of the sound and light alarm, there are the following points:
1. Connect the input controller terminal to the detector terminal;
2. The connection of the output terminal to the linkage device;
3. When the inductive device such as the exhaust fan meets the condition of 5A/220VAV or less, it can be directly connected to the output terminal, but the load device should be directly connected to the output terminal as much as possible. When the load device is larger than 5A/220VAV, the external transfer device must be connected. ;
5. The controller and detector should ensure reliable grounding;
6. When performing various installation operations, you need to power off first, otherwise the host may be burned out.
The above is an overview of the wiring diagram of the sound and light alarm. I hope that everyone can better use it in life, and hope that everyone can more accurately connect the sound and light alarm.
Stop Valves are closed by screwing a rubber gasket down onto a seat in the middle of the valve. Pros only use small versions that act as shutoff valves for fixtures such as sinks and toilets and outdoor sillcocks. Flow is inefficient because of the circuitous route the fluid (water, in most cases) has to follow. It's important to orient the valve in the right direction with the arrow (cast into the side of the valve) aligned with flow direction. That way, water flows against the bottom of the rubber gasket. If the valve is put in backward, the flow will force the gasket away from the top of the valve.
