Ammonia gas alarm is indispensable for the enterprise security equipment, can is it can develop the biggest effect, construction of the wiring is correct is also very important, only the wiring is correct to make gas alarm to play the greatest role!
Ammonia gas alarm device with control peripheral devices (such as the exhaust fan, the safety valve) function, alarm and can output signal voltage, open and close the safety electromagnetic valve exhaust device, to leak after troubleshooting can press the mute button, the elimination of the alarm sound, press the reset button, safety valve, re entering the state monitoring. Each detector monitoring environment for 8-15 square meters, the user can according to the environment by monitoring area, choose different specifications, such as user excess can overlay application. The controller uses three core shielding wire and the detector is connected (Note: single core wire diameter not less than 0.75mm2 GB line), the shielding layer and the controller casing is connected and reliable grounding. When using the RVV cable, wear metal pipe and metal pipe and the casing after connected with reliable grounding.
Ammonia gas alarm device is suitable for gas, petroleum, chemical industry, on fire protection, metallurgy, mine and other hotel, using combustible gases and toxic gases existing places. The product can effectively avoid combustible gas leak caused by fire, explosion and poisoning casualty and property losses et al.
