Sound and light alarms, also called sound and light alarms, are set up to meet customers' special requirements for alarm loudness and installation location. At the same time, sound and light alarm signals are issued. Product specific areas: Banking, government agencies, postal services, telecommunications, hotels, buildings, factory stores, shops, villas, ATMs, perimeter security systems and security service companies, etc.; is an accessory product in the fire fire automatic alarm system.
Once the sound and light alarm is installed in place, the location of the sound and light alarm will not be easily changed. The following points should be taken into account in the application.
(1) Find out which possible leakage points of the devices to be monitored, analyze their leakage pressure, direction and other factors, and draw the distribution map of the probes, and classify them into three grades I, II and III according to the severity of the leakage.
(2) Determine the direction of leakage of toxic gas when there is a large amount of leakage, based on specific factors such as the airflow direction and direction of the location.
(3) According to the density of leaked gas (greater than or less than air), combined with the trend of air flow, integrate the three-dimensional flow chart of leakage and make an initial set-point scheme at the downstream position of the flow.
(4) The leakage status of the leaking point was studied as microleakage or jetting. If it is a microleakage, set the position of the point to be near the leak. If it is a spray-like leak, keep it slightly away from the leak. Combine these conditions and draw up a final plan. In this way, the number and type of purchases needed can be estimated.
(5) For locations where there is a large leakage of toxic gases, a detection point should be set at a distance of 10-20 m per relevant regulations. For unattended, small, non-continuous pumping stations, attention should be paid to the possibility of toxic gas leakage, and a detector should generally be installed at the downtake.
(6) For locations with hydrogen leaks, the detector should be installed on the plane above the leak.
(7) For media with a gas density greater than air, the detector should be installed on the lower surface below the leak point and pay attention to the surrounding environment. For places where toxic gases can easily accumulate, special attention should be paid to the setting of safety monitoring points.
(8) For open toxic gas diffusion and escape environments, if there is a lack of good ventilation conditions, it is easy to make the toxic gas content in the air close to or reach the lower explosion concentration in a certain area. These are all non-negligible safety monitoring points. . According to the results of field accident analysis, more than half of them were caused by incorrect installation and calibration. Therefore, it is necessary to introduce the correct installation and calibration precautions to reduce the failure.
