Gas alarm installation precautions

Carbon monoxide (CO) gas is a colorless, odorless, non-irritating, toxic gas that cannot be sensed by five senses, and can inhibit the oxygen carrying capacity of blood. The toxicity of carbon monoxide mainly affects the supply and utilization of oxygen. The affinity of carbon monoxide and red blood cells is more than 300 times that of oxygen and red blood cells, resulting in hypoxia in human tissues.

Carbon monoxide gas alarm installation notes:

(1) There must be no strong electromagnetic fields (such as high-power motors and transformers) that affect the operation of the instrument around the alarm.

(2) The alarm is a safety instrument, sound and light display function, and it should be installed in the place where the staff can easily see and hear, so as to eliminate the hidden trouble in time.

(3) The installation height of the alarm should generally be 160-170cm so that the maintenance personnel can carry out routine maintenance.

(4) The alarm probe is mainly a detection element that contacts the combustion gas sensor. The platinum wire coil is coated with alumina and a binder to form a sphere. On the outer surface, platinum, palladium, and other rare metals are attached. Therefore, be careful when installing to avoid damaging the probe.

(5) The proportion of carbon monoxide is slightly lighter than that of air. The probe should be installed 30cm away from the ceiling and downward.

(6) Installation of open-air probes The installation height can be selected based on the density of the gas to be measured. It is especially important to note that the probes should be installed on the downwind side.

(7) The connection cable of the alarm circuit should be protected by a protective tube. It is best to add a metal hose at the connection of the probe, and pay attention to the explosion-proof grade of the factory.

(8) After installation and commissioning, be sure to install a breathable waterproof cover to prevent rain from entering the damaged probe.
