Installation considerations
(1) The alarm probe is mainly a detection element that is in contact with the combustion gas sensor. The platinum wire coil is coated with alumina and a binder to form a sphere. On the outer surface thereof, platinum, palladium, and other rare metals are attached. Therefore, be careful when installing to avoid damaging the probe.
(2) Toxic gas alarm The installation height of toxic gas concentration alarm should generally be 160-170cm to facilitate maintenance personnel to carry out routine maintenance.
(3) 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.
(4) There must be no strong electromagnetic fields (such as high-power motors and transformers) that affect the operation of the instrument around the alarm.
(5) The density of the gas to be measured is different, and the installation position of the indoor probe should also be different. When the measured gas density is less than the air density, the probe should be installed 30cm away from the roof and downward; otherwise, the probe should be installed 30cm away from the ground and upward.
Gas alarm gas concentration alarm gas leakage alarm wiring
1. Connect the input controller terminal with the detector terminal
2. Connection of output terminals and linkage devices
3. When the inductive equipment such as the exhaust fan meets the condition of less than or equal to 5A/220VAV,
4. Can be directly connected to the output terminal, but as far as possible to avoid the load device is directly connected to the output terminal, when the load device is greater than 5A/220VAV, external transfer equipment must be connected;
5. The controller and detector must ensure reliable grounding.
6. When performing various installation operations, it is necessary to turn off the power first, otherwise the host may be burned out.
