CH-XS fire machinery emergency start device
Short Description:
With the rapid development of cities, various types of buildings are increasing, and a large amount of flammable materials are being used. In addition, people's awareness of fire prevention is not strong, which greatly increases the possibility of fires. Although each building is currently equipped with a fire extinguishing system, it is also prone to electrical circuit failures, making it impossible to extinguish fires and endangering the safety of people's lives and property.

Overview:
With the rapid development of cities, various types of buildings are increasing, and a large amount of flammable materials are being used. In addition, people's awareness of fire prevention is not strong, which greatly increases the possibility of fires. Although each building is currently equipped with a fire extinguishing system, it is also prone to electrical circuit failures, making it impossible to extinguish fires and endangering the safety of people's lives and property. To solve these fire safety problems, our company has developed an emergency start (forced start) device for fire machinery based on the above issues. This switch can be manually operated to forcibly start the fire pump when the distribution cabinet cannot automatically start the fire pump in the event of a fire, so that the fire pump can operate effectively and avoid causing significant property losses to the people.
Usage environment:
·The ambient air temperature is between -5 ° C and+40 ° C, and the 24-hour average value does not exceed+35 ° C;
Altitude: not exceeding 2000m;
·Relative humidity: not exceeding 50% at+40C, the average lowest temperature in the wettest month does not exceed+25 ° C, and the average maximum relative humidity in that month does not exceed 90%, taking into account condensation on the surface of the product due to temperature changes.
Pollution level: Level 3;
Do not install in environments containing explosive gases, as there is a risk of explosion; Do not install in particularly humid places;
Do not install in a location where the external magnetic field is greater than 5 times the geomagnetic field, otherwise the circuit breaker will not work properly; Do not install in areas with vibration greater than 5g;
Do not install in places where gas media can corrode metals and damage insulation.
Install:
insulation test
This switch has undergone insulation testing according to standard regulations before leaving the factory. If retesting is performed before installation, the steps are as follows:
(1) Use a 1000VDC megohmmeter (CM1-63 is a 500VDC megohmmeter).
(2) The insulation resistance should not be less than 20MQ.
(3) Between the contacts of the circuit breaker, between phases, and between phases and the casing (the casing is covered with metal foil).
If the user does not have a megohmmeter, a power frequency withstand voltage tester can be used as a substitute test. The measurement location should refer to the insulation testing method, and a voltage of 3000V/1min should be applied. Installation method
(1) Please install on flame-retardant materials such as metal;
(2) The switch should be installed vertically;
(3) Fix the switch body, bottom plate, and base onto the mounting plate.
