Fire Protection System Mutual Investment Function

Hangzhou JWG Technology Co.Ltd | Updated: Oct 11, 2017

Fire elevator control cabinet should be equipped with the first function of landing, Fire Protection System fire 24V contact terminal 2, forced landing after the first layer should be feedback signal passive contact terminal 2, a total of 4 contacts or configure a 24V DC relay.

Non-fire elevator control cabinet should be equipped with forced landing function 24V contact terminal 2, Fire Protection System forcing the first power, there should be power feedback signal passive contact terminals.

In addition to the fire shutter door control box to provide 24V control takeoff and landing contacts and feedback signal passive contact, the strong power outage, Fire Protection System the shutter door should also have a feedback signal, the feedback signal should be removed in the shutter door switch.

The control cabinet in the main pump can have in the control room linkage with 24V Kai, stop the pump contacts, and have feedback signal Kai, stop the point. Main and spare pump control cabinet with interlocking interchange function.

Pressure fan, exhaust fan, fan control cabinet should be 24V Kai, Fire Protection System stop contact, and a one-to-one feedback signal passive contact. Fan power with mutual investment function.

Welded steel pipe: Suitable for buried and overhead piping and fire sprinkler systems for fire hydrant systems and submerged and overhead piping for water spray systems for the delivery of low pressure fluids. According to the wall thickness can be divided into ordinary steel pipe and thickening. Fire Protection System According to the different process can be divided into ordinary welded steel pipe and hot dip galvanized welded steel pipe.

Seamless steel pipe: suitable for the main pipe or the lower part of the system working pressure higher parts of the pipeline. According to the different process can be divided into hot and cold rolling two.

When the outdoor fire for life, fire combined with the pipeline system or low pressure fire water supply system, you can choose to allow low pressure bearing pipe ductile iron pipe, Fire Protection System welded steel pipe, hot and cold galvanized steel pipe, and PE water pipe.

When the outdoor fire water supply system for the temporary high pressure or high pressure water supply system, and the system operating pressure is low, the pipe can be used within the allowable pressure range (1) of the pipe; when the system's working pressure is large, Work pressure situation, Fire Protection System respectively, using ductile ductile iron pipe, welded steel pipe, hot and cold galvanized steel pipe inside and outside the wall or thickened steel pipe and seamless steel pipe.

When the indoor fire hydrant system working pressure ≤ 1.0Mpa, can be used ordinary welded steel pipe, hot and cold galvanized inside and outside the ordinary welded steel pipe.

When the indoor fire hydrant system working pressure of 1.0 ~ 1.6Mpa, Fire Protection System can be thickened welded steel pipe, hot-dip galvanized thickened welded steel pipe and seamless steel pipe.
