What are the requirements for the fire door of the weak motor room

The lap size of the door leaf and the door frame should not be less than 12mm; The door leaf has hinges with the door frame.

The mating activity clearance on one side should not be greater than the dimensional tolerance specified in the design drawing.

The mating activity clearance of the locked side of the door leaf and the door frame should not be greater than the dimensional tolerance specified in the design drawings; The matching activity gap between the door leaf and the upper frame should not be greater than 3mm;

The gap between the door leaves of double and multiple doors should not be greater than 3mm; The active gap between the door leaf and the lower frame or the ground should not be greater than 9mm; Gap between the door leaf and the door frame fitting surface: the gap between the door leaf and the door frame on the hinged side, the locked side and the upper frame should not be greater than 3mm; Plane height difference between the door leaf and the door frame: in the fire door.

On the opening surface, the plane height difference between the door frame and the door leaf of Tianjin telescopic barcode reader should not be greater than 1mm.

Fire alarm system in weak motor room.

1. The physical environment of the computer room: The structure, materials, and configuration facilities of the computer room must meet the requirements of thermal insulation, heat insulation, and fire prevention.

2. The computer room should have: temperature and smoke sense.

Alarms and other devices and fire-fighting equipment and facilities (gas fire extinguishing agents must be used, and dry powder and foam fire extinguishing agents are strictly prohibited.)

3. The computer room should have waterproof measures to ensure the safe operation of the computer room (the computer room is generally equipped with constant temperature and humidity devices, so it is generally forbidden to use the cooling and heating system, and if it has been used, strict leakage prevention and remedial measures must be taken for the water supply and drainage pipes of the system).

According to the regulations, the doors of the computer room and equipment room are Class A fire doors that open outward. For details, please refer to GB50016-2014 Fire Door and GB 12955-2008 Fire Door.

It has to be. Otherwise, the fire won't be able to get by. It is a wooden Class C fire door. Pipe wells.

The norm is that fire doors must be used.

The requirements are as follows, but many projects use ordinary wooden doors.

I work in telecommunications, and I've seen none of them.

It depends on the design. There are definitely two control cables, NH-KVV7. Directly from the fire hydrant pump control cabinet and sprinkler pump control cabinet to the linkage control panel of the fire center; There is also a 3 from the wet alarm valve to the sprinkler pump control cabinet.

There may be a spring: one is the fire hydrant button directly starts the pump line, and the other is to connect all the fire hydrant alarm buttons with the fire hydrant pump control cabinet. However, the new specification that began this year canceled this system, and if your project is submitted for construction after May 14, don't do this; One is the control cable of the stabilizer pump, which is the same as the main pump, but some designs do not have this; One is the control module to control the pump, now the system is getting more and more perfect, and there is generally no need to design a control module to control; One is the monitoring of the water level of the pool, which requires the installation of a monitoring module, but some projects do not design this, and it is not necessarily.

In short, there must be three control cables that need to be placed, two 7-core ones, and one three-core or two-core one. From the fire belatedly put into the pump room.
