Design of Fire Door Monitoring System

Set the original intention

Functions and functions of fire doors
Fire doors are an important part of fire partitions and fire intervals in buildings. Can effectively prevent the fire from spreading,
Flue gas diffusion; At the same time, it is the only pass for personnel to evacuate safely and firefighters to put out fires.
The opening and closing of fire doors plays a vital role in the evacuation of people. Therefore, the fire prevention of evacuation routes
Door status information must be fed back to the fire door monitor in the fire control room or manned premises.
Fire door monitoring system and fire emergency lighting evacuation indication system are the cause of fire
Necessary conditions for crowd evacuation
When a fire breaks out in a building, people's lives must be protected first, and people indoors must be evacuated immediately.
The emergency lighting and evacuation indication system is started to provide lighting and evacuation methods for the evacuation scene for the crowd
Instructions to.
The fire door should be closed (the normally open fire door should be closed in conjunction, which can be opened manually), and the firewall,
Fire shutter forms an effective fire zone, isolates the spread of fire, and more importantly, prevents the spread of smoke.
Provide necessary aerobic environment for crowd evacuation.

Is the fire door normal in use? Normally closed and normally open; Normally closed does not open
When a fire breaks out, if the fire door is not closed normally, it is a common abnormal opening state. This way
The integrity of the fire zone is destroyed, and the toxic smoke generated by the fire is bound to spread to the evacuation passage wantonly.
Seriously threaten the life safety of evacuated people in buildings. The implementation of fire door monitoring system can effectively integrate
1. Monitor the opening, closing and fault status of fire doors, and keep them in normal state through management means.
On the contrary, there are multiple owners in the building or each functional area has different usage needs. According to security needs, it will be one-way or
Fire doors on the evacuation passage are locked in two directions. During emergency evacuation, these locked fire doors make the evacuation passage form
Impassable dead end, evacuated people have no way to escape, causing casualties. Therefore, during evacuation, it can be monitored by the fire door
The fire door locked by the control system is linked to the security to make it in an openable state.
Functions of fire door monitoring system
Monitor the opening, closing and failure status of all fire doors located in the evacuation passage;
During emergency evacuation, close the normally open fire door jointly.

It is issued by the fire alarm controller or fire linkage controller, and should be connected by the fire linkage controller or fire door monitor
Dynamically control the fire door closing.
2 The opening, closing and fault status signals of each fire door on the evacuation passage should be fed back to the fire door monitor.
4.10. 2 The fire linkage controller should have the function of automatically opening the electric grid pole involved in evacuation.
4.10. 3 The fire linkage controller shop has the function of opening the doors and courtyard electric gates controlled by the access control system on the evacuation passage
Yes, and should have the function of opening the stop bar at the entrance and exit of the parking lot.
6 Settings of system equipment
The fire door monitor should be set in the fire control room. When there is no fire control room, it should be set in a place where people are on duty.
The manual control button of the electric door opener should be set on the inner wall of the fire door, the distance from the door should not exceed 0.5 m, and the bottom edge should be high from the ground
The degree should be 0.9 m ~ 1.3 m.
The setting of the fire door monitor shall meet the installation and setting requirements of the fire alarm controller.

General Technical Requirements for Fire Control Room GB25506-2010
5 Control and display requirements
5.3 Fire linkage controller
5.3. 9 The control and display of fire doors and fire shutter systems shall meet the following requirements:
A) It should be able to display dynamic information such as the working status and fault status of the fire door controller and fire roller shutter controller;
b) It should be able to display fire shutters, normally open fire doors, evacuation doors that are normally closed due to management needs in crowded places and
The working state of the fire door with the signal feedback function;
c) It should be able to close the fire shutter and normally open fire door and display their feedback signal.

Code for Fire Protection Design of Buildings GB50016-2014
6.5 Fire doors, windows and fire shutters
6.5. 1 The setting of fire doors shall meet the following requirements:
1. Fire doors set in places where people often pass straight in buildings should be normally open fire doors. Normally open fire doors should be able to withstand fire
It turns off by itself and should have the function of signal feedback;
2 Except for the locations where normally open fire doors are allowed, fire doors in other locations should be normally closed fire doors. Normally closed defense
The fire door should be equipped with prompt signs such as "keep the fire door closed" in its obvious position;
3. Except for access doors and residential doors, fire doors should have self-closing functions. Double-leaf fire doors should have
The function of sequential self-closing;
4 In addition to the provisions of paragraph 4 of Article 6.4. 11 of this specification, the fire door should be able to be manually opened on its inner and outer sides;
5. When installed near the deformation joint of the building, the fire door should be installed on the side with more floors, and the fire door should be ensured to be open
When the door leaf does not cross the deformation joint:
6 The fire door should have smoke-proof performance after being closed:
8.1. 7 Set up automatic fire alarm system and automatic fire extinguishing system or set up automatic fire alarm system and mechanical prevention (discharge)
Buildings (groups) with smoke facilities should be equipped with fire control rooms. The installation of the fire control room shall comply with the following requirements:
1. The fire resistance level of a separately built fire control room should not be lower than Grade II;
2 The fire control room attached to the building should be installed on the first floor or underground floor of the building, and should be arranged against the exterior wall
