The fire door monitoring system is a necessary condition for personnel evacuation in the event of a fire; Toxic and harmful gas poisoning, hypoxia, burns, and inhaling large amounts of hot air are the main causes of most fire injuries and fatalities; Among them, toxic smoke has become the leading cause of death in fires. Establishing fire zones, blocking the spread of fire and smoke, and ensuring personnel evacuation and fire rescue have become urgent issues that we need to address.

The HYFD fire door system is a product designed and developed in accordance with the requirements of GB29364-2012 "Fire Door Monitor", GB50116-2013 "Design Specification for Automatic Fire Alarm", etc., ensuring that all functions such as alarm, monitoring, control, and management can be achieved.

Scheme configuration

Normally open fire door
Option 1:
Input/output interface HYM-I/O, electromagnetic release HYFD-MR, door magnetic switch HYFD-MS
Option 2:
Input/output interface HYM-I/O, electromagnetic door magnetic HYFD-MD, door magnetic switch HYFD-MS
It is recommended to use Plan 1 for detecting normally open fire doors.
Normally closed fire door

It is recommended to use the fire door magnetic switch (integrated) HYFD-MSB for configuring normally closed fire door detection.

System Overview
Function Description
The fire door monitoring system is located in the fire control room and consists of a fire door monitor, a fire door magnetic switch (integrated), input/output interfaces, a fire door release device, an electromagnetic door stopper, a regular door magnetic switch, a low-voltage power box, etc.

When receiving a fire signal, close the normally open fire door: the electromagnetic release device receives the signal and controls the closure of the normally open fire door; Ordinary door magnetic switch, used to monitor whether the fireproof door is closed properly; The input/output interface connects the electromagnetic release device and the ordinary door magnetic switch, while uploading and downloading control signals, serving as a communication module for on-site monitoring. The integrated door magnetic switch is used to monitor the in place status of normally closed fire doors, preventing the spread of fire and smoke.

System advantages

The fire door monitoring system can focus on solving:
Linkage control: It can be linked with the automatic fire alarm system to send control signals to normally open fire doors;
Fault alarm: It is prohibited for the user to keep the normally closed fire door in a normally open state under the pretext of ensuring smooth safety exits;

Automatic closing: Double leaf fire doors should be closed in sequence; The normally open fire door should be able to close automatically in case of a fire and have a signal feedback function.

application area
It can be applied to fire doors in industrial bases, rail transit, civil buildings, public buildings and other fields.
