What level of door hardware can be installed on fire doors?

Fire door is one of the measures for building fire separation. It plays an important role in preventing the spread and spread of smoke and fire and reducing the loss.Some items of building hardware are essential to ensure that the fire resisting door stays closed in its frame in a fire emergency.

 

In order for the fire door to function for a long time in the event of a fire, the door hardware on the fire door must also be able to function normally even in a fire. Let us understand what level of hardware on the fire door can be installed on the fire door:

 

1.Door Hinge

When used on fire-resisting doors the hinge must be CE Marked to BS EN 1935 and have demonstrated its ability to be suitable for the intended purpose, by inclusion in the satisfactory fire test to BS EN 1634-1 or BS EN 1634-2, on a type of door assembly and configuration in which it is proposed to be used. An approved third-party certification or testing body should provide this evidence.

2.Door Lock

The lock must have demonstrated its suitability for the intended purpose by inclusion in satisfactory fire tests to BS EN 1634-1 or BS EN 1634-2, on a type of door and configuration in which it is proposed to be used. This evidence should be provided by an approved third-party certification or testing body.

Locks with low melting point (less than 800°C, or 900oC for steel doors over 90 minutes resistance) components, which are critical to the retention of the door in the closed position, should NOT be used unless proven by specific tests.

Where security is in conflict with easy egress, a full risk assessment should be made. Doors that are normally unlocked when the building or area is occupied may be fitted with locks for out-of-hours security. A thumb-turn on the inside of the door will give means of escape to anyone inadvertently locked in. Where the door will be normally locked during occupation, e.g. a dispensary or a wages office, then hardware such as panic escape devices to BS EN 1125 or emergency exit devices to BS EN 179 should be used escape panic device.
