Fire Performance



The prime purpose of a fire door is to protect lives and offer compartmented protection to the remainder of a building, and to other buildings. A high quality locking system is a vital component within a fire doorset assembly, ensuring the door leaf is properly restrained within the frame for the maximum time possible, to resist the passage of flame and spread of fire.

MICO High Security Locking Systems are eminently suitable for this application, having proven capability to perform in the event of a fire. A number of MICO single and multipoint locking devices have successfully attained the maximum 4 hour fire integrity duration, in accordance with the latest British and European Standard BS EN 1634-1 when tested with our OEM partner’s doorset products.

Our fire tested locking systems may also be specified on fire escape doors to ensure a swift single operation means of egress when an alarm is raised. These locks can be fitted with either an escape lever handle, push pad or panic bar device and are fully compliant with current safety standards and regulations.
(Specify SATE = Single Action To Escape function).

MICO access controlled locks can be specified with fail safe or fail secure functionality.

Fail safe locks require power to lock. When power is interrupted by the access control system, fire alarm or power outage the lock will release.

Fail secure locks require power to unlock. When energised by the access control system the lock will release and remain released whilst the lock is energised. Fail secure versions are used where a door needs to prevent unauthorised entry, life-safety egress can still be selected when ordering these locks.
