LOCKING DEVICES


Doors without Electronic Access Control

Ideally the door should be fitted with a lock which has an automatic deadlocking facility, approximately a third of the way down from the top of the door. Additionally, a mortice deadlock latch should be installed a third of the way up from the bottom of the door and it should be used as often as is practicable. These locks must be suitable for emergency exit purposes, in that they must not require key release from within, opening being achieved by means of a handle or thumb turn. Where there is any conflict between security and fire requirements or legislation, the latter must prevail. In any case of doubt, seek the Fire Officer’s approval.

All doors must be fitted with an automatic closing mechanism, both properly adjusted and regularly maintained, to ensure that the door is secured at all times. Doors should never be left wedged open, as this not only negates any security within the building, but may also contravene any Fire Regulations.

Doors with Electronic Access Control

The remote release lock should be of a type that has an electrically operated bolt action with an automatic deadlocking facility, or is a magnetic type lock. It is imperative that the system has a safeguard incorporated, which ensures that the lock can be released in the event of a power failure.
