Compartmentation This protocol involves the creation of


a secure external box, which is mounted near the main entrance of the building (and at other locations in larger developments), and inside which is a switch for the use of firefighters. The box is accessed via a secure restricted lock; the keys to which are carried on the fire tender. Once the switch is operated, the access or


door control system is rendered safe (open). This includes all internal compartmental doorsets operating on the system. The box itself should be certificated to a minimum of STS 205 BR2.


Practical solutions


Another SBD member company, Gerda Security Products, was one of the first fire doorset manufacturers to achieve third party certification for both fire and security across its various doorset ranges. In addition, the company has launched an externally mounted Access Control Box (ACB), which is designed specifically for communal entrance doorsets in new build, multi occupancy residential accommodation. As well as limiting illegal


access to buildings, the ACB enables the fire service to gain immediate entry by deactivating external and internal doors that are secured by electronic or electrical systems, using Gerda’s key management technology. Jon Cole, SBD’s chief operating officer,


concluded: ‘I believe that the number of arson attacks in developments of flats would be reduced significantly using compartmentation to limit access to all but residents and their legitimate visitors. I have visited many blocks of flats where rubbish has accumulated under stairwells and then been set alight by people who have managed to gain access to the development. Such incidents often leave behind a tell-tale, blackened base to the stairwell.’
