Modifying an Existing Fire System

Buildings, and the way we use them, often change and sometimes that means the existing fire detection and alarm system can become inadequate. For example, when internal office layouts change, or when space is used for a new activity, or when structural changes take place. Of course, sometimes the old system just can not be maintained to current exacting standards anymore, which is why we overhauled the fire system at Perth Leisure Pool over a four month period in 2008.

Our starting point is to re-assess the fire risk against the latest regulations and identify what fire protection is now required.

We go back to our as fitted drawings and inventory of the installed equipment, and from there list the modification works. When significant changes are required, our Fire Systems Designer may survey the premises and draw up a new specification and proposal.

If the original drawings and equipment inventory is not available, our Fire Systems Designer will survey the premises and identify the condition and serviceability of existing detection devices, the control panel type and condition, the condition of electrical wiring, and whether or not there are any obvious false alarm hazards in the existing design, or non-compliances with British Standards and Codes of Practice.

From there, a proposal for remedial work and the extended coverage is drawn up, and work follows much the same process as for a new system. We will procure all additional equipment from our trusted suppliers and schedule the work to minimise disruption to the building users. Once installed, the system is tested and commissioned. We update the ‘as fitted’ drawings, zone charts and other paperwork, and issue the Modification Certificates and Fire Alarm Log Book.

We train your nominated Responsible Person on what to do in the event of an alarm activation, and how to test the system periodically as part of your Fire Safety Policy.

Our over-riding goal in any modification work is to ensure your continued compliance to the requirements of Fire (Scotland) Act 2005 and Standards such as BS 5839 and BAFE SP203
