Frequently Asked Questions — Fire Alarms
What is the difference between a conventional and addressable fire alarm?
A conventional system divides a building into zones — if a detector activates, you know which zone. An addressable system identifies the exact device that has activated, which is essential for larger buildings. We install both depending on the size and layout of your premises.
How often does a fire alarm need to be serviced?
BS 5839-1 requires professional servicing every 6 months for commercial premises. Recent guidance allows a 5–7 month window for scheduling visits. Weekly user tests are also advised — these take about 2 minutes and involve activating one call point.
Do you install fire alarms in HMOs?
Yes. HMO fire alarm requirements depend on the number of storeys and occupants. We install Grade D and Grade A systems as required by your local authority and the Regulatory Reform (Fire Safety) Order 2005.
Can you take over servicing an existing fire alarm?
Yes. We inspect your existing system, assess its condition, update any outstanding maintenance, and place it under our service contract.
Do you provide emergency fire alarm call-outs?
Yes, we offer 24/7 emergency call out for fire alarm customers who are under our maintenance contract with a visit made within 8 hours.
What documentation do I receive after installation?
You will receive all relevant compliance documentation once the final balance has been paid which includes a log book.
