Old fire alarm still working? What to check

An older fire alarm that still sounds when tested is not the same as a system in known working order. Check when it was last serviced, whether the records exist, whether it is monitored and whether anything was previously reported as outstanding.

Working and known working are different things

Pressing a test button and hearing a sounder tells you that one part of the system did one thing. It does not tell you about detection across the premises, battery condition, or faults logged and never cleared.

That gap is why servicing records matter more than a single test.

What to check yourself

None of this requires technical knowledge. It is a records exercise, and it usually explains the position quickly.

  • The date of the most recent servicing record you can produce
  • Whether the premises layout has changed since the system went in
  • Whether detection covers areas that are now used differently
  • Whether the system is monitored or sounds locally only
  • Anything an engineer previously reported as outstanding

When to have it looked at

If you cannot establish when the system was last serviced, or the premises has changed since installation, having it looked at is the sensible step. It may need nothing. It may need work. Guessing is the only outcome that is certainly wrong.

We will not tell you a system needs replacing to sell you something. Where a system can be taken on, we say so.
