Commercial detectors


There are many types of detectors on the market designed to work on different principles and fire parameters (e.g. smoke, flame radiation, convective heat etc). The selection of a detector for a particular area or application should be based on a number of factors including the following:

  • The nature of the fire hazard
  • The speed of response required
  • The need to minimize false alarms


There are other factors to be taken into account such as architecture of the building, ease of maintenance and cost, etc.

Guidance on the selection of appropriate types of detectors should be sought from the applicable installation rule or code of practice (e.g. BS 5839-1). Where a particular type of detector is not covered by the installation rule or code of practice then guidance should be sought from the manufacturer’s literature. In any case, account should be given to the notes or limitations given with the listed detector in this section.

LPCB lists detectors certified to recognised standards or to special test schedules which are developed by LPCB for detector types where suitable standards are not available or were not available at the time of the evaluation.

The standards to which we offer certification can be seen here.

Approval can also be obtained for other detection principles not detailed above. In such circumstances, LPCB can develop test criteria to evaluate products, which in time may be used for the development of standards.

The initial approval and continued approval processes for detectors are outlined in scheme document SD021.
