Manual call points

The purpose of a manual call point is to enable a person discovering a fire to initiate the operation of a fire alarm system so that appropriate measures can be taken. Therefore it is important for the manual call point to be recognizable and simple to use. For this reason, the European standard has attempted to standardise their appearance and function.

 

There are basically two types of manual call points which are related to the method of operation.

  • Type A: direct operation (single action).
  • Type B: indirect operation (double action).

Both types require the breaking or the visible displacement by change of position of a frangible element forming part of the front face.

Guidance on the selection, siting and speed of response should be sought from the applicable installation rule or code of practice (e.g. BS 5839-1). For example BS 5839-1 recommends only type A with a speed of evacuation signal within 3 seconds. Other codes of practice, may require a type B installation.

This section lists manual call points approved for use in fire detection and fire alarm systems in buildings.
