The certification requirements for a fire detection and alarm system are outlined in the Irish Standard IS3218, this standard was updated in 2009. There are four mandatory certificates signed by the following people:

  • the system designer, the installer, the commissioning engineer and the end user/client.

There is also an optional fifth certificate for system verification. In this article we will take a closer look at the design certificate.

Design Certificate:

The system designer certifies that the system is designed  to comply with IS3218, certifies their competence to design a system and in the case of modifications to an existing system confirms that the alterations will not adversely impact on the existing system.

The design certificate includes a list of relevant system drawings as per the system design and requirements. This certificate will also record any variations from the standards. For example it may be desirable to reduce sound levels in certain patient rooms in hospitals; such variations for hospital system design can be justified with reference to HTM05-03.

Clause 4.4.3 of IS3218:2009 indicates that the design certificate should be issued before the system installation and commissioning processes begin. Ideally, a single party should maintain overall responsibility for the system design, development and implementation process. The system designer is normally competant and well placed to fulfil this roll. If this roll is assumed by another party the standard suggests that consideration should be given to the system verification process as outlined in IS3218:2009 clause 7.5.11.2
