Fire exit magnet locks and push bars

[Robbie]

Good morning, Is there any mandatory law on how often these should be tested for functionality please? Guidance may offer time frames but from an enforceable stand point where would this be?

Guidance would be used as the benchmark as to what would meet the functional standards of the law. If you don't follow it you must be able to demonstrate why your alternative regime still affords an equal level of safety in relation to the risk and it must be more than 'it's too much trouble', ;we don't have the time' or 'it costs too much'.

Remember that whilst 'guidance' that "where in any proceedings it is alleged that a person has contravened a provision of articles 8 to 22B or of regulations made under article 24:

(a)proof of a failure to comply with any applicable guidance may be relied on as tending to establish that there was such a contravention"

Deviation is possible (Sainsbury's justifying weekly fire alarm test for example) but requires a lot of work to establish why it's justifiable.
