Cleaning
In order to ensure that a fire detection system functions
correctly, it is important that detectors are regularly inspected
visually in addition to functional testing.
Detectors which appear dirty on the outside are likely to be dirty
on the inside. These can be cleaned without dismantling by using a
vacuum cleaner with a brush attachment, which will remove light
dust deposits. The detector case can be cleaned with a cloth
dampened with a solution of washing up liquid. Cleaning should be
followed by functional testing.
To ascertain the correct values referred to above, please consult
the relevant Engineering Product Guide.
