When replacing the batteries you must take the following into consideration:
•
You must replace both batteries at the same time. Don’t just replace one of
them.
•
Be sure not to touch the pyro detector on the removal or replacement of the
batteries.
5.2.2. Cleaning the pyro detector
The pyro detector must be clean at all times for optimum
performance. If the pyro detector appears to have any dust,
dirt or fingerprints on it, then it should be cleaned.
To clean the pyro, use a soft cotton cloth (not a tissue), which
has been dampened with Methylated Spirits (Alcohol). Gently
wipe across the window of the pyro detector with the
dampened cloth.
Be sure not to touch the pyro detector with you fingers.
5.2.3. Cleaning the case and lens
Detectors are often left in position for long periods and spiders or other pests
might stay around the detector. It is important that the lens, especially, is kept
clean of any spider webs or pests from being in front of it. It is recommended
to keep the whole case clean by wiping over it with a soft cloth to remove dust,
pests or other obstructions as required. This will also reduce the risk of a false
alarm due to pests. Do not spray on or near the lens with insect/repellent
spray. Remember not to move the position or angle of the detector as it may
affect the performance of the detector. If in doubt, carry out a walk test to
ensure the detector is operating correctly.
