5.3.2. 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 Metholated 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.
5.3.3. Cleaning the case and lense
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.
