4.0 Maintenance
WARNING –
Installation and Maintenance must be carried out by suitably skilled and
competent personnel only.
4.1 General
Maintenance
Once correctly installed, the unit requires very little maintenance other than regular
sensitivity checks and cleaning of the lens and reflector. General Monitors recommends
that a schedule be established and adhered to.
Warning: Disconnect or inhibit external devices, such as automatic extinguishing or
fire suppression systems before performing any maintenance.
4.2 Cleaning the Lens
A clean, soft, lint-free cloth, tissue or cotton swab should be used to apply the cleaning
solution. Do not touch the lens with fingers.
a)
Wet the lens with the solution.
b)
Rub with a dry, unsoiled cloth until clean.
c)
Completely dry the lens.
d)
Repeat steps a, b and c for the reflector.
NOTE:
The removal of particulate matter and any film build-up on the lens and reflector is
necessary to ensure proper sensitivity of the system. It is recommended that the lens and
reflector be cleaned at least every 30 days or more often if the detector is located in a
particularly dirty environment.
Warning: A dirty or partially blocked lens can significantly reduce the detector’s
field of view and detection distance
DO NOT USE A COMMERCIAL GLASS CLEANER OTHER THAN “INDUSTRIAL
STRENGTH WINDEX
®
with Ammonia D”:
The lens material is sapphire. The cleaning solution should be General Monitors’ P/N
10272-1 (Industrial Strength Windex
®
with Ammonia D).
