The
EVC-H
detector is a high quality product engineered
for reliability. In order to obtain optimum performance,
periodic maintenance is required. If proper preventative
maintenance is not carried out, there is a likelihood of
malfunction, including false alarms.

Servicing of the system should be carried out in accordance
with the requirements of BS 5839 Part 1, Fire
Detection and Alarm Systems for Buildings: Code of
Practice for System Design, Installation and Servicing.
The maintenance procedures described below, should
be conducted with the following frequency:
One month after installation:
Routine Inspection and
every 3 months thereafter.
Every 6 months:
Operational Test.
Every 12 months:
Functional Test and Cleaning.
All above frequencies of maintenance are dependent on
ambient conditions.
Routine Inspection:
i) Ensure that the detector head is secure and undamaged.
ii) Check that the heat entry apertures are in no way obstructed.
iii) Ensure that the surface of the detector’s outer cover
is clean. If there are deposits due to the presence of oil
