Section 4 - INSTALLATION
In normal use, the
EV-DP
sensor will be installed at ceiling level. Pass
the field wiring through the cable hole in the centre and from the rear
of the base. Offer up and affix the base to the ceiling or conduit
fitting with screws via the base mounting holes. Connect the field
wiring to the base terminals, as detailed on page 9 making sure the
wiring does not obstruct fitting of the detector head. Fit the sensor
head by inserting it into the base and turning clockwise until the notch
in the detector rim aligns with base locking screw. The OMNIVIEW™
360º alarm indicator permits visibility from any angle.
Note: The address must be set before the sensor is fitted into place
Fit the plastic dust cover supplied over the sensor to keep out dust etc,
until the system is commissioned. If the dust cover is not fitted and the
environment is slightly dusty, such as when building work is being
completed, for example, problems of false alarms are likely to occur
after commissioning unless cleaning of the sensor is undertaken. At
commissioning, the dust cover should be removed and discarded.
NOTE: THE PLASTIC DUST COVER MUST BE REMOVED FROM THE
SENSOR IN ORDER FOR THE SENSOR TO FUNCTION CORRECTLY.
Section 5 - MAINTENANCE
AND CLEANING
Maintenance:
The
EV-DP
sensor is a high quality product engineered for reliability.
If proper preventative maintenance is not carried out, there is a
likelihood of malfunction, including false alarms.
Servicing:
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.
