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 6
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
OMNIVIEWTM 360o alarm indicator permits visibility from
anyangle.

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, includ-
ing false alarms.
Servicing:
Servicing of the system should be carried out in accord-
ance 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.
Every6months: OperationalTest.
Every 12 months: Functional Test and
Clean.
Allabovefrequenciesofmaintenanceare dependenton
ambient conditions.
RoutineInspection
i) Ensurethe sensor head is secureand undamaged.
ii) Check the smoke entry apertures are in no way
obstructed.
iii) Ensure the surface of the sensor’s outer cover is
clean. If there are deposits due to the presence of oil
vapour, dust etc, then the sensor should be cleaned in
accordancewiththe cleaninginstructionsdetailedlater
in this manual. It may be advisable to ensure that such
cleaningis conducted regularly inthefuture.
iv) Ensurenoequipmentwhichmaygeneratecombus-
tion products or fine airborne particles has been in-
stalled in the vicinity of the sensor since the last routine
inspection. If such equipment has been installed, then
you should notify the Fire Safety Officer or other
competent authority that its presence may cause false
alarms.
OperationalTest
The purpose of the Operational Test is to confirm the
sensor’s correct operation in response to a smoke
condition.
Note:When carryingoutsitetestingof Analogue
AddressableEvolutionsensors,theCIEshallbeset
totestmode priortobeginning thetests.
i) Take any necessary precautions at the control panel
to limit the sounding of the alarm sounders/bells and
anyfireservicesummoningdevice.
ii) Introduce a discrete amount of smoke into the sensor
head, e.g. using a 'No Climb - Solo' smoke test head.
Check that the sensor gives an alarm condition within 15
seconds. Check the LED indicator on the EV-DP
sensor illuminates and any remote indicator LED fitted
also illuminates.
iii) After the sensor has given the alarm condition, reset
the sensor from the control panel. It may be necessary
to allow a short time to elapse before resetting the
sensor, to allow any residual smoke from the test to
disperse.
iv) Before proceeding to the next sensor, ensure that the
sensorpreviouslytesteddoes not re-operateduetothe
presence of residual smoke.
FunctionalTests:-
The functional test checks the sensor operation. These
sensors may be returned to our factory for Functional
Testing.
