NITTAN (UK) LTD - BRINGING STYLE INTO FIRE DETECTION SYSTEMS
The new EV-DP advanced analogue addressable smoke sensor forms part
of a brand new range of analogue addressable fire sensors from Nittan (UK)
Ltd called evolution-advanced.
The EV-DP together with the EV-PH, EV-H, EV-P and EV-UV are all elegantly
designed, low profile fire sensors which are aesthetically pleasing, thus
enabling them to blend unobtrusively into modern working environments.
The evolution analogue addressable range all feature the very latest
technological advancements such as ASIC design, increasing reliability and
performance.

'evolution' protocol control panels.
The EV-DP has a chemically etched, stainless steel
insect screen therefore reducing the ingress of insects
and airborne contaminants.

Section 3 - BASE MODELS
A variety of bases are available for use with the EV-DP
sensors. It is important to use the correct base for each
application. The available base models are:
i)STB-4-EVbase:Forstandardusewith EV-DP series

ii) STB-4SE-EV base: Similar to STB-4-EV base, except
deeper.

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.
Note:Theaddressmustbesetbeforethesensoris
fittedintoplace.
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.

Section 7 - ENVIRONMENTAL
PARAMETERS
TemperatureConsiderations:
Over the range from -10 oC. to +55 oC.
Humidity:
Relative Humidity of up to 95%, measured at 50 oC,
non-condensing.
Section 8 - EMC
Installation
The installation shall be in accordance with the
regulationseitheroftheapprovalbodyforanapproved
system, or otherwise, to the national code of practice/
regulations for the installation of the fire alarm system,
e.g. BS 5839 part 1.
Electromagnetic Compatibility (EMC)
On a site where there is an unusually high level of
potential electrical interference, e.g. where heavy
currents are being switched or where high levels of R.F.
are prevalent, care then must be taken in the type and
routing of cables. Particular care should be given to the
separation of zone wiring from the cable carrying the
interference.
Cleaning:
Note:ThesensorheadshouldNOTbe
disassembled.
i) Carefully remove the sensor head from its base.
ii) Use a soft, lint-free cloth, moistened with alcohol for
sticky deposits, to clean the plastic casing.
iii) Using a soft bristle brush (e.g. an artist's paint-
brush) carefully brush between the vanes in a linear
motion away from the smoke entry apertures.
iv) It is permissible to blow dust from the chamber,
without removing the cover, using a clean air line.
v) If the unit needs further cleaning, or is damaged or
corroded,pleasereturn the complete sensor toNittan
(UK) Ltd. for service.

• If the current password is not to be changed, press ‘OK’ with ‘Enter’ selected. The address programmer
will then scan for the attached sensor.
• If a sensor is fitted the programmer will report the sensor’s current address and its group, then prompt
for the next address to be programmed. The current address can be changed by simply entering a new 3
digit address, then pressing ‘OK’.

• If no detector is fitted, the programmer will report 'No Unit Found, Comm Error 1'. Fit a new sensor and
press ‘OK’.
• At any time there has been no key pressed for 30 seconds, or no programming operation is being carried
out, the backlight will switch OFF and the programmer will revert to its ‘Sleep’ mode in order to preserve
battery life.

• When the power supply is attached, the programmer will start a Fast charge cycle which will last for
2 hours, then automatically switch to trickle charge. Overnight charging (12 hours) is sufficient to fully
re-charge the batteries. Fast charge and trickle charge status is indicated by two LEDs.
