Section 1 - INTRODUCTION
The EV-PYS is an attractively-styled, low profile photoelectric smoke sensor
for use with Nittan ‘evolution’ protocol control panels.
The EV-PYS has a chemically etched, stainless steel insect
screen therefore reducing the ingress of insects and
airborne contaminants.
EV-PYS features:
* Optical detector, detecting visible particles of combustion
* Built in sounder
* Built in Dual Line SCI (DSCI Variant)
* EEPROM addressable (hand held programmer)
* Low profile, stylish appearance
* Supplied with protective dust cover,
(remove during commissioning)
* Low monitoring current
* OMNIVIEW™ 360º LED fire alarm indicator
* Remote indicator output
* ‘EV-PYSBCN’ auxilary ouput
* Compatible with UB-6 and EV-PYSBCN bases
Section 2 - SENSOR MODELS
The EV-PYS Photoelectric smoke sensor (with Sounder) has two terminals
for connection onto the two wire loop, the DSCI variant has four (+/- in ,
+/- out). Terminal 3 provides a switched current sink function which operates
when the detector goes into Alarm (under CIE control). This is suitable for the
operation of an auxiliary function such as a remote Indicator. Terminal 3 (RIL)
is limited to 2mA. Terminal 2 provides a pulsed output to drive the dedicated
EV-PSBCN base (which is a non-addressed Beacon only base module).
The EV-PYS DSCI has a built in Short Circuit Isolator (SCI). This is offered in
a Dual Line Isolator form, where it will break BOTH the +ve and –ve lines (by
the means of 2 x Dual FET’s). The Isolator is of the ‘Semi Active’ type, where in
the event of a Short Circuit on the loop, the Isolator will automatically Isolate.
Panel intervention (either automatically or by Engineer action), is necessary
to RESET the Isolator. However, if the Short is still present, the Isolator will
re-Isolate immediately.
Section 3 - BASE MODELS
A variety of bases are available for use with the EV-PYS sensors. It is
important to use the correct base for each application. The available base
models are:
i) UB-6 base: For standard use with EV-PYS series photoelectric sensor.
ii) EV-PYSBCN base
iii) UB-6-EV: For Non-Isolated version.

Section 4 - INSTALLATION
In normal use, the EV-PYS 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-PYS 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.

Manual: EV-PYS Manual 000028 (Changes are subject to DCRN)
The maintenance procedures described below should be
conducted with the following frequency:
One month after installation: Routine Inspection and every 3
months after.
Every 6 months: Operational Test.
Every 12 months: Functional Test and Clean.
All above frequencies of maintenance are dependent on
ambient conditions.
Routine Inspection
i) Ensure the sensor head is secure and 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 accordance with
the cleaning instructions detailed later in this manual. It
may be advisable to ensure that such cleaning is conducted
regularly in the future.
iv)Ensure no equipment which may generate combustion products has
been installed in the vicinity of the detector 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.
Operational Test
The purpose of the Operational Test is to confirm the sensor’s
correct operation in response to a smoke condition.
Note: When carrying out site testing of Analogue Addressable
Evolution detectors, the CIE shall be set to test mode prior to
beginning the tests.
i) Take any necessary precautions at the control panel to limit the
sounding of the alarm sounders/bells and any fire service
summoning device.

ii) Introduce a discrete amount of smoke into the sensor head, e.g.
using a ‘Detector Testers - Solo’ smoke test head, alternatively Detector
Testers “Testifire” smoke test equipment maybe used. Check that the
sensor gives an alarm condition within 15 seconds. Check the LED
indicator on the EV-PYS 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 sensor
previously tested does not re-operate due to the presence of
residual smoke.
Functional Tests:
The functional test checks the sensor operation. These sensors may
be returned to our factory for Functional Testing.
Cleaning:
Note: The sensor head should NOT be 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,
please return the complete sensor to Nittan (EUROPE) Ltd. for service.
