evolution.....

The EVC-PY-IS Intrinsically-Safe Photoelectric Smoke Detector forms part

of a range of ﬁre detectors from Nittan Europe Ltd. called evolution.

The EVC-PY-IS is an elegantly designed, low proﬁle detector which is

aesthetically pleasing, thus enabling it to blend unobtrusively into modern

working environments.

The EVC-PY-IS is compatible with other existing conventional ﬁre

detection systems, but is intended for use in Hazardous Areas, with the

relevant Isolator barrier.

Section 1 - INTRODUCTION

The EVC-PY-IS is an attractively-styled, low proﬁle photoelectric smoke

detector for use in conventional ﬁre detection systems.

The EVC-PY-IS has a chemically etched, stainless steel insect screen therefore

reducing the ingress of insects and airborne contaminants.

EVC-PY-IS features:

* Optical detector, detecting visible particles of combustion

* Low proﬁle, stylish appearance

* Supplied with protective dust cover (remove during commissioning)

* Non-polarised terminals

* Unauthorised head removal signal facility

* Low monitoring current

* OMNIVIEW™ 360° LED ﬁre alarm indicator

* Remote indicator output* Compatible with STB-4-IS and

UB-4-IS bases

Section 2 - EVC-PY-IS

The smoke chamber of the EVC-PY-IS is constructed so that light cannot enter

from outside, but smoke can pass through the chamber slots. The EVC-PY-IS

utilizes the light scatter sensing principle. An alarm condition is veriﬁed before

an alarm is given.

The detector design provides strong immunity to air velocities, contamination

and RF interference.

The geometry of the smoke chamber and optics support assembly is designed

to give the best possible signal to noise ratio, resulting in excellent response

characteristics.

Section 3 - DETECTOR MODELS

The EVC-PY-IS photoelectric smoke detector is supplied, as standard, with

four terminals.

The EVC-PY-IS has the facility to activate a remote LED indicator or auxiliary

function, as standard.

The terminals on the EVC-PY-IS detector head are conﬁgured as follows:-

Terminal 2 = zone positive in/out

Terminal 1 = zone negative in

Terminal 6 = zone negative out

Terminal 5 = 2mA @ 24V d.c. switched output

Section 4 - BASE MODELS

It is important to use the correct base for the EVC-PY-IS intrinsically-safe

smoke detector.

The UB-4-IS base is designed exclusively for use with EVC-PY-IS detector;

this base has 4 terminals including an auxiliary output function.

The STB-4-IS base is mechanically and electrically compatible with the EVC-

PY-IS detector and may be used as an alternative.

Section 5 - INSTALATION

In normal use, the EVC-PY-IS detector 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 detector head by inserting it into the

base and turning clockwise until the notch in the detector rim aligns with

base locking screw. The OMNIVIEWTM 360° indicator permits visibility

from any angle.

Fit the plastic dust cover supplied over the detector 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 detector is undertaken. At

commissioning, the dust cover should be removed and discarded.

Note: The plastic dust cover must be removed from the detector

inorder for the detector to function correctly.

Section 6 - MAINTENANCE AND

CLEANING

Maintenance:

The EVC-PY-IS 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, as a dirty detector is more likely to cause a false alarm.

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.

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 detector’s outer cover is clean. If there

are deposits due to the presence of oil vapour, dust etc, then the

detector 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 or

ﬁne airborne particles, 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.

• Ref No: NISM/EVC-PY-IS/02 • 19.02.19 • Issue: 2

• Evolution • EVC-PY-IS • Conventional Intrinsically-Safe Photoelectric Smoke Detector

Operational Test

The purpose of the Operational Test is to conﬁrm the detector’s correct

operation in response to a smoke condition.

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 detector head, e.g. using

a ‘No Climb-Solo’ smoke test head. Check that the detector gives an

alarm condition within 15 seconds. Check the LED indicator on the

EVC-PY-IS detector illuminates and any remote indicator LED ﬁtted also

illuminates.

iii) After the detector has given the alarm condition, reset the detector from

the control panel. It may be necessary to allow a short time to elapse

before resetting the detector, to allow any residual smoke from the test to

disperse.

iv) Before proceeding to the next detector, ensure that the

detector just tested does not re-operate due to the presence of

residual smoke.

Functional Tests:

The detector may be returned to Nittan Europe Ltd for functional testing.

Cleaning:

Note: The detector head should NOT be disassembled.

i) Carefully remove the detector 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 compl

ete detector to Nittan Europe Ltd. for service.
