Voltek Automation IS2000 MK1 Intrinsically Safe PIR Detector Installation Instructions

IS2000 - Intrinsically Safe PIR Detector
Installation Instructions
INTRODUCTION
-
The IS2000 is an ATEX and IECEx approved and
certified product designed specifically for use in
hazardous areas such as the petrochemical
industry, gas plants, explosive manufacturing /
storage,
pharmaceutical
industry,
sewage
treatment plants, ……. indeed anywhere there is a
potentially explosive atmosphere.
The detector is a movement sensor that works by
looking for moving body heat (infra-red energy).
The detector will connect to your alarm system or
other control equipment to warn of human
presence.
The IS2000 must be used with an approved barrier
which will limit the voltage and current to approved
levels for the IS2000.
A suitable zener barrier can be found in the ZE
Interface Unit, which also incorporates signal
processing electronics to provide a perfect
interface between the IS2000 and your control
equipment. The ZE Interface would be installed in
a non-hazardous area and connected with a four
core cable to the IS2000 within the hazardous
area.
Please Note: the operating temperature range for
this device is –20oC to +40oC, which may differ
from that specified in the IS2000 brochure

TYPICAL APPLICATIONS
•
•
•
•
-
Connection to your alarm system to warn of an
intruder in a hazardous area
Warns your control room that factory
personnel are in a prohibited area
Connects to your hazardous area lighting
controller to switch them on only when people
are in the area, hence this will reduce your
electricity consumption
Increases the life of your battery powered
emergency lighting by switching them on only
when a presence is detected.

WHO CAN INSTALL THE IS2000 ?
-
The installation of this equipment must be
performed by engineers with the necessary
experience to work in hazardous areas.
We recommend that you are familiar with BS 5345
part 1 (Selection, installation and maintenance of
electrical apparatus for use in potentially explosive
atmospheres – General recommendations) & BS
5345 part 4 (installation and maintenance
requirements for intrinsically safe electrical
apparatus and systems)
HOW DOES A PIR DETECTOR WORK ? A PIR (Passive Infra Red) sensor will detect a
person’s infra red energy (body heat) when it
moves into it’s field of view. The sensor works by
splitting the area up into detection zones, as shown
in the coverage diagrams below. Whenever a
person is seen moving from one zone to the next,
the sensor will output a signal. The high quality
components, sophisticated filters and noise-free
amplifiers ensure that valid alarms will be
recognised.

SITING THE IS2000 PIR DETECTOR
-
For best results locate the sensor so that
movement is across the detection pattern
rather than towards the detector. You will
notice from the detection pattern above, that a
person would cross more beams this way and
the sensor would therefore be more sensitive.
The detector should be mounted at a height of
2.5 to 3 metres for best results.
The unit should be fixed to a rigid, vibration
free vertical surface for reliable operation.
To minimise the possibility of false alarms,
avoid aiming the IS2000 at windows which
may have sunlight shining on them. Also, do
not locate the detector close to heater flues,
heat exchangers, or air conditioning equipment
that may emit warm moving air.
Locating the detector close to branches of
trees or bushes may also cause a false alarm
as these do emit infra-red energy
WHAT ELSE DO I NEED ?
-
The IS2000 package contains an Intrinsically Safe
PIR Detector, a mounting bracket and these
installation instructions. You will also require the
following to complete the installation:

3 x size 12 by 30mm self tapping screws and
appropriate rawl plugs for affixing the mounting
bracket to the wall
M20 screw cable gland suitable for IP67
weatherproofing, for the IS2000 cable entry
4 core cable suitable for the hazardous area,
including cable clips, cable trunking etc if
required. (The cable must comply with your
building regulations and ‘interconnecting
cables’ section of BS 5345 part 4)

INSTALLATION PROCEDURE
Condition of safe use (X Condition). The IS2000
unit must be carefully located during installation to
avoid an ignition hazard due to impact or abrasion.
1.
When the mounting position is chosen, fix the
bracket to the wall utilising the three mounting
holes. Ensure the bracket is in a vertical
position with the PIR support arm at the top.
2.
Hang the IS2000 rear enclosure from the
bracket using the bolt provided.
3.
Run a suitable 4 core cable from the zener
barrier or ZE interface unit to the PIR detector
and feed the cable through the cable entry
hole in the rear enclosure and seal using a
M20 cable gland (not supplied).
4.

7.
Push the front enclosure into place ensuring
that no cables are trapped and that the gasket
is sitting in place properly
8.
Fasten the six bolts on the front of the
enclosure, using a 10mm socket, to secure the
front into place and provide a dust tight seal.
CONNECTING TO A ZE INTERFACE

By connecting to a ZE Interface unit, this already
has a zener barrier installed and pre-wired to a
signal processing board. The output is an alarm
standard, voltage free, normally closed relay, for
each IS2000 connected. Follow the instructions
supplied with the ZE Interface unit for installation
and connections details.
