1. Introduction
This document covers the installation of the Gazelle Family of People Counter products
for both surface-mount and recess-mount variants.
For guidance on selecting the correct mounting position please refer to the application
notes document (IPU 40184).
2. Surface Mount Installation
2.1
Requirements:
IRC 5xxx-xx Gazelle Core
IRC 500W or IRC 500B Surface Mounting Kit
Fixing Screws – Not supplied
2.2
Procedure:
The base should be mounted on a firm, level surface.
Ensure that the traffic flow direction arrows of all units are pointing in the same
direction, preferably in the direction of traffic flow as indicated by the arrow in the centre
of the base, shown as “A” in Figure 1.
Figure 1 Surface mount base detail
Alignment marks are provided at the edge of the base as shown as “B” in Figure 1.
Remember that the centre of the base is not the centre of the cover since this allows
space to cover the cable entry.
The cover centre is indicated by “D” in Figure 1.
The cover is designed to hide cable connections. These can be taken through an
appropriate sized hole in the ceiling (within the profile of the cover – see Figure 2 ) or
the edge of the cover may be cut if surface conduit is being used (see Figure 2).

Figure 2
Areas for cable entry
Install the base using the mounting holes provided. The slots allow for a limited amount
of movement in the base. When the base is aligned correctly, tighten all screws and, if
necessary, secure the base using one of the two locking screw positions shown as “C“ in
Figure 1.
The Gazelle core can now be clipped into the base by first inserting the two tabs at the
connector end of the core into the base and then clipping the tab on the opposite face as
shown in Figure 3. (Ensure the tab clips in place).
Figure 3 Clipping core into base
Remove the lens cover and cap as appropriate (see Figure 4 Lens cover) before fitting
the cover. Ensure the lens is not rotated when removing the cap.

The cover is supplied with two blanking plugs pre-fitted. Remove the IR blanking plug
(and, for the Gazelle Dual-view (IRC571x-xxx), remove the Video blanking plug) as
shown in Figure 5
Figure 5 Blanking plug detail
The cover is clipped onto the base and can be removed for access by pressing the clips
on either side with a small flat bladed screwdriver (see Figure 6). Take care to not
damage the surface finish of the cover.

3 Recess Mount
3.1
Requirements:
IRC5xxx-xx Gazelle Core
IRC510W or IRC510B Recess Mounting Kit
(114mm (4½“) Cutter, Saw, Drill)
3.2
Procedure:
The recess mount base should be mounted on a firm, level surface. Ensure that the
traffic flow direction arrows of all units are pointing in the same direction, preferably in
the direction of traffic flow as indicated by the arrow in the centre of the base shown as
“A” in Figure 7.

Figure 7 Recess mount base detail
Locate the base in the required position. It has two points to assist with alignment
shown as “B” in Figure 7. Mark two locations onto the ceiling through the holes shown as
“C” in Figure 7.
Figure 8 Ceiling hole cut-out detail
These form the centres for two 114mm diameter holes to be drilled as shown in Figure 8.
After drilling the holes with a suitable cutter (114mm or 4½ inch), cut along the dotted
lines shown in Figure 8. This hole will be slightly bigger than the base, allowing it to be
aligned at the final stage of fitting.
The base is held against the ceiling using two semi-circular brackets shown in Figure 9
(and 4 x M4 25mm Countersunk Bolts supplied).

Figure 9 Recess mount bracket
These can be used in one of two orientations, depending on the type of ceiling. For a
thin ceiling they should be used with the bushes uppermost, but for ceilings thicker than
5 mm (3/16”) the bushes should be recessed into the ceiling as shown in Figure 10.
Figure 10 Recess mount bracket orientation
To determine the correct drill locations, place the base into the hole in the ceiling and
align it using the marks “B” in Figure 7 then mark the drill positions using centres of the
slotted holes shown “D” in Figure 7. Drill the relevant sized holes in 4 positions.
Locate the base into the ceiling and then place the bracket above the ceiling. Using the
bolts provided to secure the bracket, loosely fix the base in place. Make a final check of
the base alignment and then tighten the four bolts to secure the base in position.
The Gazelle core can now be clipped into the base by first inserting the two tabs at the
connector end of the core into the base and then clipping the tab on the opposite face as
shown in Figure 11. (Ensure the tab clips in place).

Remove the lens cover and cap as appropriate (see Figure 12 ) before fitting the cover.
Ensure the lens is not rotated when removing the cap.
Figure 12 Lens cover and cap
The cover is supplied with two blanking plugs pre-fitted. Remove the IR blanking plug
(and, for the Gazelle Dual-view (IRC571x-xxx), remove the Video blanking plug) as
shown in Figure 13
Figure 13 Blanking plug detail
Once cabling and commissioning is complete (see below) the cover is clipped onto the
base and can be removed for access by pressing the clips on either side with a small flat
bladed screwdriver (see Figure 14). Take care to not damage the surface finish of the
cover or the ceiling.

4 Cabling
The cable connections are shown in Figure 15.
Figure 15 Cabling Connections
4.1 Power
The counter can be powered from either the IP connection (PoE) or 12-28V DC via the
power connector but only one connection should be made. Do not exceed the maximum
100m length for IP connections.
Page 9 of 12
4.2 CAN
If CAN nodes are to be utilised, then they are connected via RJ45 patch lead connections
(straight through configurations) from the black RJ45 connector to a black RJ45
connector on the node (either black connector can be used). There may be a maximum
of 5 nodes connected to an IP Master (IRC57xx-Mxx) counter’s CAN–Bus in a ‘daisychain’ style when using POE. (Note the IP counter does not need to be at the end of the
‘chain’.)
If a Dual-View (IRC571x-Mxx) counter is being installed then the nodes must be
positioned either side of it so that they are in the field of view of the video.
Devices at either end of the CAN-Bus should be terminated correctly by inserting the
CAN terminator (IWC3063 see Figure 16) supplied, into the last free black RJ45 socket at
each end of the CAN-Bus. Consequently, there should be no RJ45 sockets which do not
contain either a cable or the CAN terminator.
Figure 16 CAN terminator
4.3 I/O Connections
Figure 15 shows the connections for Relay Signalling and Inputs to the Gazelle unit. For
detail of how these are used refer to IPU 40527 Gazelle Systems Integration Guide.
Where more than one counter is used (e.g. for wide opening entrance) only the Master
device would use this interface.
5 Configuration
5.1
SD Card
All Gazelle Dual-view counters (IRC57xx-Mxx) are supplied with a 4GB MicroSD card
installed. This can be removed by pressing on it in the socket (see Figure 17). Higher
capacity cards can be used – consult Irisys for advice.

Figure 17 SD Card socket
5.2 Counter Configuration
All counters require configuring before use. Connecting to the IP Master counter allows
configuring of all counters connected to that master via the CAN bus.
The preferred method of configuring the counter is to use an Internet browser to connect
to the counters’ network port, however if a serial connection is required, connect the
IWC 3062 USB/serial cable ‘headphone’ type jack to the counter (as shown in Figure 18)
Figure 18 Set-up cable connection
For information on configuring the counter, refer to the People Counter Setup tool
Software Manual (IPU 40521)
