Connecting the Aerial

There are three types of aerials that can be attached to iSense Units:

Articulated, knuckle jointed, aerial (G205). See Figure 196 below:

Setup iSense 3

Figure 196

Can be used indoors or outdoors

Dome aerial (G455). See Figure 197 below:

Setup iSense 4

Figure 197

Suitable for use outdoors

Remote mounted Flat Blade aerial (AM36913). See Figure 198 below:

Setup iSense 5

Figure 198

Suitable for indoor use only.

Extended antenna for low signal areas.

Choose the aerial that best suits the environment where the iSense unit will be located and simply screw it or the aerial's cable connector, into the brass coloured Aerial connection found on the top of the iSense Unit.

Caution: Do not use excessive force tightening the aerial connection, finger tight is adequate.

The Aerial/Unit should be positioned to ensure a good RF signal.

Caution:Fit sensors and aerial before connecting power or batteries. See Figure 199, Figure 200, Figure 201 and Figure 202 below.

Inserting the Batteries

Note:The IS08 unit has no provision for battery power, being powered only from an external power supply.
Note:If you have ordered an External Power Unit, you will be provided with a 12VDC Desktop Power Supply (G422) instead of batteries. See Figure 199 below:

Setup iSense 6

Figure 199
Batteries Inserted

1.Remove the Unit’s front cover.

2.Insert the 2 x 1.5V Alkaline C cell batteries (88702) or 2 x 3.6v Lithium C cell battery (88704) into the battery holders. See Figure 199 above.

Caution: Be sure to insert the batteries in their correct orientation – the correct polarity is embossed on the battery holders.

External Power Supply (12VDC Power Supply Unit or 12VDC/24VDC Vehicle Supply)

Caution: Vehicle power should be sourced from as ‘clean’ a supply as possible.
If using an External Power Supply, DO NOT fit batteries to the holders.
Note:The 12VDC or 24VDC external supply is protected by a 0.5A fuse.

Connecting the Power Supply Cable (if External Power Supply specified):

1.Remove the Unit’s front cover. See Removing the Front Panel above.

2.Loosen the right-hand input gland. See Figure 200 below:

Setup iSense 7

Figure 200

3.Feed the 12 or 24V Power Supply Cable through the right-hand cable gland.

4.Thread the exposed wires up the gland until there is enough length for the wire to reach the right-hand connector block.Figure 202 below:

5.Tighten the gland.

6.Using a screwdriver, press down in turn on the terminal block’s Terminal Release Levers to open the Common GND (-ve) and +12V In or +24V In (+ve) connectors. See Figure 201 below:

Setup iSense 11
