Connecting an Alarm
2.
Connect the two contacts of the sensor to the Sensors terminal block on
the rear panel of the IVG-400 (see
Figure 1
, page 1), as illustrated in
Figure 7.
Note: The wires must be connected to two adjacent contacts in the same
group (e.g., the two contacts of “In1”), but the polarity does not matter.

Connecting an Alarm
Up to two alarms and other devices that are activated in response to detected
events can be connected to the IVG-400. Essentially, the IVG-400 functions as
an on/off switch for these devices.
A power relay is required for the alarm to be connected to the IVG-400 properly.
Release 1 of the IVG-400 does not have a built-in relay. To connect an alarm to a
release 1 unit, you must acquire a relay and connect it externally. In release 2 of
the IVG-400, the relay is built into the unit. Instructions for connecting an alarm,
with or without a built-in relay, are provided below.
Connecting an Alarm in Release 1
To connect an alarm to a release-1 unit, which does not have a built-in relay,
follow the instructions below.
Note: The connections are illustrated in Figure 9 below. See
Figure 1
, page 1, for
a diagram of the IVG-400 rear panel, including the locations of the 12VDC
Power Out connector and the Activators terminal block.
1.
Acquire a 12VDC power relay, such as the Fujitsu FTR-MYAA012A.
2.
Install the alarm in its desired location in the vehicle.
3.
Connect the right (+) contact of the 12VDC Power Out connector to
Relay/1.
