Group Address Setting
In group mode the XP95 Base VAD and Sounder VAD variants respond to an additional address referred
to as the group address, which is used to activate groups of base variants, Integrated Base Sounders and/
or 100dB sounders simultaneously. Individual units continue to respond to their own addresses and report
their status in the normal way. A group address is set on a four-segment DIL switch which is factory set to
0000. A group address may be any spare address within–and only within–the range 112 to 126 inclusive.
The required group address is set in accordance with the following table. For an illustrated example, please
see Fig. 2.

irrespective of the protocol message.

Address Setting
The address of the XP95 Base VAD and Sounder VAD variants are set using seven segments of the eight-seg-
ment DIL switch. The eighth seg ment is used to adjust the volume output. Segments 1-7 of the switch are set
to “0” (ON) or “1”, using a small screwdriver or similar tool. A complete list of address settings is shown below.
If a detector is to be
fi
tted, set the address as described on page 4.
