faults on data loops may cause communication errors.
Ancillary Base Sounder
Installation Guide
General
The Ancillary Base Sounder, part no. 45681-276, incorporates an XP95/Discovery base. The sounder
may be connected only to control panels which use the XP95 digital protocol.
The Ancillary Base Sounder is controlled by the detector associated with it and does not have a separate
address of its own. It operates when the remote output of the associated detector is switched and
may be used only in conjunction with control panels designed to be used with Ancillary sounders. The
sounder will not operate unless an XP95 or Discovery detector is
fi
tted.
Notes:
The Ancillary Base Sounder does not feature an alert tone and sounders can not be
synchronised.
The Ancillary Base Sounder is not suitable for outdoor use.
