Volume Control
The volume control can be used to reduce the sound steplessly from 85dB(A) to 70±5dB(A).
Functional Test Data
The Ancillary Base Sounder is loop powered and controlled by the control panel using output bit '0' in the
communication protocol.

Troubleshooting
Before investigating individual units for faults, it is important to check the system wiring is fault free. Earth
faults on data loops may cause communication errors.

Installation Guide
General
The Ancillary Base Sounder, part no. 45681-276AMP, 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 fitted.
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.
Mounting Instructions
The Ancillary Base Sounder may be secured to a UK standard conduit box or surface mounted (providing
there is access through the surface for cabling).

Wiring details
Note: The sounder is polarity sensitive (supply reversal protected) and will not function if it has been
wired incorrectly.
Connect the positive and negative XP95/Discovery loop cables to the L2 and L1 terminals respectively,
observing polarity. The wiring terminals accept solid or stranded cables up to 2.5mm². Functional earth
or screen cables may be terminated to the EARTH connection.
Address Setting
The address of the base sounder is set by means of the XPERT card. A complete diagram of address
settings is shown below.
XPERT card addressing
Select the desired address and remove the pips indicated in black. Remove pips with a screwdriver.
Maximum Loop Current Consumption at 24V
Quiescent <100μA
Operated 85dB(A) 3.2mA
The maximum number of Ancillary Base Sounders with detectors permitted between standard XP95
isolators is 20. If this limit is exceeded, short-circuit isolators may trip and a fault will be reported at the
control panel. Commissioning
It is important that the Ancillary Base Sounder be fully tested after installation. A Test Set, part no.
55000-870, item no 204-0016, may be used to carry out functional testing of individual units. The test set
can also perform data integrity tests of an entire system.
