Installation Guide
General
This guide describes the installation of the following sounders
Part number
Comments
45681-265
installed with XP95 base attached by two M4 x 16 screws sup-
plied (base not supplied with sounder)
The sounders may be connected only to control panels which use either the XP95 or the Dis-
covery protocol.
Note: The Intelligent Base Sounder is Type A, ie, it is not suitable for outdoor use.
The Intelligent Base Sounder complies with the requirements of EN54–3 : 2001.
Mounting Instructions
The Base Sounder may be secured to a UK standard conduit box or surface mounted (provid-
ing there is access through the surface for cabling). If an XP95 base is to be attached, it will be
necessary to make all electrical connections, set the address, select the desired output and
master/slave con
fi
guration before securing the XP95 base to the sounder.
Wiring details, Part no. 45681-265
Note: The sounder is polarity sensitive (supply reversal protected) and will not function if wired
incorrectly.
Connect the loop cables to the sounder terminal block, observing polarity. The wiring terminals
accept solid or stranded cables up to 2.5mm².
Connect the wires from the sounder to the XP95 base terminals, red to L2 and black to L1 (Fig
1).
When using the sounder as a stand-alone unit, the cap (red cap part no 29600-256, white cap
part no 29600-257) will need to be secured with a 1.5mm hexagonal driver (part no 29600-095).
Replacement of installed sounders
Sounders, part no 45681-265, set as masters, may be used as a direct replacement of existing
sounders 45681-261.

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. If an XP95 test set is used to
test the sounder operation may be intermittent. To avoid this, operate the sounder and exit the
single address test.
Fault Finding
Problem
Possible
Cause
No response or missing
Incorrect address setting
Incorrect loop wiring
Too many sounders between isolators
Sounder fails to operate
Sounder set to slave with no associated master
Control panel has incorrect cause and effect programming
