Intelligent Base Sounder

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
