4 Sounders - Disable & Assign
4-1 Sounder Configuration
Allows selection of PRESET or PROGRAMMED sounder operation.
Selecting PRESET (the default) will result in all sounders being operated; any Sounder Group settings will
be ignored.
4-2 Configure Sounder Groups
Allows all the Sounder Groups to be defined. A Sounder Group can consist of any combination of
sounders. 512 Sounder Groups can be defined.
For each sounder:
‘C’ indicates continuous operation.
‘S’ indicates silent (no) operation.
‘P’ indicates pulsing operation.
Panel 00 is the Panel and corresponding Conventional Sounder outputs.
Panel 01 corresponds to the Loop Sounders in the loop.
Group 512 is the Common Sounder Group. This is always operated when Sounder Group operation is
turned on and a fire occurs.
When a fire occurs all the Sounder Group information for the detector in fire is combined: the device
Sounder Group is combined with the Zone Sounder Group and the Common Sounder Group. ‘P’ pulsing
will override ‘S’ silent and ‘C’ will override ‘P’ pulsing.
When a subsequent fire occurs the new Sounder Group information is added to the existing Sounder
Group information. ‘P’ pulsing will override ‘S’ silent and ‘C’ will override ‘P’ pulsing.

CONTENTS
If Sounder Groups are defined then it is essential to set 4-1 Sounder Configuration to
PROGRAMMED, otherwise, all the system sounders will be activated by any fire event.
Individual detectors can be set not to activate Common Sounder Groups, Zone Sounder
Groups or all sounders. See function 4-5 Inhibit Sounders for Device.
If evacuate is operated (by setting CALL-POINTs to evacuate, then activating a
CALL-POINT, for example) the sounders will operate as if the sounder configuration were
set to PRESET.
NOTE:
The Sounder Groups must be defined when PROGRAMMED is selected because the
default group settings have all sounders set to silent.
PRESET or PROGRAMMED does not affect any sounder delay settings.
