DB992IVAS 990 Series Base Sounder/Visual Indicator With Isolator

Tone and Volume Selecteion

The DB992IVAS offers a choice of 15 evacuation and 15 alert tones.
Two tones may be selected during installation, one for evacuation and
one for alert. Volume levels may be selected during commissioning to
one of 7 pre-set levels, with output ranging from 60 dB(A) to 90 dB(A).
The low volume range is useful in areas such as hospitals where the
alert is initially intended to warn staff only.

During commissioning the sounder volume can be adjusted on location
without disassembly or removal. With the CIE in "setup" mode, the
commissioning engineer is able to adjust the volume using a magnetic
wand. Once all sounders have been adjusted, "setup" mode on the
CIE is cancelled and all sounder volume levels are stored in the
sounder.

Group Addressing and Control

When multiple sounder/beacons in an area always need to be
activated simultaneously, the DB992IVAS group addressing can be
stored in each device, allowing the CIE to activate the group with a
single command.

The installation also has free selection from the CIE on use of sounder
only, beacon only or combined sounder/beacon operation.
Functionality can be changed during time schedules, or time delays as
is required per individual location.
