Low Battery Alert
Battery Checking – Select this checkbox to set the unit to test the battery voltage (default is every
4 minutes). If the battery voltage is low when the battery test occurs, the unit will broadcast a short
alert tone. The factory default “low battery” threshold is 11.5 V. If a backup battery is not connected
to the Paging Module, do not enable the Battery Checking.
Alert Tone Volume – Selects the volume of the “low” alert tone as a fraction of the unit’s speaker
output level (50%, 75% or 100%). The factory default setting is 50%.
DTMF with Manual Switch Mode
Volume Level
– Select the speaker output level using the slide bar. The valid range is 4 mW to 8 W in
doubling increments (4 mW, 8 mW, 16 mW, etc.).
Automatic Level Adjust
– Enable this feature if steady high noise is sometimes present near the
speaker, but is not present continuously. With the ALA feature disabled, the speaker output volume will
follow the exact level setting on the volume control slide. This feature is enabled by selecting one of the
three available offset levels; 5 dB Offset, 10 dB Offset, or 15 dB Offset. The Offset Level is the level of
audio (measured as dB SPL) above the average ambient noise level, at which the speaker will broadcast.
The maximum audio output power attainable, with or without ALA enabled, is 8 watts.
N
OTE
: ALA can be used in a Feed-Thru configuration. If the Addressable Amplified Speakers are
programmed for Follow-Me operation, the Lead speaker will be programmed for ALA functionality and
the Slave speakers will not. They will follow the level of the Lead speaker. If the Addressable Amplified
Speakers are programmed for Individual Operation, both the Lead and the Slave speakers operate
independently and each can be programmed for ALA functionality.
