ALS Minimum Level
The ALS minimum level is the lowest speaker output level that the station will maintain. To set the ALS
minimum level, turn R91 fully counterclockwise. Listen for a single beep from the speaker indicating the
speaker amplifier is in the Minimum Level Adjustment mode. If the page line is in use immediately after
the beep tone, the page signal should be used to make the minimum level adjustment. If the page line is
inactive following the beep tone, a continuous tone is activated to make the minimum level adjustment.
After the tone is activated, all page line activity is ignored until completion of the adjustment.
This test tone is used as a reference to adjust the speaker amplifier output level to the desired volume.
Adjust R91 to the desired output. The test tone automatically shuts off 5 seconds after the last
adjustment. The factory default setting for minimum level is 4.0 watts nominal into an 8-ohm load.
ALS Offset Level
The ALS offset level allows the output of the speaker amplifier to maintain a set difference or “offset”
between the ambient noise level and the speaker output level. To set the ALS offset level, turn R91 fully
clockwise and listen for the two beep tones indicating that the station is in the Offset Adjustment mode.
If the page line is in use immediately after the two beep tones are heard, the page signal should be used to
make the offset level adjustment. If the page line is inactive immediately following the beep tones, a
continuous tone is activated to make the offset level adjustment. After the tone is activated, all page line
activity is ignored until completion of the adjustment. Adjust R91 to the desired offset level.
N
OTE :
This adjustment should be made under maximum ambient noise level conditions. The ALS offset
level must always be set higher than the ALS minimum level setting.
SmartSeries VLC Level
When activated, the VLC overrides the ALS minimum level setting allowing the speaker volume to
change to a preset level during an emergency page. To adjust the VLC Level, force the station into the
VLC mode by having someone execute a page from a station programmed by the MCU to activate the
VLC function. During the page, turn the R91 control fully counterclockwise, and listen for two beep
tones through the page speaker indicating the VLC Adjustment mode has been activated. After the two
beep tones, turn the R91 control to the desired speaker level using the live paging signal to adjust the
level. The station automatically exits the VLC Adjustment mode and reverts to normal operation 5
seconds after the last pot adjustment.
N OTE : The system must be equipped with an ADVANCE head end to activate the VLC function.
