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.
Volume Adjust Address – Enter the DTMF Address code to be used for making volume changes from
a remote touch-tone device. The address should be a code unique to the unit being programmed. This
address code may include digits 0–9 as well as the extended DTMF digits A, B, C, and D. It can contain
two to eight digits. By using one or more of the DTMF digits A, B, C, or D, broadcast access will be
restricted to equipment capable of generating these DTMF digits, providing additional access security.
Test Tone Duration Adjust – The speaker will generate a tone at the current volume setting when it
enters the test tone mode (volume control). This entry starts the duration of the test tone. When the
volume is adjusted (in test tone mode), the speaker will generate a tone at the newly selected level. The
test tone duration’s valid range is 0.5–6.0 seconds in 0.5-second increments with a default setting of 3.0
seconds.
Output Contact – These settings control the activation of the Addressable Amplified Speaker’s contact
closure output. The settings are in effect only when the paging module is activated. Use the pull-down
menu to make one of the following selections:
 No Change – The output contact will be unaffected when the corresponding DTMF address is
received.
 Activate – The output contact will change state when the input control contact is received and the
module becomes active. The output contact returns to the normal state when the input contact opens.
 Activate + Hold – The output contact will change state when the input control contact is received.
The output contact returns to the normal state after the input contact opens and the Hold Time
duration expires.
Use the slide bar to set the Hold Time. Valid range is 1 second to 30 minutes.
Using the radio button, select the normal state of the relay contact with power applied to the paging
module. When power is removed, the contact will always be in the OPEN state.
 Normally Open – relay contact is OPEN when the unit is inactive and CLOSED when active.
 Normally Closed – relay contact is CLOSED when the unit is inactive and OPEN when active.
