Jumper settings determine how the AB-124 will react under various
circumstances. These jumpers should be set to the desired configuration
before the AB-124 is installed. If you need to make changes to the jumper
settings, the AB-124 MUST BE DISCONNECTED from the system first.
Jumper setting functions explained:
Volume Preset
- This jumper determines how loud the keypad will be
when it is turned on. If the jumper is on pins 1 & 2, the volume will always
be set at the default level when the AB-124 is turned on. If the jumper is
on pins 2 & 3, the volume will be at the same level as it was before the
AB-124 was turned off.
Status
is active when the zone is on and audio is present. Status will go
dormant when audio is not present.
Status Active
- This jumper determines what happens when the status
becomes active. Typically, when status becomes dormant, Channel Vision
amplified keypads go into a ‘sleep’ mode which mutes the amplified
keypad. If the jumper is on pins 1 & 2 when status becomes active, the
AB-124 will remain off until the power button is pressed. If the jumper is
on pins 2 & 3 when the status becomes active, the AB-124 will return to its
previous state (either on or off).
Source Mode
- This jumper determines if the AB-124 will be used as a
multi-source keypad or a single-source keypad. If you are using the
keypad in a single source system, set the jumper on pins 1 & 2. If you are
using the keypad in a multi-source system, set the jumper on pins 2 & 3.

Balance
... The two potentiometers on the AB-124
adjust the volume levels of each speaker channel. Use
these to adjust the speaker balance in this zone.
Gasket
... The AB-124 is shipped with
a gasket. This allows you to adjust the
height and fit of a decorator trim plate.
Leave the gasket as is for a flush fit.
Remove the gasket to have the AB-124
stand above the plate.
Connectors
... To simplify installation,
the AB-124 has both 110 and RJ-45
inputs. Only one of the inputs should
be used at a time.
Connect the AB-124 as shown.
