Preliminary
Installation Features
The AMS-9050 controller provides the following
installation features:
- Auto Synchronization
- Wired Synchronization
- Transmitter Current Control
- Controller Mounting.
Auto Synchronization
Auto synchronization occurs during power up or
system reset. Auto sync can have different
outcomes depending on whether or not nearby
EAS transmitters are detected, they are properly
aligned to the ac-derived timing of the controller, or
too much ambient noise exists.
No transmitters detected. During initialization, the
controller determines if EAS transmitters are
nearby. If none are found, transmitter delay is set
to zero if this is the initial power on, or set to the
value stored in the controller if not the initial power
on.
Transmitters detected:
- Transmitters detected and aligned. If
transmitters are correctly aligned, the
transmitter delay is calculated and stored in the
controller for reference.
- Transmitters detected and not
aligned. If
transmitters are not aligned, the transmitter
delay is set to zero if this is the first power on of
the controller, or set according to the value
stored the controller if not the initial power on.
Too much ambient noise. During initialization, the
controller locates other nearby EAS transmitters.
- If ambient noise prevents the controller from
locating nearby EAS controllers and if this is the
first power on of the controller, transmitter delay
is set to zero.
- If this is not the first power on of the controller,
the zero crossing delay stored in the controller
is used.
Note: The controller stores the zero crossing delay
for when the controller could not determine a
reliable lock during subsequent power cycles.
Instead of using zero for the delay, the controller
uses the stored zero crossing delay.
Wired Synchronization
If a wired Tx sync device is connected to the
controller, the controller automatically uses its
signal as the timing reference instead of the ac
line. The service configurator indicates that wired
sync is active.
Transmitter Current Control
This function enables you to inhibit the transmitter
and/or alarms of the desired pedestal using the
Tx/Alarms inhibit switch located in the top of
antennas that support this function.
Controller Mounting
The controller has a built-in flange used to attach
the controller to a wall or ceiling using suitable
hardware.
- Ceiling attachment requires plywood be first
attached to the ceiling and then the controller
attached to the plywood.
- Structure and mounting hardware must support
25.6kg (56.5 lbs) or four times the weight of the
controller assembly.
