Maintenance
UltraVoice Indoor Controller (UVIC)
Maintenance
Service and maintenance should be performed by qualified personnel familiar
with the UVIC, associated controls, and power sources being used and in
conjunction with the authorities having jurisdiction.
The sound output of speakers is capable of causing permanent hearing
damage. Use adequate hearing protection and avoid excessive exposure.
Before servicing or maintaining, ensure that remote activation cannot occur
and disconnect power to the UVIC.
To prevent the speakers from sounding, always turn off the power to the
UVIC at the AC disconnect and remove any DC power being supplied before
inspecting or maintaining the speakers.
Control Unit Preventive Maintenance
Test the UVIC for proper operation at least once a month. A daily test at noon, curfew,
or other selected time is preferred. This not only enhances the usefulness of the UVIC
and verifies that it remains ready for use when needed; it also instills confidence in the
reliability of the system.
In order to minimize the potential for a failure, annual inspection and maintenance is
recommended.
General Maintenance
Checking Signal Operational
To check signal operational:
1. When checking for proper control module output, unplug the terminal strip
connectors to the speakers (at the bottom of the system motherboard) to eliminate
output from the speaker array.
2. Activate each of the signals and observe the signal indicators on the control module
and the amplifiers.
3. If desired, connect an oscilloscope or digital multimeter (DMM) to the amplifier
module output terminal strip to observe the amplifier output. This output should be at
least 67 V
RMS
during a signal if the amp is programmed to run at full power. To limit
sound output, plug in one amplifier at a time during this test.
4. Plug all of the amplifier terminal strip connectors to enable amplifier outputs.
Checking the Battery
To check the battery:
1. For the GUEST charger: The voltage of a fully charged set of batteries should be
approximately 27.2 Vdc, and charger current should be less than 2 amperes. The
charger is set for 27.2 +/- 0.1 Vdc at room temperature.
