Description, Specifications, Installation, Operation, and Service Manual
NOTE
:
• The microphone volume adjustment knob, labeled MIC GAIN, is located on
controller card front panel.
• Local PA overrides ALL siren functions activated either remotely or locally.
Relay Output (JP11)
The relay output is terminal block JP11, which is located at the bottom of the backplane
motherboard. Relay JP11 closes whenever a siren function is running. In PA mode, the
relay closes for approximately 30 seconds when the PTT button is released. The relay is
open while the MIC PTT button is pushed.

600 ohm Input/Output (JP12)
The 600 ohm input is at JP12 at the bottom of the backplane motherboard. Use JP12 to
make connections for activation and status monitoring of the unit over wire-lines. Also,
use this port to connect external audio sources to the amplification system. (See “Figure
14 UVIC Controller Backplane Motherboard I/O”.)
Remote Activation (JP14)
Terminal block JP14 at the bottom of the backplane motherboard is the Remote
Activation Inputs. Optionally, you can operate the UVIC controller by wired relays or
pushbuttons. Use terminal block JP14 for external interface equipment.
You can activate functions 1 through 7 by providing momentary, dry contact closure
between COM and the desired JP14 terminal. Shorting F1 to COM activates whatever
is programmed for code #1, shorting F2 to COM activates whatever is programmed for
code #2, and so on. A half second momentary contact duration is required.
To terminate an activated signal before it runs for the full duration, do the following:
provide a momentary contact closure between JP14 COM and F8 (RESET).
NOTE
: No matter how F8 is programmed, F8 is a master reset or a stop switch.
