5.15 Optional UVLOC Connections and Wall Mounting
Refer to figure 5-9 for the UVLOC mounting hole locations. The UVLOC is typically
mounted on a wall approximately 5’ above the ground.
The UVLOC requires a CAT5 cable between the UVLOC and the interface board
(UVLOC-IM) in the UVIC. One to one connections are made with either the RJ45
terminations or a bare wire terminal block at each end. The interface board connects to
the UVIC motherboard using interface cable part number 1461655 as shown in Figure
5-9.
The UVLOC-IM mounting bracket attaches to the left side of the control cabinet using
two of the charger mounting studs and the intrusion switch mounting studs. Refer to
Figure 9.1 to view the UVLOC-IM bracket and PCB mounting detail.
The UVLOC should be labeled to ensure the operators will know what messages and
functions are available. Verify the UVLOC is labeled properly for the application.
5.16 External 24VDC Power Connections
If 24VDC battery power is required to run external devices, the UVIC has a large
connector available labeled JP6 (-) 24VDC (+) located behind the cover plate on the
right side of the amplifiers. This connector accepts bare stripped wire between 18-6
AWG. A straight blade screwdriver with a 3/32”-1/4” wide tip and a 4.5” max length must
be inserted in the connector’s square opening to open the round spring loaded wire
entry point.
The connector is rated for 50A. The combined load of the UVIC and the external 24VDC
load must not exceed 50A. Wire gauge and fusing must be selected appropriately for
the load.
5.17 600 Ohm I/O Connections
Control Connections
Terminal block JP12 at the bottom of the system motherboard is used for making
connections to 600 ohm balanced audio equipment such as a direct connection to an
SS2000D or other type of control and status monitoring equipment. To use the 600 ohm
input for control signal audio, a jumper must be placed across pins 2-3 of JP8. JP8 is
located on the main controller card. The 600 ohm input can receive audio for control
and audio amplification as well as transmit reports to an external unit.
Audio Connections
To use the 600 ohm input for audio from an external audio source, place a jumper
across pins 1-2 of JP8. R111 can be used to control the volume level when used in this
mode. A contact closure must be provided at JP15 pins 10 and 11 (PTT: Push To Talk)
