Mount the Enclosure
1. Determine the conduit or cable gland location(s) on the rear enclosure (see Figure 3).
NOTE: The drill spots provided on the outside of the enclosure do not line up with the center of the
holes that must be drilled in the enclosure to accept the conduit.
Figure 3. Ground Plate Hole Locations
2. Cut or punch the appropriate size hole(s) in the enclosure.
The ground plate accepts two conduits up to 1.75 inches in diameter.
3. Secure the rear enclosure to the wall with screws or appropriate fasteners.
The enclosure mounting holes are 0.280-inches in diameter.
4. Install conduit using Myers™ ST-4 (1.25-inch) Scru-Tite® hubs or equivalent.
Reducers must be used for smaller conduit sizes to ensure proper contact with the supplied grounding
plates. Hub(s) must be connected to the conduit before being connected to the enclosure.
Field Terminations
The SP2 to Page/Party® Bridge provides terminal blocks on the main PCBA located in the rear of the
enclosure for field wiring the power, 33-ohm Page/Party® audio lines, Ethernet, channel isolation inputs,
and contact outputs (see Figure 4)
Earth Ground
The bridge must be connected to earth ground.
1. Pull the power supply cable or a separate green/yellow sheathed ground cable into the enclosure.
2. Install a #6 ring lug on the ground conductor.
3. Secure the ground conductor to the CUSTOMER GROUND lug located in the bottom of the rear
enclosure (see Figure 2).

Page/Party® 33-Ohm Audio
Connections—P2
Terminal block P2 provides connections for
six, 33-ohm audio lines (typically one page
and five party lines). Connect the six
Page/Party®audio lines to the six, two-
position pluggable terminal blocks P2 as
follows:
1. Pull the Page/Party®system cable through
the conduit and into the enclosure.
2. Install ferrules onto the wire ends of each
page and party line audio pair.
3. Connect each audio pair to one of the
two-position terminal blocks (see Figure
4 and Table 2).
4. Connect the six P2 terminal blocks to the
terminal block receptacle P2 (see Figure
4).
60029 Series Page/Party® System Cable
Page/Party®stations should be connected using GAI-TRONICS 60029 Series system cable. Refer to
Table 3 for the Page/Party®system cable color codes:

Channel Isolation Inputs—P3
Channel isolation inputs independently isolate SP2
multicast channel audio from each of the six
Page/Party®audio lines. Activation of an input
disconnects the SP2 and Page/Party®audio signals in
the bridge for that audio channel. This prevents audio
from traversing the bridge to the receiving system.
Terminate the six channel isolation inputs to terminal
block P3 (see Figure 4). P3 is a 12-position terminal
block. Six, two-position terminal plugs are used; one
for each channel isolation input. Complete the
termination as follows:
1. Pull the cable(s) for the channel isolation inputs
through the conduit and into the enclosure.
2. Install ferrules onto the wire ends.
3. Connect each channel pair to the two-position
pluggable terminal block for that channel (see
Figure 4 and Table 4).
4. Plug the six two-position pluggable blocks into
terminal block P3.
Contact Outputs—P4
The SP2 to Page/Party®Bridge is equipped
with six contact outputs (see Figure 4).
Outputs become active when a digital audio
signal is detected on the associated SP2
audio channel. These outputs may then be
used to actuate field devices when SP2
page or party-lines go off-hook.
The outputs are terminated at terminal
block P4.P4 is an 18 position terminal
block. Three-position pluggable terminal
blocks are used for each output to simplify
the connection of the outputs:
1. Pull the cable(s) for the contact outputs
through the conduit and into the
enclosure.
2. Install ferrules onto the wire ends.
3. Connect each set of output contact
wires to the appropriate three position
pluggable terminal block (see Figure 4
and Table 5).
4. Connect each three-position pluggable
terminal block to terminal block P4.

Mute Connection—P5
The muting conductor of the Page/Party®system cable has no function in the SP2 to Page/Party®Bridge.
Terminal block P5 provides a dead ended termination for the muting conductor of the Page/Party®system
cable (see Figure 4):
1. Install a ferrule onto the end of the orange wire.
2. Connect the wire to pin one on pluggable terminal block P5.
3. Connect the pluggable terminal block to terminal block P5.
Power—P1
The SP2/Page/Party®Bridge operates from a 120/230 V
ac, 50/60 Hz power source. AC power is connected at
terminal block P1:
1. Pull the cable from the power source into the
enclosure.
2. Install ferrules onto the wire ends.
3. Connect the line, and neutral, conductors to the
pluggable terminal block (see Figure 4 and Table 6).
4. Connect the pluggable terminal block to terminal
block P1
Close the Enclosure
1. Reconnect the front cover to the rear enclosure by pushing the hinge pins on the front cover into the
holes on the left side of the rear enclosure until a click is heard.
2. Rotate the front cover to close the enclosure.
3. Install and tighten the four screws on the front cover.
Configuration
SP2 to Page/Party®Bridges are configured using the GUDA (GAI-TRONICS Universal Device
Application) software. Install the GUDA software and run it to configure Page/Party®bridges as follows:
1. Launch the GUDA application by double clicking the GAI-TRONICS Universal Device Application
shortcut from the start menu.
