General Information
Product Overview
The GAI-Tronics SP2 station is a modular industrial
multicast VoIP (Voice over Internet Protocol)
communication system. The standard Class I Div. 2
Fiber SP2 configuration is an indoor, multi-party,
handset/speaker amplifier station using ac power with
RTU control. They are constructed of cold rolled steel
with a gray or safety orange powder-coat finish. A
number of options are available to add to or modify
station capabilities (see the Features and Options
sections below).
SP2 stations connect to an Ethernet network so the loss
of a single station will not adversely affect the entire
system. Each station requires a 100 Mbps link to a
switch or router using fiber optic cable. Isolate SP2
network traffic from other network devices to ensure the
quality of SP2 audio. Properly configure network
switches and routers for IGMP (Internet Group
Management Protocol) snooping and multicast filtering.
Maximum cable runs between fiber SP2 stations and
network switches are determined by the type of fiber
optic cable used in the installation.

national, and international electrical codes. North America—Consult the
National Electrical Code (NFPA 70), Canadian Standards Association (CSA
22.1), and local codes for specific requirements regarding your installation.
Install Class 2 circuit wiring in accordance with the NEC.
This equipment is suitable for use in Class I Division 2 Groups A, B, C, and D, Class II Division 2
Groups F and G, Class III, OR non-hazardous locations only. Combinations of equipment in your system
are subject to investigation by the local authority at the time of installation.
WARNING
—EXPLOSION HAZARD—Do not disconnect equipment before removing
power and verifying the area is known to be non-hazardous. Averttissement—
Risque d’explosion—avant de déconnector l’equipment, couper le courant ou
s’assurer que l’emplacement est désigné non dangereux.

Approvals section of this manual. Such installation may cause a safety hazard
and consequent injury or property damage.
WARNING
—In 24 V dc systems: Do NOT operate this equipment from a battery charger
with the batteries disconnected. Most 24 V dc battery chargers have an
unloaded output of 35 to 45 volts that can quickly damage equipment designed
for 24 volts nominal. Do not allow the maximum battery voltage to exceed the
maximum specified input voltage.
WARNING
—Do not disconnect equipment while energized.
Ensure proper grounding to protective earthing.
Only trained, qualified, and competent personnel must install these enclosures. Installation must comply
with state and national regulations, as well as safety practices for this type of equipment.
ATTENTION
—This device requires an active laser component provided by the end installer.

Enclosure Mounting and Cable Entries
The mounting location must be flat and provide
proper clearance, rigidity, and strength to
support the enclosure and all contained
devices.
1. Mount the enclosure using the four 0.312-
inch (8 mm) diameter holes located on the
mounting flanges with ¼-inch (M6)
hardware (see Figure 2).
•The suggested mounting height for all
station enclosures is 48 inches (1219
mm) to the center of the bottom
mounting holes of the enclosure.
•SP2 stations are not supplied with
conduit or cable openings.
2. Remove the front panel.
3. Drill or punch entry openings in the rear
section of the enclosure (see Figure 2).
•The station is suitable for bottom
and/or top entry.
•Using 70-volt/100-volt line audio
requires bottom entry.
•Recommended: Bottom entry prevents
condensation that may form in the
conduit from dripping onto the
termination PCBA.
•The minimum material (spacing)
between entry holes is ½ inch (13
mm).
NOTE: Do not use top entry with 70V/100V
termination PCBA.

Open the Station
Complete the following steps to open the station:
1. Remove the four screws from the front panel and turn it to the left to expose the interior surfaces.
2. Keep the wiring and ribbon cables connected.
3. Mount the front panel to the holes on the left side of the rear enclosure using two of the screws just
removed.

Field Wiring and Configuration
The Class I Div. 2 fiber SP2 station provides terminal blocks on the termination PCBA, located in the rear
of the enclosure, for field wiring the power, speaker, and RTU connections. The main PCBA, mounted to
the back of the front panel, provides the 600-ohm audio connection. The fiber termination board,
mounted on top of the main PCBA, provides fiber optic termination for the Ethernet SFP transceiver.
NOTE: Consult the National Electrical Code (NFPA 70), Canadian Standards Association (CSA 22.1),
and local codes for the specific requirements regarding your installation. Install all equipment
without modification and according to the local and national codes. Class 2 circuit wiring must
be performed in accordance with the NEC.
Station Ground
The station enclosure must have an earth ground connection:
1. Install a #6 ring lug on the ground conductor.
2. Secure it to the ground terminal located in the lower left corner at the back of the rear enclosure (see
Figure 3).

(Optional 70V/100V Termination PCBA Similar)
Direct Speaker Connection and Jumper Settings
Terminal block TB1 provides termination for the station’s 8 or 16-ohm remote speaker(s).
1. Pull the speaker cable(s) into the enclosure.
2. Install spade lugs to the wires.
3. Connect the speaker wires to terminal block TB1 (see Table 1).
4. Torque the terminal block screws to 8–10 in·lb (0.90–1.13 N·m).
5. Configure the speaker jumpers, P2 and P3, for the appropriate impedance for use with 8-ohm or 16-
ohm speakers (see Figure 4 and Figure 5).
A redundant set of terminals enables connection of a second speaker branch connected in series or parallel
with the primary speaker.

70-V/100-V Termination Board Option—Speaker Connections with Monitoring
The optional 70-volt/100-volt speaker line-
monitoring PCBA replaces the standard
termination board and enables connection of
70-volt and/or 100-volt speakers to the SP2
station. Terminate the station’s speaker loop(s)
to terminal block TB1. Wire all speakers in
parallel. One speaker loop can be monitored by
terminating the return cable to the LINE SPRVN
terminals at terminal block TB2 (see Figure 6
and Table 2).
1. Pull the 70-volt and/or 100-volt speaker
cable(s) into the enclosure.
2. Install spade lugs on the wires.
3. Connect 100-volt speakers between the
100V and COM terminals on TB1.
Connect 70-volt speakers between the 70V
and COM terminals onTB1.
Two sets of terminals exist for the 70-volt
and 100-volt speaker loops, providing
termination for additional speaker loops.
NOTE: The station can only monitor one
speaker loop
4. For speaker line supervision, connect the
speaker return wires to the LINE SPRVN +
and − terminals at TB2 (see Table 4).
5. Move jumper P2 to pins 2–3 to enable
ground fault monitoring.
6. Torque the terminal block screws to 8–10
in·lb (0.90–1.13 N·m).
NOTE: The combined wattage (tap settings)
for all speakers must never exceed the
amplifier power rating (24 W).
