Overview
The patch panel supplies power to the alarm circuits connected to an AIC network module, by means of a -48V DC circuit bridged to the alarm circuit. Current flows when the loop is closed by an alarm. The network module detects this current and sends a message to the network operating center.
There are two models of AIC patch panel:
•
Product number AIC-SGL-PNL (see Figure 1, Figure 2, and Figure 3) connects to a single AIC network module. It provides an interface between a bank of four Telco 50-pin connectors (for the Telco side) and a bank of four 50-pin SCSI II connectors (for the network module side).
•
Product number AIC-DBL-PNL (see Figure 4, Figure 5, and Figure 6) connects to two AIC network modules. It provides an interface between two banks of four Telco 50-pin) connectors and two banks of four SCSI II connectors.
The AIC network module is shown in Figure 7.

Figure 10 Grounding Lug
Step 3
Strip one end of an AWG 6 copper wire to expose approximately 0.75 in. (20 mm).
Step 4
Place the wire in the lug. Using a Panduit CT-720 crimp tool with die set CD-720-2, or the equivalent, crimp the lug until the wire is firmly in place, as shown in Figure 11.
Figure 11 Crimping the Lug Around the Wire
Step 5
Fit the grounding lug over the bolt posts on top of the two inside 8-32 nuts.
Step 6
Hand tighten the outside 8-32 nuts on the bolt posts on top of the grounding lug (see Figure 10).
CautionDo not overtorque the outside 8-32 nuts. The recommended torque is 15 ± 18 inch-lb.
Step 7
Connect the other end of the wire to a suitable grounding point.
Connecting Electrical Power
This section explains how to connect electrical power to the patch panel.
The AIC-SGL-PNL patch panel provides terminals for eight analog circuits. Power is provided to each monitored circuit by the IN terminal block on the back of the patch panel. Power is taken from each monitored circuit by the OUT terminal block located below the IN terminal block.
The AIC-SGL-PNL patch panel must also have -48 VDC connected to the first pair of terminals (port 0) on the IN terminal block. This voltage is independent of other feeds being monitored and is used to operate the detection circuits. The 500 mA fuse for port 0 is shown in Figure 12.
The AIC-DBL-PNL patch panel does not provide monitoring of analog circuits. This patch panel must have -48 VDC connected to the terminal block on the back of the patch panel.
Follow this procedure to wire the terminal block:
Warning
Before connecting or disconnecting ground or power wires to the chassis, ensure that power is removed from the DC circuit. To ensure that all power is OFF, locate the circuit breaker on the panel board that services the DC circuit, switch the circuit breaker to the OFF position, and tape the switch handle of the circuit breaker in the OFF position. To see translations of the warnings that appear in this publication, refer to the Regulatory Compliance and Safety Information document that accompanied this device.
Step 1
Make sure that you have grounded the patch panel, as described in the"Grounding" section.
Step 2
Attach lugs to 14-AWG (1.5 mm2 cross section) copper wire or equivalent.
Step 3
If you are connecting an AIC-SGL-PNL patch panel, connect wires from the monitored analog circuits to terminal blocks 1 through 8 on the back panel. The BAT (negative) terminal is on the left and the RET (positive) terminal is on the right of each pair, as you look at the back of the patch panel. BAT and RET are also marked on the patch panel chassis. Labels identify the port numbers.
Step 4
Connect -48 VDC to port 0 on the back of the AIC-SGL-PNL patch panel, or to the terminal block on the back of the AIC-DBL-PNL patch panel. The BAT (negative) terminal is on the left and the RET (positive) terminal is on the right of each pair, as you look at the back of the patch panel. BAT and RET are also marked on the patch panel chassis. See Figure 12.
Figure 12 -48 VDC Connection
Warning
When stranded wiring is required, use approved wiring terminations, such as closed-loop or spade-type with upturned lugs. These terminations should be the appropriate size for the wires and should clamp both the insulation and conductor. To see translations of the warnings that appear in this publication, refer to the Regulatory Compliance and Safety Information document that accompanied this device.
CautionDo not overtorque the terminal block terminal block contact screws. The recommended torque is
8.2 ± 0.4 inch-lb.

To see translations of the warnings that appear in this publication, refer to the Regulatory Compliance and Safety Information document that accompanied this device.
Connecting Network Cables
Patch panel connections to the AIC network module are shown schematically in Figure 13. The four connectors of each AIC network module connect to four input connectors on the patch panel. The output connectors of the patch panel are cabled to the customer's main distribution frame (MDF). The patch panel looks transparent to the AIC network module.
An AIC network module provides four interfaces using 50-pin SCSI II receptacles. To connect the
SCSI II connectors on the front of the patch panel to the network module, use cables that have male Micro DB-50 connectors at both ends, with all conductors straight-wired. A set of four eight-foot male-to-male SCSI II interface cables is orderable separately, product number CAB-AIC-008. Ports are numbered from right to left and from bottom to top, as labeled on the module's rear panel (see Figure 7).To connect the Telco connectors on the back of the patch panel to the main distribution frame, use RJ-21 Telco connector serial cables (50-pin male).
Figure 14 shows connections from the AIC network module faceplate to a patch panel. Figure 15 shows connections to the AIC-SGL-PNL patch panel. Figure 16 shows connections to the AIC-DBL-PNL patch panel.
