C.) SecureLinx MTC-TL1. See Figure 5.
The SecureLinx MTC-TL1 is designed to protect the low voltage lines for traffic control systems,
PTZ Cameras and other remote equipment and begins clamping at 7.5 volts. It also protects a
2-wire telephone line and begins clamping at 220 volts. The ground terminal should not be used
unless the wiring is done with shielded wire. In that case, connect the shields to the “GND”
terminals on the module.
1. Strip back the outer jackets of both the Signal and Telephone wires about 4 inches (See figure 5).
2. Strip the ends of the individual wires about 1/4 inch. The MTC-TL1 has special screw clamp
terminals that work with a range of wire sizes without lugs or tinning wires (See figure 3).
3. Connect the ground wire or shield wire to the “GND” terminal on the “Protected” side of the
module.
4. Connect the wires from the traffic signal controller to terminals 1-2, 4-5, 7-8 on the “Protected”
side of the module. Connect the telephone wires from the Central Office (CO) to terminals 9-10
on the “Protected” side of the module.
5. Connect the wires to the traffic signal equipment (lights) to terminals 1-2, 4-5, 7-8 on the
“Unprotected” side of the module. Connect the telephone wires from the modem to terminals
9-10 on the “Unprotected” side of the module.
6. Mount protector to a solid surface, like plywood. Drill a 3/32 hole for the #6 x 3/4 screw and
eyelets provided. (See figure 4). Attach screw and eyelet to wall and slide protector over screw
and tighten. Add second screw to bottom of protector.
