INSTALLATION

Before you begin, make sure that all of the cables and wires, as well as the power supply cable will reach the proposed location of the HT-MSU. Mark the cables with labels that describe where the cable originates (rather than which terminal on the HT-MSU it connects to).

STEPS:

1) CONNECT POWER TO THE HT-MSU. CHECK LED, DISCONNECT POWER

Plug the supplied 12V DC power supply into an unswitched AC outlet. Plug the connector into the socket marked “Power” on the HT-MSU. If the Power LED does not light, test the unswitched AC outlet with another appliance. If the outlet tests OK, you have a defective power supply, which must be replaced for you to continue. Once you have completed the power supply test, unplug the power supply and continue hooking up the rest of the

wires and cables.

2) CONNECT THE SENSOR CABLE TO IR INPUT

Strip 1/4 inch of the insulation from the end of each wire. Tightly twist the end of each wire until no frayed ends remain. Use a small flathead screwdriver or your fingernail to raise the locking tabs, exposing the holes on the removable connector. Insert each wire into the appropriate hole on the removable connector plug (Figure 8) and snap the locking tab down. To help you, the connector plug is keyed. Insert the smooth side of the connector plug into the smooth side of the socket.

3) CONNECT ALL FLASHERS

Route the connecting wire to the HT-MSU. Connect the 3.5mm mono plug into the corresponding SRC jack labeled “IR Output” from the installation worksheet.

If you need to extend the wire, use a 2-conductor 16

gauge or larger (SEE “TECH TIP ON PAGE 12).
