INSTALLATION

When Installing this Product . . .

1. Read these instructions carefully. Failure to follow them could damage the product or cause a hazardous condition.

2. Check the rating given in the instructions and on the product to make sure the product is suitable for your application.

IMPORTANT

Be sure AZ1 and AZ2 wires do not cross and are a minimum of 12 in. from any line voltage wiring. If not possible, use shielded cable for AZ1 and AZ2 wires.

NOTE: Only two wires are required to connect the TAZ-4

panels to the main TZ-4 panel. Each TAZ-4 is wired in a daisy chain or parallel to each other, connecting the AZ1 and AZ2 terminals between panels.

Connect the AZ1 and AZ2 terminals on both panels using standard 18-gauge thermostat wire:

1. Connect AZ1 on the TotalZone panel to AZ1 on the Add-A-Zone panel.

2. Connect AZ2 on the TotalZone panel to AZ2 on the AddA-Zone panel.

SETUP

Each TAZ-4 panel has a set of five DIP switches. When using a TZ-4 and one TAZ-4, set DIP switches 1, 2, and 4 to off and switches 3 and 5 to on. Refer to Table 1 for other panel configurations. Identify the zones that are controlled by the TAZ-4 panel and set the DIP switches accordingly.

If the TAZ-4 is connected to a TZ-3 zone control panel, set DIP switches 1, 2, and 4 to off, and switches 3 and 5 to on. Set the switches on additional TAZ-1, TAZ-2, and TAZ-3, or TAZ-4 panels to control the zones they are wired to; but be careful that there is no duplication of zone numbers. See Table 1.
