1. Set the device address.
1. Install the backbox.
2. Wire the ZP787-3.
3. Install the ZP787-3.
Setting the device address
The ZP787-3 includes a seven-segment DIP switch (SW1) for
assigning device addresses. Each switch segment represents
the value shown below. The address is the sum of all the
switch segments in the ON position. The switch is used to set
the device address in binary code. The switch may be set to
represent any address from 1 to 127 that is not used by
another device on the same loop.
For example, to select a device address of 007, set SW1-1,
SW1-2, and SW1-3 to the ON position and the remaining
switch segments to the OFF position.
