CONNECT THE CABLE
You can use either a CAT5 cable or two shielded 22/4 cables for this installation. This guide uses a CAT5 cable. If
using shielded 22/4, you must connect the shield to the ground on each end.
The remote module can be installed up to 300
feet away from the control panel.
1. Connect one end of the CAT5 cable to the terminal on the panel module. See Figure
7.
Caution: Observe polarity and make sure wires are installed straight through.
2. Connect the other end of the CAT5 cable to the terminal on the remote module. See Figure
8.
3. Apply power to the system to turn it back on.
