How does the BUS bar on the Total Security WiFi panel work?

The Total Security WiFi panel has a BUS bar consisting of 5 ports: two ports for a land line phone connection (labeled "TEL"), and 3 ports for wired sensors: 51, GND, and 52. The ground port labeled "GND" is shared between both Zones.

You can connect any existing wired sensors you may have to these ports, and then if any wired sensor is triggered, either Zone 51 or Zone 52 will be triggered in the system. To connect a 2-wire circuit, put the signal wire into one of the numbered ports, and put the ground wire into the GND port. Your wired sensors will need to have their own separate power source.

More than one sensor can be wired on the same circuit, and all sensors on the same wire will share the same Zone number.

There is no programming required for wired zones. Simply connect the wires to the BUS bar in the back, and then the wired sensors are ready to use. 

NOTE: We have two similar systems, the Total Security and the Total Security WiFi. If your system does not include the 2 ports labeled TEL, then you have a Total Security panel instead. We have a separate article for the Total Security BUS bar, located here.
