Connecting A Secondary Wired Keypad

Ports 3, 4, and 5 are intended for use with a secondary wired keypad. The keypad may have an "A" pin, a "B" pin, and a ground. In that case, the "A" pin would be connected to port 3, the "B" pin to port 4, and the ground to port 5.

 

Connecting One Or More Wired Sensors Into A Zone

Ports 6 - 11 are intended for connecting a wired sensor (or a series of sensors on the same circuit) to the system. For example, to connect a sensor to Zone 1, you would connect the sensor's signal wire to port 6, and the sensor's ground wire to port 7.

If you have multiple wired sensors sharing the same circuit, then all of the sensors on the circuit would be added to the same Zone when connected.

 

Connecting An Antenna To Improve Cellular Signal

To connect a more powerful external antenna to the panel, connect the antenna's signal wire to port 15, and the antenna ground wire to port 14.

 

Powering Another Generic Device Through The Main Panel

The GSM panel can also provide power to another generic 2-wire device with a 12V connection. Use port 1 for power, and port 2 for the ground. 

 

For more information about connecting and using third-party sensors, please refer to the documentation for your third-party device(s).
