Keypad Connection
The GSZ44 outputs are be controlled by the MR40 keypad and a Knoll RB8 remote control.
Only one MR40 keypad can be used in a zone.
Note: MR40 keypads are not designed for outdoor use, high humidity, high temperatures or any extremes.
The MR40 contains an almost all brand infrared repeater and most functions can be controlled by the Knoll RB8 remote control. RB8 commands can easily be stored in a learning remote.
The MR40 is connected to the GSZ44 with CAT5e or CAT6 wire. Each keypad needs to have a home run on one wire. Each room or zone has a unique IR
Note: It is very important to use a top quality RJ45 8/8 crimper tool. We strongly suggest using a cat 5 / RJ45 electronic tester to verify the wire conductors.
We recommend the T568A wiring method, which is shown below.
The functions of each wire connection are also shown.

Run CAT5 wire from the keypad location to the GSZ44 location for each keypad. It isn’t a bad idea to run a second cat5 wire run to each location to leave the installation more “future proof” and reliable. Leave an extra 1 m or 3 feet on each side to make it easier to work on. Add a RJ45 connector of the right type for the CAT5 wire you have selected (not all CAT5 wires are the same) and crimp the connector to the wire on each side. Plug the RJ45’s into the MR40 and correct GSZ44 ports.
