Disabling IR Sensor 
An IR sensor on the front of the keypad allows operation of the system from a handheld remote control aimed at the keypad. This sensor can be disabled. Generally, the sensor only needs to be disabled when two keypads are installed in the same room. In this case, disable the sensor on the second keypad to prevent sending IR commands to both keypads. For the same reason, you might disable the sensor of a keypad installed near the components being controlled.
SW9 configures the sensor mode:
To enable the IR sensor, put SW9 in the ON position.
To disable the IR sensor, put SW9 in the OFF position.
NOTE: Learning commands is done by aiming a handheld remote at the keypad sensor. The sensor must be enabled during Learning configuration.
