Adjusting the LCD Display
To adjust the viewing angle, remove the keypad from the back
mounting plate. Towards the bottom center of the circuit board is
a small hole. Insert a small screwdriver into the hole and adjust
R23, while holding the keypad at its mounting height. Adjust the
potentiometer as necessary for optimum viewing.
Addressing Keypads
Each Alpha keypad installed in the system must have an address.
Addresses must not be repeated. When replacing a keypad,
make sure the replacement keypad has the same address as the
previous keypad.
The first time you power up the system, unaddressed Alpha
keypads will display KEYPAD ADDRESS?. Press any number
from 0 through 7 at each keypad. The exact number you press is
not important as long as each keypad has a different address
number. The keypad will not accept values outside of the specified
range. Should you accidently use the same address for more than
one keypad, the system will fail to properly respond to the keypad
input. Refer to page 23 for assistance in correcting this problem.
Once all keypads have been addressed, reset the panel by
pressing [Master Combination] [*] [6] [8] [#] or by temporarily
removing both AC and DC power.
