The length of all wire runs must not exceed 1500 feet (457m) when unshielded quad conductor
cable is used (750 feet if shielded cable is used). This restriction is due to the capacitive effect
on
the data lines
when quad cable is used.

Mounting the Keypads
1. Make sure keypads are set to non-addressable mode (address 31), which is the factory
default setting. Refer to the instructions provided with the keypad for address setting
procedure.
2. Mount the keypads at a height that is convenient for the user. Refer to the instructions
provided with the keypad for mounting procedure.
You can either surface mount or flush mount keypads (using an appropriate Trim Ring Kit:
FA550TRK (except FA210KP, FA245KP). Refer to the mounting instructions and template
included with the keypad and/or trim ring kit for specific information.
Using a Supplementary Power Supply to Power Additional Keypads
The control provides 500mA for powering keypads (up to a maximum of 4) and other devices
from the auxiliary power output. The backup battery will supply power to these keypads in the
event that AC power is lost.
When the controlÕs auxiliary power load for all devices exceeds 500mA, you can power
additional keypads from a regulated, 12VDC power supply (e.g., 487-12 supplies 12V, 250mA;
488-12 supplies 12V, 500mA). Use a UL Listed, battery-backed supply for UL installations.
The 487-12/488-12 power supplies have a backup battery which can power these keypads in the
event of AC power loss.
Keypads powered from supplies which do not have a backup battery will not function when AC
power is lost. Therefore, be sure to power at least one keypad from the Control's auxiliary power
output.
