the corresponding terminals on the panel.

2. Up to 3 keypads may be connected in parallel. DO NOT connect multiple keypads on the same loop.

3. The wiring table gives the maximum wire run for various gauges of wire. Wire run lenghts are calculated on the

maximum current drawn by the keypad (when all lights are ON).

4. For stand-by loading purposes, it is recommended that a current draw of 20 mA per keypad be used. This represents

the panel in a disarmed state with two zones in alarm.

Note: If two wires of the same gauge are paralleled, the run length can be doubled. For example, If eight 22AWG

wires (2 RED, 2 BLK, 2 YEL, 2 GRN) are run to the keypad, the run length would double from 540 feet (164.5 m) to

1080 feet (329 m).
