Keypad Connections
The keypads are connected to the control panel with four-conductor cable to terminals 13
through 16. Attach each keypad used within the system to the terminals as follows:
T13 Red ( + voltage)
T14 Green
T15 Yellow
T16 Black ( - voltage)
The following rules apply concerning keypad wiring using 22 AWG wire:
A) Maximum keypad wire runs shall not exceed 1500 feet (any single keypad).
B) Daisy chain sum of keypad runs shall not exceed 3000 feet. This is the sum of the
distances to all keypads from the control panel on one daisy chain branch. For example, if
one keypad is 750 feet from the panel and another keypad is 500 feet from the first keypad,
then this distance would equal 750 + (750 + 500) = 2000 feet. Note that rule A still applies.
C) Total sum of all single runs and daisy chains shall not exceed 4000 feet. Note that rules A
& B still apply. For example, if there were two single keypad wire runs each 1000 feet from
the control panel, plus the daisy chain example from rule B, the sum of these wire runs
would equal 4000 feet.
D) If any keypads are powered from sources other than the control panel, then a common
ground must be connected between terminal 16 and the ground (negative) of the external
power supply.
E) Keypad wires should be run avoiding sources of possible AC induction or interference
caused by other devices. For example, Electrical wiring, Computer wires, etc.
The available keypad power (from terminals 13 and 16) is restricted to 280 mA (250 mA for
UL applications). Each keypad draws approximately 70 mA and therefore a maximum of 4
keypads can obtain power from these connections. Additional keypads must obtain their
power from the other auxiliary panel outputs (if sufficient capacity is available) or an
external power supply.
All keypads must be connected to terminals 14 and 15 regardless of where they obtain power.
Keypad Addressing
Both versions of keypads (LED models XK-716 or XK-516 and LCD models XK-7LC or XK-
5LC) contain switches to set the address of the keypad. This address will identify the keypad
number to the control panel. In a partitioned system each keypad can be assigned to a
partition.
Within the control panel programming questions the LED keypads are known as keypads 1-8
and the LCD keypads are known as 9-16.
These switches are located under the cover at the bottom left of XK-516 and XK-5LC
keypads. To access the switches in the XK5LC and XK-516 keypads, remove the front of the
keypad from the keypad back by placing a straight-slot screwdriver into one of the two slots
in the bottom of the keypad and twisting the screwdriver. The switches are located behind
the pull open door and zone card for XK-716 and XK-7LC keypads. The switch positions for
the keypads are as as shown below:
