Section 3 – System Wiring and Hookup
3–13
Transformer
Connect the 16.5VAC 40VA transformer to terminals 36 and 37, using #16AWG wire at 15
feet maximum to an unswitched 120 VAC outlet.
Do not use any other transformer since this may result in improper operation or damage to the
unit.
AC loss reporting delay time is programmable in 15-minute increments within the
programming sequence. If AC loss is detected then the panel will report the AC loss code
using the account number defined for partition #1.
Battery Backup
The RED (+) and BLACK (-) flying leads must be connected to a 12VDC 5AH GELL CELL, to
serve as backup power in the event of AC loss. A 12VDC 5AH GELL CELL battery provides
approximately 4 hours of backup. The system performs automatic battery test approximately
every 4 minutes, with a low battery level at about 11VDC. If low battery is detected then it
will be reported using the programmed low battery code using the account number defined
for partition #1. Battery backup requirements for a 24-hour backup will require various
backup battery capacities based on the amount of auxiliary power being used by the control
panel and auxiliary devices. The chart below summarizes the recommended backup battery
requirements based on the auxiliary power being used:
AUX POWER
REQUIRED BACKUP BATTERY
620mA
20AH
300mA
12AH
200mA
10AH
100mA
8AH
To determine the total auxiliary power being used, add the current requirements for all of
the external devices connected to the control panel (i.e., smoke detectors, keypads, multiplex
peripheral accessories, and zone expander boards). The power does not include the power
consumed by the control panel.
Keypad Mounting
Keypad mounting is identical for both the LED and LCD versions of each keypad. Differences
do occur between the XK-7 series (XK-7LC and XK-716) and XK-5 series (XK-5LC and XK-
516) Keypads. The XK-7LC and XK-716 Keypads can be surface mounted or flush mounted.
Keypad mounting procedures are provided below.
The XK-7LC LCD keypad contains an adjustment located behind the door of the keypad to vary
the intensity of the display.
