Section 2. System Wiring and Hookup
2-5
BACKUP BATTERY:
The RED (+) and BLACK (–) flying leads must be connected to a 12VDC 4–7AH
lead acid battery, to serve as backup power in the event of AC loss.
A battery test occurs approximately every minute. Low-battery condition occurs at nominal 11VDC.
The keypad AC/LOW BAT LED and buzzer will pulse slowly when a low-battery condition is
detected. The system reports this condition to the CS if programmed to do so. There is also an
option that prevents the system from arming if a low battery has been detected (see Question 11,
L2). Battery restoral will occur within 4 minutes, at the next battery test. The buzzer may be
silenced by entry of any valid user code.
NOTE: For UL installations, use two 4AH batteries connected in parallel.
TRIGGER/RELAY OUTPUTS:
The control panel has four built-in programmable trigger outputs. In
addition, up to two XL4705 Relay Modules can be connected, providing 10 additional programmable
relay outputs. If the Relay Modules are used (enable modules in Programming Submode 1, Question
09, L2), then built-in triggers 3 and 4 are no longer used as trigger outputs, but serve as clock and
data inputs for the relay modules. See Programming Submode 1, Questions 23
–
29, for valid
trigger/relay types and programming.
NOTE: In order to connect devices to the triggers, use connector XL4612TC (trigger cable). Connect
to terminal P1 VBELL to obtain a POSITIVE reference point
.
Triggers 1, 2, 3, and 4 (only 1 and 2
when using XL4705) will go to a negative ground potential when active. For UL installations, the
trigger outputs shall be connected to devices rated to operate over the range from 10.1
–
14.0VDC at
50mA.

** If the system is
using devices such as
PIR's, smoke
detectors, etc., refer
to the specifications
for that particular
device's current draw.
If the total current
draw for all devices
exceeds 500mA, use
an additional power
supply.
*** For UL
installations, do not
exceed 180mA.
NFPA, UL, and the California State Fire Marshal require the backup battery to provide power
for 24 hours. The maximum aux. power will vary by the ampere/hour rating of the battery used:
5AH = 95mA; 7AH = 180mA; 8AH = 210mA.
