Auxiliary Device Current Draw Worksheet

** If you are using devices such as PIRs, smoke detectors, etc., refer to the specifications for
that particular device's current draw. If the total current draw exceeds 500mA, use an
additional power supply.
*** For UL installations, do not exceed 180 mA.
NFPA, UL, and the California State Fire Marshal require the backup battery to provide power for
24 hours. The maximum aux. power varies by the ampere/hour rating of the battery used:
5AH = 95mA; 7AH = 180mA; 8AH = 210mA.
The control panel has four built-in programmable trigger outputs. In
addition, up to four XL4705 Relay Modules can be connected, providing 20
additional programmable relay outputs. If the Relay Modules are used
(enable modules in Question 17, 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 questions 37-48 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 (3 & 4 when not 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.
