AL800ADA - Power Supply Board
Terminal Legend Function/Description
L, G, N Connect 120VAC to these terminals: L to hot, N to neutral.
- DC + 24VDC @ 8 amp in alarm non-power limited output.
Form "C" dry contacts indicate the loss of AC, with AC present terminals marked [NO and C]
AC FAIL
are open, [NC and C] are closed. When loss of AC occurs terminals marked [NO and C] are
NO, C, NC
closed, [NC and C] are open.
Form "C" dry contacts used to instantaneously signal the loss AC to local annunciation devices,
AC LOCAL
with AC present terminals marked [NO and C] are open, [NC and C] are closed. When loss of AC
NC, NO, C
occurs terminals marked [NO and C] are closed, [NC and C] are open.
Form "C" dry contacts indicate low battery voltage or loss of battery voltage. Under normal
BAT FAIL
conditions terminals marked [NO and C] are open, [NC and C] are closed. During a trouble
NO, C, NC
condition terminals marked [NO and C] are closed, and [NC and C] are open (Fig. 2, pg. 7).
+ BAT - Stand-by battery input (leads provided) (Fig. 2, pg. 7).
• AC Fail condition will report approximately 30 seconds after loss of AC. To delay report for 2.5 to 3 hours cut
jumper AC DELAY on the Power Supply Board (AC trouble output delay option). If this mode is selected the Power
Supply Board must be reset by removing all power to it for 30 seconds.
• Low battery condition will report at approximately 21VDC.
• Battery presence detection will report within 180 seconds after battery remains undetected (missing or removed).
A restored battery will report within 30 seconds.

will blink with a shorter and distinctly different duration. The green input LEDs will be off (normal condition).
To reset the memory depress the reset button located on the AL842LGK logic board (Fig. 2c, pg. 7).
The LED(s) will extinguish.
