with AC present terminals marked NO and C are open, NC and C are closed . When loss of AC
NO, C, NC
occurs terminals marked NO and C are 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 used to signal low battery voltage or loss of battery voltage .
BAT FAIL
Under normal conditions terminals marked NO and C are open, NC and C are closed . During a
NO, C, NC
trouble condition terminals marked NO and C are closed, and NC and C are open (Fig. 2, pg. 9).

*Power Board Parameter Specifications:
• 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
