## Discrepancy

WHEN EMERGENCY LIGHTS ARE IN ARMED POSITION, ALL EMERGENCY LIGHTS ILLUMINATE. THEN AFTER A FEW MINUTES ALL LIGHTS START TO FLASH.   SET BATTERY SWITCH TO ARM POSITION. EMERGENCY LIGHTS ILLUMINATED FOR ABOUT ONE MINUTE, FLASHED THEN EXTINGUISHED. CHARGED BATTERIES FOR 30 MINUTES. WITH BATTERIES OFF, SWITCH TO ARM, LIGHTS ILLUMINATED FOR 10 MINUTES WITH NO OTHER DEFECTS NOTED AT THIS TIME. POWER WAS APPLIED AND SWITCH SET BACK TO ARM TO CHARGE FOR ANOTHER 30 MINUTES, TESTED AGAIN WITH NO DEFECTS NOTED AT THIS TIME. ALL WORK WAS PERFORMED IAW MM 33-52-00
