Motion Alarm Test
Test the motion alarm to ensure it activates when the platelet agitator motion stops. The alarm may not activate immediately,
depending on the motion alarm delay setting. If the alarm does not activate when it should, refer to
Troubleshooting.
Notes
• The motion alarm delay range is 10 - 600 seconds. When testing the alarm, be certain the set delay time has passed.
•
When the motion alarm is activated, the red LED on the motion alarm switch will flash.
• The motion alarm is muted when the alarm volume is turned fully counterclockwise.

Ensure the Alarm Volume is set to an audible level and the Alarm Delay is set to the
minimum delay (as noted by red rotational arrows).
2.

Test and Replace Motion Alarm Back-up Battery
The motion alarm system is powered by DC power, backed up by a rechargeable 9V NiMH battery. The battery charges when the
platelet agitator is connected to its external AC/DC power supply. In the event of a facility AC power failure, agitation would stop
and the battery will power the motion alarm.
