TEST - ADVANCED MODEL
The LP II provides a means for self-test using the magnetic FOB provided with the unit. When the unit is not in material
(rod vibrating) place and hold the FOB over the “TEST” label on the cover. If the unit is functioning properly, the alarm LED
and main relay will change the state as shown below. When the test is completed and results verified, simply move the
FOB away from the unit.
HIGH FAIL-SAFE:
• Main relay de-energizes
• Red ALARM LED is on
LOW FAIL-SAFE
• Main relay energizes
• Red ALARM LED is off
