TEST - ADVANCED ONLY

The VRF II Series provides a means for self-test using the magnetic FOB provided with the unit. When the unit 
is not in alarm, place and hold the FOB over the “TEST” label on the cover. If the unit is functioning properly, the 
unit will alarm according to the selected fail-safe mode 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
