4.3.3 FAIL-SECURE MANUAL OPERATION
The FAIL-SECURE option locks the gate when primary (AC) power is removed and requires a keyed
release to place the gate in manual operation. The FAIL-SECURE option is typically used in CLASS
III and CLASS IV applications.
• Be sure that primary (AC) and backup (DC) power is removed or shut-off prior to placing the
gate operator in manual operation.
• Insert the manual release key into the keyed release on the side of the gate operator, and
turn it clockwise 1/4 turn. The gate can now be manually operated.
