Maintenance
The National Fire Protection Association (NFPA) National Fire Codes®:
NFPA 92A, and UL, require weekly self test for dedicated smoke control
equipment used in a smoke control system. The actuator was designed
such that no special cycling is required during long-term holding when
used as a fire damper. Cycling once a year is recommended as a safety
precaution for the fire control systems.

connect the ground lead for proper
protection of the actuator. Any other
connection such as phase-to-phase,
can damage the actuator.
