Electronic Fusible Link (EFL) ASK791.165 (165°F [74°C] operation) ASK791.212 (212°F [100°C] operation) ASK791.250 (250°F [121°C] operation) Operation When power is applied, the actuator coupling moves toward the open position, 90°. The actuator opens in 30 seconds nominal, 90° at 60 Hz. In the event of a power failure or when operating voltage is turned off, the actuator returns to the 0 position. The return time is 15 seconds (maximum) for 90°. The National Fire Protection Association NFPA 92A Standard for Recommended Practice for Smoke-Control System and UL 864 Standard for Control Units and Accessories for Fire Alarm Systems, require weekly self-tests for dedicated smoke control equipment used in a smoke control system. The National Fire Protection Association NFPA 72 Standard for National Fire Alarm Codes states that all life-safety systems are to be functionally checked at least annually. The GJD actuator does not require any periodic cycling to function properly as an integral part of an active smoke control damper system. Check the smoke control damper/actuator every time you functionally check your smoke detectors, emergency lights, and/or power generators for operation.
