Spring-return actuator with 2-point control for safety damper

Joventa Security"s electric actuators have been specially designed for motorised operation of safety dampers for purposes such as fire protection, smoke protection and tight sealing. The actuator moves the damper to its normal operating position, closing the spring. Should the power supply to the actuator be interrupted, the stored energy in the spring will immediately move the damper to the safe position (damper close). The manual locking is cancelled automatically when the actuator is operated electrically. Key features: 2-point control; 2 adjustable auxiliary switches; 10/11/12/14 mm square shaft adapter; direct connection of thermal sensor ST 1.72 for duct interior temperature monitoring Ca 72?C; actuator thermal sensor for ambient temperature monitoring Ca 72?C; screw terminal connections; manual control by pushbutton; power saving at end stops; and customising available.
