Spring return actuator with integrated communication module

The ONE-X is a spring return actuator with integrated communication module designed to simply operate Rf-t fire dampers of all sizes, automatically or remotely. When powered, the actuator moves the damper blade to its stand-by position. When the power is interrupted or when the temperature in the duct exceeds 72°C, the internal armed spring brings the damper blade back into its safety position. The motor can be reset manually by using a standard 9V battery. The integrated communication module enables monitoring and remote control of the fire damper using a ZENiX controller. The status of the fire damper can be read over the bus, even when power is not connected to the fire damper. Three LEDs on the ONE-X indicate the status of the damper, bus communication, and any error messages. The ONE-X is available in two versions: 24 V and 230 V. As an option, connectors can be provided on the two bus cables and the power cable.
