Features The brushless DC motor ensures accurate speed control, torque monitoring for protecting the actuator and the damper, and provides a reliable failsafe function. In the case of a power failure, the mechanical spring ensures the failsafe function. Use For the control of fire and smoke protection dampers. ● Nominal torque of 9 Nm for damper surfaces up to about 1.

Temperature monitoring unit Use The temperature monitoring unit is ready connected to the actuator and is used for forced control of motorized fire and smoke protection dampers, should excessive temperatures occur. Mode of operation The temperature monitoring unit contains 2 thermal fuses, 1 for monitoring the duct temperature and 1 for the ambient temperature. If the temperature at any of these fuses exceeds the level of 72 °C (optionally: 95 °C), the power supply will be irreversibly cut.

Notes Safety Caution National safety regulations Failure to comply with national safety regulations may result in personal injury and property damage. ● Observe national provisions and comply with the appropriate safety regulations. ● Mounting, commissioning, and service by properly trained personnel only. Engineering WARNING Power supply The actuator must be used with safety extra low voltage (SELV) or protection by extra low voltage (PELV) in accordance with HD384.

Mounting bracket / pin If the actuator is mounted directly on the damper shaft, the mounting bracket/pin must be used. The insertion depth for the shaft into the housing must be sufficient. Temperature monitoring unit The temperature monitoring unit is to be fitted to the duct wall or the damper housing using 2 self-tapping screws of 3.5 mm diameter. The enclosed drilling template facilitates mounting. When mounting, it must be ensured that the thermal fuse is fully exposed to the airflow.
