800900 BSR - SAFETY BLOCK (BATTERY BACKUP)

The safety block is an automatic device which can be integrated into the actuator. It is composed of a battery pack and a PCB which ensure the return to the predetermined position (NC or NO) in case of power cut. This is not a single acting actuator but it follows the same principle.

BSR can ensure many operations in case of power cut. However, this option must be used as a safety device and not as a standard open/close operation. It is also recommended to permanently leave the actuator power on, in order to preserve its lifespan and the battery efficiency.

BSR is factory mounted and set, but it can be added on any actuator already in use.
