The HCR-BU2 receiver is designed to provide relay outputs which can be operated from any of the DSRF™ transmission type keyfobs supplied by Bosch Security Systems. These keyfobs are The RF3334, RF-HCT4UL-FOB and the Radion™ Keyfob FB.
This receiver removes the need to wire from the control panel to an external device such as a garage door or gate to operate the device. The HCR-BU2 can be powered from 12 to 24V AC or DC.
The product is supplied as a PCB only with no housing. This allows installation into gate motor housings etc.
This product is available through your local Bosch Security Systems distributor.
