Overview:
Bosch DSRF 2 Channel Relay Output Receiver (HCR-BU2)
The HCR-BU2 receiver is designed to provide relay outputs that 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.
