• Description:

The RF relay has three connectors (common, NC (main) and NO (stby)). The unit can be hot wired to the alarm outputs from the radios, or controlled from a remote control unit. For maximum flexibility the input signals are optocouplers that covers a large voltage range. In addition, the control logic can be inverted. The unit’s several outputs can be used for monitoring the current status or controlling external units.
