The Responder Relay Module (RRM) is an optional add-on board to an ADR. When added the responder the combination is referred to as an Advanced Relay Responder (ARR). The RRM provides four relay outputs, which may be individually configured as supervised or not.
The RRM provides a current limited 24V output (100mA), which may be used to power external equipment, as long as it is wired through NO relay contacts.
The RRM must be used on ADRs with software versions V1.01 or greater, to provide RRM present monitoring.
