Description

The Remote Input Output Unit (RIO) is a flexible way of connecting digital inputs/outputs to the AlphaCom exchange. The devices can operate on point to point connections (RS 232) or on a multidrop bus (RS 485)

Each RIO unit has 8 inputs and 18 outputs. The outputs are connected to the relayboard MRBD. Each MRBD has 6 relays. If all 18 outputs are used, 3 MRBD boards are required. The RIO and the MRBD are interconnected with a cable included with the MRBD. The RIOs can be mounted away from the exchange room, thus reducing cabling. If response time is critical (<2sec), as in audio control, the internal RCIs and RCOs in the exchange should be used.

The RIO is used for:

• Distribution of remote control outputs (RCOs) from the AlphaCom exchange such as door opening, video camera control, additional call indications etc.
• Connection of technical alarm inputs (RCIs). The alarm inputs can be signals coming from temperature control devices, fire panels, burglar alarms etc. The AlphaCom itself provides 6 RCI (2 in ACM) inputs, this can be increased to 140 RCIs by using the maximum number of RIOs.
