Advanced MXP-544 P-Bus 8-way Relay card

The Advanced MXP-544 is the Peripheral 8-Way Relay Card, an internal P-Bus module for the MxPro 5 MX-5000 range of fire alarm control panels. It provides eight configurable relay outputs.

The card is configured using a positive action sequence with its on-board push button and LED indicators, so it can be safely configured and inspected. Up to 16 cards can be connected to a panel, adding up to 128 SELV relay outputs. Cards are protocol independent.
