Advanced MXS-021 4-way Sounder Splitter card

The Advanced MXS-021 is a 4-way sounder splitter card for MxPro 4 control panels, supplied as the PCB only. It takes a standard sounder circuit from a control panel or other panel-based sounder circuit controller and splits it into up to 4 monitored outputs.

All 4 outputs operate together and follow the sounder circuit the card is connected to. Each circuit is fully monitored for open and short circuit, and the card can take an independent supply to provide up to 1A per circuit. Without an independent supply, the output load is limited to the sounder output loading of the input circuit.

Key features

• 4 monitored sounder outputs
• Up to 1A per circuit with an independent supply
• Open and short circuit monitoring on each output
• Red sounder and yellow fault LED for each output
• Cost effective against ancillary hardware
• 3-year warranty as standard

Technical specifications

• Sounder input: IN+/IN- to the panel sounder output; OUT+/OUT- to the rest of the circuit or a 10kΩ EOL resistor
• On-board indication: 4 red sounder LEDs (output triggered), 4 yellow fault LEDs (short or open circuit)
• Outputs, powered from input circuit: 4 monitored sounder circuits, 1A total maximum across all circuits; card current 25mA quiescent, 50mA driving
• Outputs, with external 24V DC 4A supply: 4 x 1A monitored sounder circuits; card current 30mA quiescent, 55mA driving
• Compatibility: All MxPro 4 control panels
• Supplied: PCB only
