Altronix 6.5A NAC EXTENDER 4 CLASS A/B - AL642ULADA

Altronix AL642ULADA 6.5A NAC EXTENDER 4 CLASS A/B

Overview

The Altronix AL642ULADA is a 6.5A notification appliance circuit (NAC) extender designed to expand the reach of fire alarm control panels (FACPs). This unit allows you to add up to four additional Class A or Class B NAC outputs, providing the necessary current to power a larger number of strobes, horns, or other signaling devices. It's critical for installations where the FACP's built-in NACs lack the required amperage or circuit count for full coverage. The AL642ULADA ensures compliance by providing supervised outputs, maintaining system integrity.

Compatibility

This power extender is compatible with most UL-listed fire alarm control panels that provide a 24VDC NAC output. It is designed to work with standard fire alarm systems requiring supervised notification appliance circuits. Specific compatibility should be verified against the FACPs installation manual and local code requirements. It integrates seamlessly with systems needing to power additional strobes, speakers, or combination devices.

Installation Notes

The AL642ULADA requires a 24VDC input from the FACP's NAC circuit, which it then boosts and extends. It provides four independently selectable Class A or Class B outputs. Wiring must adhere to NFPA 72 and local code requirements. Ensure proper supervision is maintained by connecting the unit's input to the FACP's NAC and utilizing the FACP's end-of-line resistors (or equivalent supervision method) on the extender's outputs. The unit requires a minimum 24VDC input and provides up to 6.5A total output current.
