Potter Electric PSN-64 Nac Power Supply 6 Amp 4 Output

Product Description

The POTTER ELECTRIC SIGNAL CO. US PSN-64 is a Notification Appliance Circuit (NAC) power supply designed to expand and boost signaling capacity in fire alarm systems. Rated at 6 amps total output across 4 independent NAC outputs, this unit provides supplemental power to notification appliances such as horns, strobes, and horn-strobe combos. It is installed by licensed fire alarm technicians in commercial and light industrial applications where the main fire alarm control panel lacks sufficient NAC current capacity to drive all required notification devices. Each output circuit operates independently, supporting synchronized or non-synchronized signaling depending on system configuration.

The PSN-64 is used in commercial fire alarm installations where NAC expander capability is required. It connects to a host fire alarm control panel and delivers reliable supervised power to notification appliance circuits throughout the protected building. Typical applications include multi-zone office buildings, schools, healthcare facilities, and other commercial structures requiring code-compliant notification appliance coverage beyond the native output capacity of the primary panel. Installation falls under NFPA 72 requirements and must be performed by qualified fire alarm service personnel.

Installation Notes

Installation must be performed by a licensed fire alarm technician in accordance with NFPA 72 and applicable local codes. Disconnect and lock out all AC power and disable the host fire alarm control panel before wiring NAC output connections. Verify supervisory end-of-line resistor values match system requirements before commissioning. Do not energize the unit until all wiring connections have been inspected and the system has been tested per the authority having jurisdiction.
