3. Product Overview
The POTTER PSN-106B is a 10 AMP, 6 NAC (Notification Appliance Circuit) power supply designed for fire alarm and security applications. It provides regulated and filtered power to connected devices.
Key Features:
- 10 Amp total output current.
- Six independently supervised Notification Appliance Circuits (NACs).
- Built-in battery charger for standby power.
- Fault monitoring and reporting capabilities.
4. Setup and Installation
4.1 Mounting the Unit
- Select a suitable location that is clean, dry, and free from excessive vibration or heat.
- Mount the power supply securely to a wall or other stable surface using appropriate fasteners. Ensure adequate ventilation around the unit.
4.2 Wiring Connections
Refer to the wiring diagram provided inside the unit's enclosure for specific connection points. All wiring must comply with NFPA 70 (National Electrical Code) and NFPA 72 (National Fire Alarm and Signaling Code).
- AC Power Input: Connect the main AC power source to the designated terminals. Ensure the power source matches the unit's voltage requirements.
- Battery Connections: Connect standby batteries to the battery terminals, observing correct polarity. Batteries are essential for maintaining power during AC failures.
- NAC Outputs: Connect notification appliances (horns, strobes, etc.) to the NAC terminals. Each NAC is supervised for open and short circuits.
- Auxiliary Outputs: Connect auxiliary devices requiring regulated power to the auxiliary power terminals.
- Trouble/Supervisory Relays: Connect these outputs to the main fire alarm control panel (FACP) for remote fault reporting.
5. Operating Instructions
5.1 Initial Power-Up

| BATTERY | Green (Steady) | Batteries are connected and fully charged. |
| BATTERY | Yellow (Flashing) | Batteries are charging. |
| TROUBLE | Yellow (Steady) | A fault condition exists (e.g., AC failure, battery fault, ground fault, NAC fault). |
| NAC 1-6 | Green (Steady) | NAC is active and supplying power. |
| NAC 1-6 | Yellow (Steady) | NAC fault detected (open or short circuit). |
6. Maintenance
Regular maintenance ensures the reliable operation of your PSN-106B power supply. All maintenance should be performed by qualified personnel.
- Monthly: Inspect the unit for any visible damage. Verify all status indicators are normal.
- Annually: Test battery voltage and capacity. Replace batteries as recommended by the manufacturer (typically every 3-5 years). Clean any dust accumulation from the enclosure and ventilation openings.
- Record Keeping: Maintain a log of all inspections, tests, and maintenance performed.
7. Troubleshooting
If the unit exhibits abnormal behavior, refer to the following table before contacting technical support.
| Problem | Possible Cause | Solution |
|---|---|---|
| AC POWER LED Off | No AC input power. | Check circuit breaker, power cord, and AC input terminals. |
| TROUBLE LED On | General fault condition. | Check other status LEDs for specific fault (e.g., battery, ground, NAC). |
| BATTERY LED Yellow (Steady) | Battery fault or low battery. | Check battery connections, voltage, and age. Replace if necessary. |
| NAC LED Yellow (Steady) | NAC open or short circuit. | Inspect wiring on the affected NAC for breaks or shorts. Verify end-of-line resistor. |
