- Connect the AC power input to a dedicated, unswitched circuit as specified in the technical specifications.
- Connect the battery backup terminals to appropriate standby batteries (if applicable) to ensure continuous operation during power outages.
- Connect the NAC outputs to the notification appliances (horns, strobes, speakers) ensuring proper polarity and supervision.
- Connect the input from the fire alarm control panel (FACP) to the designated terminals.
4.4 Power-Up and Initial Test
After all wiring is complete and verified, apply AC power to the unit. Observe any status indicators for normal operation. Perform initial system tests as per the FACP manufacturer's instructions and relevant fire codes to ensure all connected NACs and appliances function correctly.
5. Operating Instructions
The SIMPLEX 4009-9201 NAC Extender operates in conjunction with a compatible fire alarm control panel (FACP). Its primary function is to receive signals from the FACP and activate connected notification appliances.
5.1 Normal Operation
Under normal conditions, the NAC Extender will be in a standby state, supervising its connected circuits. Status indicators (if present) should show a normal, non-alarm condition.
5.2 Alarm Activation
Upon receiving an alarm signal from the FACP, the NAC Extender will activate its connected notification appliances according to the programmed sequence (e.g., continuous, temporal 3, synchronized). The unit will continue to power the appliances until the alarm condition is cleared by the FACP.
5.3 Trouble Conditions
The NAC Extender continuously monitors its circuits for trouble conditions such as open circuits, short circuits, or ground faults. If a trouble condition is detected, the unit will typically send a signal back to the FACP, and a local trouble indicator may illuminate.
6. Maintenance
Regular maintenance is crucial for the reliable operation of the SIMPLEX 4009-9201 NAC Extender and the overall fire alarm system.
- Annual Inspection: Have a qualified technician inspect the unit annually as part of the overall fire alarm system inspection.
- Battery Check: If equipped with battery backup, check battery terminals for corrosion and test battery voltage and capacity regularly as per NFPA 72 guidelines. Replace batteries as needed.
- Cleaning: Keep the exterior of the unit clean and free of dust. Do not use abrasive cleaners or solvents.
- Wiring Integrity: Periodically check all wiring connections for tightness and signs of wear or damage.
7. Troubleshooting
This section provides basic troubleshooting steps for common issues. For complex problems, contact a qualified fire alarm technician.
| Problem | Possible Cause | Solution |
