3. Configuration et installation

3.1 Montage

The GX93-W mini-horn is designed for flush mounting on walls or ceilings. Ensure the mounting location is clean, dry, and free from obstructions. The device should be mounted in accordance with local building codes and NFPA 72 requirements for audible signaling devices.

1. Select a suitable mounting location on a wall or ceiling.
2. Prepare the electrical box or mounting surface according to standard practices.
3. Secure the device's mounting plate (if applicable) to the electrical box or surface.
4. Ensure the device is securely fastened and flush with the mounting surface.

3.2 Câblage

Wiring must be performed with power disconnected from the FACP. The GX93-W supports 12 AWG to 18 AWG wires. Observe proper polarity.

1. Connect the positive (+) wire from the FACP or power supply to the positive terminal on the GX93-W.
2. Connect the negative (-) wire from the FACP or power supply to the negative terminal on the GX93-W.
3. If using a synchronization module (e.g., Gentex GX91/GX93), refer to the synchronization module's manual for specific wiring instructions.
4. Assurez-vous que toutes les connexions sont sécurisées et correctement isolées.

Vol 3.3tage and Tone Selection

The GX93-W allows for field selection of operating voltage (12VDC or 24VDC) and tone type (temporal or continuous). Consult the device's internal jumpers or switches for configuration. Refer to the markings on the device for specific settings.

4. Fonctionnement

The Gentex GX93-W mini-horn functions as an audible signaling device within a supervised fire alarm system. When activated by the FACP, it will emit an audible tone according to its configured settings (temporal or continuous).

• Temporal 3 Tone: This is a specific pattern of three short bursts followed by a pause, commonly used for fire evacuation signals. Note that the sound output rating for temporal 3 tone is averaged, meaning the peak sound pressure during the tone burst is higher than the stated average.
• Son continu : A steady, uninterrupted audible signal.
• Synchronisation: If connected to a compatible synchronization module, multiple GX93 Series horns will activate in a synchronized pattern.

5. Entretien

Regular maintenance ensures the continued reliable operation of your GX93-W mini-horn.

• Nettoyage: Periodically clean the exterior of the device with a soft, dry cloth to remove dust and debris. Do not use abrasive cleaners or solvents.
• Essai: The mini-horn should be tested regularly as part of the overall fire alarm system testing protocol, as required by NFPA 72 and local authorities.
• Inspection: Visually inspect the device for any signs of damage, discoloration, or loose connections.
• Ne pas démonter : Ne tentez pas de démonter ni de réparer l'appareil. Confiez toute intervention à un personnel qualifié.

6. Dépannage

If the GX93-W mini-horn is not functioning as expected, consider the following:

• Pas de son :
  • Check power supply to the FACP and the device.
  • Verify wiring connections for proper polarity and secure contact.
  • Ensure the FACP is activating the signaling circuit.
  • Confirmer vol correcttage selection (12VDC or 24VDC) matches the power supply.
• Incorrect Tone:
  • Verify the tone selection settings (temporal or continuous) on the device.
  • If using a synchronization module, ensure it is correctly configured and functioning.
• Fonctionnement intermittent :
  • Vérifiez le câblage pour détecter les connexions desserrées ou l'isolation endommagée.
  • Vérifiez le voltage fluctuations from the power source.

If issues persist after troubleshooting, contact qualified fire alarm service personnel.
