2. Safety Information
Read all instructions carefully before installation and operation. Failure to follow these instructions may result in property damage, serious injury, or death.
- Installation must be performed by qualified personnel in accordance with all national and local codes and standards, including NFPA 72.
- Disconnect all power to the fire alarm control panel (FACP) or power supply before wiring.
- Ensure proper polarity when connecting wiring to avoid damage to the device.
- Do not paint over the device, as this may impair its functionality.
- Test the device regularly as part of a comprehensive fire alarm system maintenance plan.
- This device is intended for indoor use only.
3. Setup & Installation
3.1 Mounting
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.
- Select a suitable mounting location on a wall or ceiling.
- Prepare the electrical box or mounting surface according to standard practices.
- Secure the device's mounting plate (if applicable) to the electrical box or surface.
- Ensure the device is securely fastened and flush with the mounting surface.
3.2 Wiring
Wiring must be performed with power disconnected from the FACP. The GX93-W supports 12 AWG to 18 AWG wires. Observe proper polarity.
- Connect the positive (+) wire from the FACP or power supply to the positive terminal on the GX93-W.
- Connect the negative (-) wire from the FACP or power supply to the negative terminal on the GX93-W.
- If using a synchronization module (e.g., Gentex GX91/GX93), refer to the synchronization module's manual for specific wiring instructions.
- Ensure all connections are secure and properly insulated.
3.3 Voltage 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. Operation
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.
- Continuous Tone: A steady, uninterrupted audible signal.
- Synchronization: If connected to a compatible synchronization module, multiple GX93 Series horns will activate in a synchronized pattern.
5. Maintenance
Regular maintenance ensures the continued reliable operation of your GX93-W mini-horn.
- Cleaning: Periodically clean the exterior of the device with a soft, dry cloth to remove dust and debris. Do not use abrasive cleaners or solvents.
- Testing: 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.
- Do Not Disassemble: Do not attempt to disassemble or repair the device. Refer all servicing to qualified personnel.
6. Troubleshooting
If the GX93-W mini-horn is not functioning as expected, consider the following:
- No Sound:
- 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.
- Confirm correct voltage 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.
- Intermittent Operation:
- Inspect wiring for loose connections or damaged insulation.
- Check for voltage fluctuations from the power source.
If issues persist after troubleshooting, contact qualified fire alarm service personnel.
