This image displays the ECCO SA917N Back Up Alarm. It is a compact, black, horn-shaped device designed for vehicle safety. The front features a speaker covered by a grill, with a prominent blue label indicating 'ECCO SMART ALARM'. Two electrical wires, one red and one black, extend from the side for connection.
3. Setup and Installation
Proper installation is crucial for the optimal performance and safety of your ECCO SA917N Back Up Alarm. It is recommended that installation be performed by a qualified technician.
3.1 Mounting
- Select a mounting location at the rear of the vehicle that is protected from direct impact and excessive debris, yet allows for clear sound propagation.
- Ensure the mounting surface is flat and secure. The alarm is designed for reverse speaker mounting, meaning the speaker opening should face the direction of sound projection.
- Use appropriate fasteners (not included) to securely attach the alarm to the vehicle chassis or bumper. The Fiberglass Reinforced Nylon housing provides durability.
3.2 Wiring
- Identify the vehicle's reverse light circuit. This circuit typically provides power only when the vehicle is in reverse gear.
- Connect the red wire of the alarm to the positive (+) lead of the reverse light circuit.
- Connect the black wire of the alarm to a suitable vehicle ground (-).
- Ensure all connections are secure and insulated to prevent short circuits and corrosion.
- Verify the alarm operates correctly by engaging reverse gear.
4. Operation
The ECCO SA917N Back Up Alarm is designed for automatic operation. Once properly installed and wired to the vehicle's reverse light circuit, it will activate whenever the vehicle is shifted into reverse gear.
4.1 Smart Alarm Functionality
This model features a 'Smart Alarm' capability. This means the alarm's sound output is dynamic:
- In quiet environments, the alarm will operate at a lower sound level, typically around 87dB(A).
- As the ambient noise level around the vehicle increases (e.g., in busy traffic or construction sites), the alarm will automatically increase its sound output, up to a maximum of 112dB(A), to ensure it remains audible and effective.
This intelligent adjustment helps prevent unnecessary noise pollution while guaranteeing safety warnings are heard when needed most.
5. Maintenance
The ECCO SA917N Back Up Alarm is built for durability and requires minimal maintenance. Regular inspection can help ensure its continued reliable operation.
- Cleaning: Periodically clean the exterior of the alarm with a damp cloth to remove dirt and debris. Avoid using harsh chemicals or abrasive cleaners.
- Inspection: Regularly check the mounting hardware for tightness and ensure the alarm is still securely attached. Inspect the wiring for any signs of wear, fraying, or corrosion.
- Functionality Test: Periodically test the alarm by engaging reverse gear to ensure it activates and produces sound.
6. Troubleshooting
If your ECCO SA917N Back Up Alarm is not functioning as expected, consider the following common issues and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Alarm does not sound when in reverse. | No power to the alarm; loose or corroded wiring; faulty reverse light switch; alarm malfunction. | Check all wiring connections for security and continuity. Verify power is present at the alarm's red wire when in reverse. Inspect vehicle's reverse light switch. If all else fails, the alarm may need replacement. |
| Alarm is too quiet or not loud enough. | Ambient noise level is low (Smart Alarm feature); obstruction blocking sound; incorrect mounting. | Understand that the 'Smart Alarm' adjusts volume based on surroundings. Test in a noisy environment to see if volume increases. Ensure no physical obstructions are blocking the speaker. Verify correct mounting direction. |
| Alarm sounds continuously. | Incorrect wiring; short circuit in reverse light circuit. | Re-check wiring to ensure the alarm is only receiving power when reverse gear is engaged. Inspect the vehicle's reverse light circuit for any short circuits. |
