Dakota Alert DCHT-4000 Wireless Driveway Alarm Transmitter Instruction Manual

Introduction

The Dakota Alert DCHT-4000 is a wireless driveway alarm transmitter designed to detect incoming vehicles. It utilizes a 25-foot rubber hose vehicle sensor to send a wireless signal to a compatible Dakota Alert 4000 Series receiver (sold separately) whenever a vehicle drives over the hose. This system offers a wireless range of up to one mile, providing reliable monitoring for your property.

Setup

Setting up your DCHT-4000 transmitter is designed for ease of installation. Follow these steps for proper deployment:

1. Battery Installation: The DCHT-4000 operates on one 9-volt battery (not included). Open the transmitter unit and insert the 9-volt battery, ensuring correct polarity. The battery is expected to last a year or more under residential use.
2. Sensor Placement: Lay the 25-foot rubber hose across your driveway or desired detection area. Ensure the hose is positioned where vehicles will drive over it. The hose connects to the transmitter unit.
3. Transmitter Placement: Position the transmitter unit in a secure, weather-protected location near the hose, ensuring it has a clear line of sight or minimal obstructions to the intended receiver for optimal wireless range.
4. Pairing with Receiver: The DCHT-4000 uses simple code-learning technology for pairing. Refer to your Dakota Alert 4000 Series receiver's manual for specific pairing instructions. Up to 16 sensors can be paired with one receiver, or an unlimited number of receivers can be paired to one sensor.

Operating Instructions

Once the DCHT-4000 transmitter is set up and paired with a compatible receiver, its operation is automatic:

• Vehicle Detection: When a vehicle drives over the rubber hose sensor, the pressure change within the hose activates the transmitter.
• Signal Transmission: The transmitter sends a wireless signal to the paired Dakota Alert 4000 Series receiver. This signal can travel up to one mile in optimal conditions.
• Receiver Alert: The receiver will then produce an audible alert or visual indication, notifying you of an incoming vehicle.

Maintenance

To ensure continued reliable performance of your DCHT-4000 system, periodic maintenance is recommended:

• Battery Replacement: The 9-volt battery in the transmitter should be replaced annually or when the receiver indicates a low battery signal. Timely replacement prevents signal loss.
• Hose Inspection: Regularly inspect the rubber hose for signs of wear, cracks, or damage, especially in high-traffic areas or harsh weather conditions. While durable, the hose may wear out over time and require replacement to maintain detection accuracy.
• Transmitter Unit Cleaning: Keep the transmitter unit clean and free from dirt, debris, or insect nests that could obstruct its operation or signal transmission.

Troubleshooting

If you encounter issues with your DCHT-4000 system, consider the following troubleshooting steps:

• No Signal/Intermittent Signal:
  • Check the 9-volt battery in the transmitter. Replace it if it's old or depleted.
  • Inspect the rubber hose for damage or kinks that might prevent proper pressure detection.
  • Ensure the transmitter and receiver are within effective wireless range and that there are no new obstructions (e.g., large metal objects, dense foliage) between them.
  • Verify that the transmitter is correctly paired with the receiver. Refer to your receiver's manual for re-pairing instructions.
• False Alarms:
  • Ensure the hose is laid flat and securely, preventing movement from wind or small animals that could trigger it.
  • Check for any debris on or around the hose that might be causing false triggers.
• Shortened Wireless Range:
  • Replace the transmitter battery.
  • Relocate the transmitter or receiver to improve line of sight.
  • Consider environmental factors like dense trees, hills, or large metal structures that can reduce wireless range.
