Dakota Alert DCHT-2500 Wireless Rubber Hose Transmitter

Warnings

This device complies with Part 15 of the FCC rules, Operation of this device is subject to the following conditions: 1. This device may not cause harmful interference. 2. This device must accept any interference, including interference that may cause undesired operation.

Installation:

The DCHT-2500 transmitter consists of a transmitter box and 25 feet of hose. To install, connect the hose to the stem on the transmitter box, then lay the hose across the driveway. Mount the transmitter box on a tree or wooden post at least three feet off the ground (see figure 1). Avoid using steel posts as this may interfere with the radio signal. The maximum range of the system is about 2500 feet, however, obstructions such as hills, trees and metal siding can reduce the range.
Connect a 9-volt alkaline battery to the transmitter. The battery should last about 6 to 12 months under normal conditions. Once the battery is connected, the system will need a few seconds to warm up. After this time the transmitter will detect vehicles driving over the hose. Make sure that there are no kinks in the hose, as this may keep the transmitter from detecting.
When the transmitter detects a car, it will send a signal to the receiver, which will sound one of four different tones (Classical, Westminster Chime, Ding Dong, or Whistle) for a few seconds.

Operation: (Always test unit prior to installation) The control box is powered by one 9-volt battery.

Coding the transmitter:

Note: The transmitters and receivers are preset at the factory. DO NOT change settings, unless changing the tune or experiencing false signals.

1.  Open the transmitter box. The first thing you will see is the air switch (Figure 2). Directly below the air switch is the transmitter’s radio (Figure 3).
2.  Locate the dip switches on the radio (2)(3).
3.  Switches 1-8 are for the frequency setting (256 combinations). If needed, set switches 1-8 (2) to match the eight switches in the receiver.
4.  Switches 9 and 10 (3) are for the channel setting on the transmitter. Use these to set the tone you prefer. The four channels are listed in the table on page 5.

Table to select tones:

Coding the receiver:

1.  Open the receiver case by inserting a small screwdriver into one of the pry notches on the side of the case. (refer to receiver manual)
2.  Gently lift off the front cover.
3. Locate the eight dip switches on the receiver and make sure they are set identically to dip switches 1-8 on the transmitter.

Note: If more than one transmitter is used with the receiver, the first eight dip switches of all transmitters must match the eight dip switches of the receiver.
Note: Whenever a change is made to any jumper or the dip switches, the receiver must be turned OFF and then back ON to operate properly.

• Frequency: 433.92 MHz
• Operating range: -30˚F to 120˚F
• Battery life: 6-12 months

LOW BATTERY ALERT: If the receiver sounds a second alert 30 seconds after the first alert, provided nothing trips the transmitter again, the 9-volt battery in the transmitter should be changed.

Troubleshooting the DCHT-2500
If the transmitter is not detecting, try one of these:

• Change the battery in the transmitter.
• Make sure the transmitter and receiver are coded alike.
• Move the transmitter closer to the receiver.
• Keep the transmitter away from large metal objects that may interfere with the radio signal.
• Adjust the screw on the air switch in the transmitter (Figure 2) (1) by turning it clockwise. This will increase the sensitivity.
• If the contacts are touching, the system will not work.

If the transmitter is giving false signals, try one of these:

• Adjust the screw on the air switch in the transmitter (Figure 2) (1) by turning it counterclockwise. This will decrease sensitivity.
• Set the transmitter and receiver to a different code setting. Refer to instructions on pages 3 and 5.
