Image: This image illustrates the three simple steps for initial setup: 1. Plug the receiver into an outlet. 2. Remove the battery insulating tab from the sensor. 3. Install the sensor on a door or window.

4.1 Receiver Installation

1. Plug the receiver into a standard AC power outlet (100-240V) in your desired location.

4.2 Sensor Installation

Before mounting, remove the battery insulating tab from the sensor. Ensure the sensor and magnetic strip are aligned and the gap between them is no more than 0.4 inches (1 cm) when the door/window is closed.

Image: This diagram visually demonstrates the critical installation gap between the sensor and its magnetic strip, emphasizing that it must be less than or equal to 0.4 inches for proper function.

Mounting Options:

• Adhesive Tape Mounting:
  

  Image: This image shows a three-step process for installing the sensor using adhesive patches: 1. Apply adhesive to the back of the sensor. 2. Peel off the protective film. 3. Press the sensor firmly onto the desired surface.

  1. Clean the surface where the sensor will be mounted.
  2. Apply the double-sided adhesive tape to the back of the sensor and the magnetic strip.
  3. Firmly press the sensor and magnetic strip onto the door/window frame, ensuring they are aligned and within the 0.4-inch gap when closed.
• Screw Mounting:
  

  Image: This image illustrates the three steps for screw mounting the sensor: 1. Position the sensor and mark screw holes. 2. Secure the sensor with screws. 3. Attach the magnetic strip next to the sensor.
  1. Use the provided screws and screw locks to secure the sensor and magnetic strip to the door/window frame.
  2. Ensure the sensor and magnetic strip are aligned and within the 0.4-inch gap when closed.

4.3 Pairing Additional Sensors/Receivers (If Needed)

If you purchase additional sensors or receivers, or if a device loses its pairing, follow these steps:

1. Plug in the receiver.
2. Press and hold the 'Setting' button on the receiver for 3-5 seconds until the LED indicator flashes rapidly. This indicates pairing mode.
3. Within 10 seconds, separate the sensor and magnetic strip (or press the sensor's test button if available). The receiver will chime to confirm successful pairing.
4. Repeat for each additional sensor or receiver.

5. Operation

6. Expandability

The STECHRO Wireless Door Chime system is highly expandable:

• Each receiver can be paired with up to 20 chime sensors.
• Each door sensor can be paired with up to 20 receivers.
• You can assign different ringtones to each sensor, allowing you to identify which door or window has been triggered.

7. Maintenance

7.1 Sensor Battery Replacement

The door sensors are powered by 3 x 12V batteries (included). When the sensor's LED indicator no longer flashes or the signal becomes weak, it's time to replace the batteries.

Image: This image displays a sensor mounted on a door, accompanied by a red battery icon, clearly indicating a low battery status that requires attention.

1. Carefully open the sensor casing.
2. Remove the old batteries and insert new 12V batteries, ensuring correct polarity.
3. Close the sensor casing securely.

The batteries are designed for long-lasting performance, offering over 15,000 usage times.

Image: This graphic depicts a fully charged battery, signifying the impressive battery life of over 15,000 usage times for the sensors.

8. Troubleshooting

• No Chime Sound:
  • Ensure the receiver is properly plugged into a working power outlet.
  • Check if the volume is set to an audible level (not mute mode).
  • Verify the sensor battery is not depleted. Replace if necessary.
  • Re-pair the sensor and receiver if they have lost connection (refer to Section 4.3).
• Weak or Intermittent Signal:
  • Ensure the distance between the sensor and receiver is within the 600ft range in an open area. Walls and obstacles can reduce this range.
  • Check for strong electromagnetic interference from other devices.
  • Verify the sensor battery is not low.
• Sensor Not Triggering:
  • Ensure the sensor and magnetic strip are correctly aligned and the gap is no more than 0.4 inches when the door/window is closed.
  • Check the sensor battery.
  • Re-pair the sensor with the receiver.
