Setup and Programming
Follow these steps to set up and program your Safeguard Supply EX1000S Doorbell Extender:
- Install Battery in Transmitter: Open the transmitter casing and insert the provided CR123A 3.0V Lithium Battery. Ensure correct polarity.
- Plug in Receiver: Plug the wireless receiver into a standard electrical outlet in your desired location.
- Enter Programming Mode: On the receiver, press and hold the program button (often indicated by a small dot or square icon) until the LED indicator lights up.
- Select Melody: While in programming mode, press the melody button (often indicated by a music note icon) repeatedly until you hear the desired chime sound.
- Pair Transmitter (Front Door): On the transmitter, press the "Front Door (Red Wire)" button. The receiver should emit the selected melody, confirming successful pairing for the front door.
- Pair Transmitter (Back Door - Optional): If you have a back door chime, press the "Back Door (White Wire)" button on the transmitter. The receiver should emit a different melody (or the same if only one is programmed), confirming successful pairing for the back door.
- Exit Programming Mode: Press the program button on the receiver again to exit programming mode. The LED indicator should turn off.
- Test Connection: Briefly touch the red wire from the transmitter to the common wire (usually black) on your existing wired doorbell chime. The receiver should sound the programmed melody. Repeat for the white wire if a back door is connected.
Wiring Instructions for Transmitter
The transmitter connects to your existing wired doorbell chime. It is crucial to identify the correct wires from your chime:
- Red Wire: Connect to the terminal on your existing doorbell chime that corresponds to the Front Door.
- White Wire: Connect to the terminal on your existing doorbell chime that corresponds to the Back Door (if applicable). If you do not have a back door, this wire can remain unconnected.
- Black Wire: Connect to the Transformer terminal (common wire) on your existing doorbell chime.
Note: Some wired doorbell systems may vary. Consult your existing doorbell's manual if you are unsure about the wiring.
