Introduction
This manual provides detailed instructions for the installation, operation, and maintenance of your Safeguard Supply ERA-DOORBELL EXTENDER Wireless Doorbell Kit. This system is designed to convert your existing hard-wired doorbell into a wireless system, allowing you to hear your doorbell in various locations throughout your home or property.
Product Overview
The Safeguard Supply ERA-DOORBELL EXTENDER system consists of two main components: a transmitter and a plug-in receiver (chime unit).
- Transmitter: This small unit connects to your existing wired doorbell chime. When your wired doorbell is pressed, the transmitter sends a wireless signal to the receiver.
- Plug-in Receiver (Chime Unit): This unit plugs into a standard AC outlet and produces an audible chime and/or visual strobe light when it receives a signal from the transmitter. It offers a wireless range of up to 4000 feet (approximately 3/4 mile).

This system is designed for use with traditional wired doorbells and is not compatible with video doorbells.
Setup and Installation
Follow these steps to install your Safeguard Supply ERA-DOORBELL EXTENDER:
- Transmitter Installation:
- Locate your existing wired doorbell chime unit.
- Important: Turn off the power to your doorbell circuit at the breaker box before proceeding.
- Open your existing doorbell chime unit. You will typically find three terminals: FRONT, REAR, and TRANS (Transformer).
- Connect the wires from the ERA-DOORBELL EXTENDER transmitter to the corresponding terminals on your existing doorbell chime.
- Connect the Red Wire to the FRONT terminal.
- Connect the Black Wire to the TRANS (Transformer) terminal.
- Connect the White Wire to the REAR terminal (if applicable, otherwise leave unconnected if you only have a front doorbell).

- Re-apply power to your doorbell circuit.
- Receiver (Chime Unit) Placement:
- Plug the receiver unit into any standard AC electrical outlet within the desired listening area. The system offers a wireless range of up to 4000 feet.
- Ensure the receiver is not obstructed by large metal objects or thick walls, which can reduce wireless range.

Troubleshooting
