Wired Doorbell Atlo ATLO-DB-1 — Mechanical Chime, Single Door, Low-Voltage

The Wired Doorbell Atlo ATLO-DB-1 is a mechanical chime designed for single-door wired installations. It operates on low-voltage power and connects through a standard two-wire circuit to compatible push buttons and a doorbell transformer. The chime delivers a clear acoustic signal when the button is pressed and is intended for residential homes or small commercial entrances where a reliable, low-maintenance visitor alert is required.

Advantages

The mechanical construction provides a distinct, audible chime without the need for electronic tone generation, reducing complexity and potential electronic failures. Its two-wire connection simplifies installation with common doorbell wiring and standard transformers. The unit requires minimal maintenance due to its straightforward mechanical design and provides consistent operation in typical indoor environments.

• Single-door residential entrances
• Small office or retail entryways
• Secondary doors such as back or side entrances
• Replacement of existing wired mechanical door chimes

How to use

Turn off power to the doorbell circuit at the transformer or breaker before beginning installation. Mount the chime housing in the chosen indoor location and connect the two conductor wires from the push button and transformer according to the manufacturer’s wiring diagram.
