Performance metrics indicate this system utilizes a high-output piezo buzzer capable of 115dB acoustic pressure, exceeding standard residential alert volumes. The transmission architecture is based on a 433.92MHz oscillator circuit, which provides a near-instantaneous trigger response. The transmitter is powered by a CR2032 lithium battery cell, while the receivers utilize standard AC plug-in power. Material specifications for the transmitter housing confirm an IP55 rating, though maintenance protocols suggest verifying the silicone gasket alignment during battery changes to prevent moisture-induced phantom ringing.
Structural analysis reveals the receiver retains volume and chime settings via an internal memory function during power interruptions. While the system claims a 1,000-foot range, technical audits show significant signal attenuation when passing through masonry or environments with high RF floor noise. The sound library is stored on a local CMOS chip containing 66 distinct melodies. Because this is an analog-based RF system, it does not support remote logging, smartphone notifications, or two-way audio communication, functioning strictly as a unidirectional acoustic alert system.
Operational highlights for this unit include:
- Acoustic Output: 115dB peak
- Power Source: CR2032 (Transmitter) / AC Plug-in (Receiver)
- Interface: Push-button trigger
If you require the ability to monitor visitor activity from a mobile device, the Letswill 115dB Doorbell should be supplemented with a camera-enabled system. This unit represents a high-decibel variant within the broader doorbell bundles with chimes hardware class.
