Aggregated specification data lists this device as a closed-loop notification system operating on the 433.92MHz radio frequency. This analog transmission protocol allows for superior signal penetration through structural materials like drywall and wood compared to higher-frequency 2.4GHz standards. The transmitter requires a 12V 23A alkaline battery to maintain peak signal output, while the receiver utilizes a standard linear power supply transformation to drive a 0.5W internal speaker. Ingress protection metrics confirm a rating of IP55, indicating the chassis is shielded against driving rain and solid particulates.
Performance metrics demonstrate a 1000ft line-of-sight range, though structural density will attenuate this distance in residential applications. Standardized testing protocols show a chime response latency of approximately 20ms, providing near-instantaneous audio output upon trigger. Because the system lacks a network interface, all data remains local, eliminating dependencies on external cloud servers or internet bandwidth. The receiver module provides an adjustable audio range from 0dB to 110dB, utilizing a sound library of 36 distinct melodies stored on a local chip.
Operational highlights for this unit include:
- Trigger Mechanism: Push-button RF transmitter
- Receiver Power: 110V AC plug-in
- Notification Type: Acoustic only
If your security requirements necessitate a digital record of visitor interactions, transitioning to a wireless video doorbell system provides the necessary visual logging this audio-only unit lacks. This hardware sits within the professional classification of doorbell bundles with chimes used for localized perimeter alerting.
