Aggregated data for the Tecknet Door and Window Alarm indicates a strictly analog architecture without an integrated logic chipset or wireless radio. Performance metrics confirm a peak acoustic output of 120dB from a piezo siren, triggered by the interruption of a magnetic reed circuit. Technical specifications show the device is powered by three LR44 alkaline cells, which are subject to voltage sag over time.
Material analysis reveals a mechanical slide-switch for mode selection and an adhesive-based mounting system. Standardized testing identifies a magnetic gap tolerance of 10mm; exceeding this distance may prevent the siren from triggering. This unit does not provide remote notifications, digital event logs, or integration with home automation hubs.
- Modes of operation: On, Off, Chime.
- Power Source: 3x LR44 Button Cells.
Forensic data suggest that battery contact oxidation and mechanical fatigue of the slide-switch are the primary failure modes. The device is intended for localized audible alerts and provides no perimeter monitoring capabilities beyond the physical hearing range of the siren.
The TECKNET 3-Pack Door and Window Alarms is a basic localized alternative for those not requiring smartphone integration or remote monitoring.
This device is classified under wireless sirens and panic buttons as a standalone audible alert tool.
