Technical specifications for the Vilfet 4-in-1 detector classify it as an analog-digital hybrid device for the monitoring of combustible gases and carbon monoxide. The unit utilizes a catalytic combustion sensor for explosive gas detection (Methane, Propane, Natural Gas) and an electrochemical sensor for CO. A real-time visual display provides parts-per-million (PPM) data for environmental assessment.
The hardware architecture features an AC plug-in design with a 9V battery backup. Upon activation, a mandatory 180-second warm-up period is required for sensor stabilization. The integrated piezo-electric buzzer provides an 85dB local siren. This device operates as a standalone unit without native Wi-Fi or Zigbee connectivity, prioritizing local audible alerting over remote notifications.
Key operational specifications include:
- Thresholds: Monitors for Lower Explosive Limit (LEL) and CO concentrations.
- Siren: 85dB high-decibel output.
- Display: Digital PPM visualizer.
Performance data suggests a 3 to 5-year operational lifespan for the sensing elements. Due to the lack of smart self-testing protocols, manual testing is required monthly to ensure mechanical buzzer functionality. The plug-in chassis design may occupy significant space on a standard duplex wall outlet.
Users seeking a local fail-safe for fuel-burning appliances may deploy the Vilfet 4-in-1 Detector in kitchens or mechanical rooms. This hardware belongs to the safety and smoke alarm classification of protective devices.
