The Dinsafer Helio DVBH1 is a wireless vibration sensor designed as an accessory for the Helio smart alarm system. When the sensor detects vibration, it immediately transmits a trigger signal to the Helio main panel, which can then activate the siren and send alerts.

The sensor is powered by a single CR123A (3 V) button battery and features RF supervision to confirm the radio link with the panel is active. Tamper protection triggers an alert if the unit is removed. Low battery warnings are sent by the main panel via SMS when replacement is needed.

Key Features

• Vibration detection with immediate trigger signal to the main panel
• RF supervision for continuous link monitoring
• Tamper protection
• Low battery SMS alert from the main panel
• Wireless transmission at 433.92 MHz, up to 1000 m without obstacle
• Powered by 1 × CR123A (3 V) battery

Product Benefits

• Vibration sensing is effective on safes, drawers, doors, and windows — any surface that shakes on unauthorised contact
• RF supervision provides a continuous health-check of the wireless link, flagging connection loss before it becomes a security gap
• Tamper protection means physically removing the sensor is itself an alarm event
• At only 18 g without the battery and 84×26×22 mm, the sensor attaches to surfaces without being conspicuous
• SMS battery replacement notification from the panel eliminates manual battery inspection

Why You'll Love It

• One sensor covers a wide range of attachment points — safes, filing cabinets, window frames, and door panels all work with a single sensor type
• The slender 84×26×22 mm form factor fits on the edge of a drawer or safe door without interfering with normal operation
• CR123A batteries are widely available and the ≤15 μA standby current gives long service between changes
• Part of the Helio ecosystem: pairs directly with the same panel as door sensors, smoke detectors, and sirens
