Durable on-the-job responsiveness

The industrial grade VX-450 Series maximises worker uptime with expanded safety applications and convenient built-in features designed for heavy duty use.

Monitor Worker Safety

The VX-450 series, as with all the Vertex Standard radios, has four key features to ensure the safety of the user.
  • Emergency Alert
    The user signals out an emergency notification with just a press of a button on the radio, which will then be switched to a designated channel to send an alert for help.
  • Lone Worker Alert
    A built-in timer that requires the user to reset at a predetermined interval. If not reset, the radio automatically switches to emergency mode to alert help.
  • Vertex Standard’s exclusive Auto-Range Transpond System (ARTS™)
    A function that keeps the user within communication range with other ARTS™- equipped radios, so constant contact is always known.
  • Man Down Function (with DVS unit)
    Programmed to monitor a variety of worker timed safety scenarios vertically and horizontally as well as worker degree of motion. Adjusting the settings of the 3-axis sensor adapts the radio to each distinct work environment to monitor movement.

Resistance for Extreme Environments

The VX-450 Series water-resistant radios are built to submerse up to 30 minutes at a depth of 1 meter and it has been tested to meet military standards for ruggedness and the IP67 ingress protection standard.

Audio and Voice Detection Sensitivity Audio

Equipped with 700 mW audio output that’s perfect for noisy work environments. Users can make us of the Channel Announcement function, which loudly speaks the channel description to simplify changing channels when focused on other tasks simultaneously.

Voice

Equipped with Voice Activation (VOX) function and when used with the MH-81A4B headset, users are able to transmit voice without pressing the Push To Talk button for hands-free operations. Record and store up to 120 seconds of voice messages using the optional DVS-8 Voice Storage unit.

Manageable System for Large Group Communications

Both the VX-459 and VX-454 radios have a massive 512-channel capacity and 32 groups to easily manage a variety of calls at the most complex job sites or plant operations. The VX-459 also includes Direct Channel Entry to punch in the channel desired from the keypad for fast navigation.
