Monitor Worker Safety

As with all Vertex Standard radios, the VX-450 series includes built-in Emergency and Lone Worker alerts. Emergency notification is user-initiated with a press of a button for the radio to switch to a designated channel and send an alert for help. Lone Worker is 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.

When constant contact is required at all times, Vertex Standard's exclusive Auto-Range Transpond System (ARTS™) is included to inform the user that other ARTS™-equipped radios are within communication range.

The optional Man Down function (with DVS-9 unit) is programmable 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.

Intrinsically Safe Option for Hazardous Locations

Instrinsically safe models are SGS certified to the requirements of ANSI/UL913 5th Edition for use in Class I, II, III, Division I; Groups C,D,E,F,G; Temp T3C hazardous locations.

Solid Build for Extreme Environments

Withstands job site abuse meeting military standards for ruggedness and meets the IP 57 ingress protection standard where water does not harm the radio when submersed to a depth of 3 feet for up to 30 minutes.

Loud Audio and Voice Responsiveness

Features 700mW loud audio output ideal for noisy work environments. Includes Channel Announcement which speaks the channel description to simplify changing channels when focused on other tasks simultaneously. Features voice activation (VOX) when used with MH-81A4B headset that enables users to transmit voice without pressing the Push To Talk button for hands-free operation. Record up to 120 seconds of voice messages using the optional DVS-8 Voice Storage unit.

Built-in Selective Signaling Modes for Greater Flexibility

Includes MDC-1200® encode/decode along with both 2-tone and 5-tone encode/decode providing selective radio calling and efficiency in supporting a variety of discreet communications needs.

Manageable System for Large Group Communications

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