The industrial grade VX-450 Series maximises worker uptime with expanded safety applications and convenient built-in features designed for heavy duty use.
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 mode is a built-in timer that requires the user to reset at a redetermined 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 II (ARTS II) is included to inform the user that other ARTS II – equipped radios are within communication range.
No two job sites are alike and 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.
The VX-450 Series withstands job site abuse meeting military standards for ruggedness and meets the IP57 ingress protection standard where water does not harm the radio when submersed to a depth of 1 metre for up to 30 minutes.
Features 700 mW loud audio output ideal for noisy work environments. Includes Multi-lingual Channel Announcement which loudly speaks the channel description to simplify changing channels. Alternatively record your own announcements to allow easier navigation.
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 and store up to 120 seconds of voice messages using the optional DVS-8 Voice Storage unit.
Includes MDC-1200 encode/decode along with DTMF, 2-tone and 5-tone encode/decode providing selective radio calling and efficiency in supporting a variety of discrete communications needs.
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 site or plant operation. The VX-459 also includes Direct Channel Entry to punch in the channel desired from the keypad for fast navigation.
