kenwood NX-230EXE / 330EXE

The ATEX/IECEx certified NEXEDGE® NX-230EX and NX-330EX hand portable radios bring all the benefits of NEXEDGE® digital performance and flexibility to new markets.

The introduction of NEXEDGE® digital ATEX means that you can now offer a Kenwood digital solution to customers operating ATEX/IECEx certified equipment – secure in the knowledge that it has been built on the proven performance and reliability of NEXEDGE® with over 700,000 devices in use.

Presented in an easily recognisable colour (this distinguishes it from our analogue ATEX and non ATEX certified radios), NEXEDGE® ATEX joins our existing and highly successful analogue ATEX radios to meet the growing demand from customers operating in hazardous and explosive environments who require equipment that is safe, dependable and delivers exceptional range and performance. Safety, security, flexibility and high performance – the hallmarks of NEXEDGE® ATEX.

NEXEDGE® ATEX hand-portable models:

NX-230EX (136-174MHz) VHF Digital and FM Hand-Portable Transceiver
NX-330EX (400-470MHz) UHF Digital and FM Hand-Portable Transceiver

NEXEDGE® ATEX hand portables are certified to European Union Directive 94/9/EC, commonly called the ATEX Directive, and IECEx International Scheme:

ATEX Directive 94/9/EC
II 2G Ex ib IIC T4 Gb – Gas protection
II 2D Ex ib IIIC T110°C Db – Dust protection
I M2 Ex ib I Mb – Mining protection

IECEx Scheme

Stable Communications in a Noisy Environment

Digital voice technology offers superior voice quality with the NX-230EX/330EX without the background noise, even in very noisy environments such as a drilling platform or an oil refinery.

In addition to the noise cancelling technology, Kenwood worked with 3rd party suppliers to offer heavy duty audio accessories for the NX-230EX/330EX. The combination of Kenwood digital noise cancellation technology and ATEX certified accessories will provide optimum clarity to voice communication in noisy environments.

Extended Communication Range

The NX-230EX/330EX strikes a successful balance between a high protection class, excellent performance and 1.2W of effective radio output power.

As RF signal strength weakens with distance, FM analogue reception becomes increasingly noisy and intermittent. In contrast, NXDN Digital improves communication distance with higher reception performance, driven by the better sensitivity of a true 6.25kHz very narrow band solution and low bit error rate.

Easy and Controlled Migration to Digital

Mixed Mode: FM analogue and NXDN digital conventional operation can share the same RF channel. Subscriber units and Base stations autosense incoming FM analogue or NXDN digital calls and talkback or repeat the same mode.

Variety of Signalling: 5-tone Signalling with built-in 5-tone encoder/decoder provides 6-different formats, ZVEI, ZVEI2, CCIR, EIA, EEA and the Kenwood format. It is also possible to set not only 5-tone but up to 8-tone signalling, 2-frames 5-tone and the 3-frames 5-tone signalling.

Supports MPT1327 trunked operation: The NX-230EX/330EX supports MPT1327 trunking operation. From small groups to large scale fleets, the radios offer reliable communications over existing MPT trunking networks. This flexibility provides a simple and straight-forward migration path from an analogue system to a digital system with equipment investment made in a phased and controlled manner.

QT/DQT/DTMF: The Encoder/Decoder function uses QT/DQT to segregate talk groups, so users only hear calls from their own group. DTMF PTT ID is included for dispatch operations or for a simple remote control application. The DTMF decode capabilities include a selective call ID, transpond with ID, ‘wild card’ group calling and radio stun.

FleetSync® PTT ID, SelCall & Emergency: Employing Kenwood’s FleetSync® digital signalling protocol, the NX-230EX/330EX have PTT ID (ANI: Automatic Number Identification) and Selective Calling capabilities for managed dispatch operations. For hazardous/dangerous environments, a PF key can also be programmed for easy accesses to Emergency status functions to alert the dispatcher and/or operator to a user in distress.

Ready for Emergency Scenarios

These functions provide security and safety for users who work remotely as well as for those working in hazardous areas. If the radio user gets into a situation which classifies as an emergency, the transceiver automatically sends a help signal to a pre-determined person or system.

Standard Man-down: Standard Man-down function is available as a factory setting. If the radio position changes to horizontal (or slanted) for a pre-set period, an alert signal is transmitted.

Advanced Motion Detection (Software License Option – Requires activation file):

  • Stationary mode: When the radio user carrying the radio does not move for a pre-set period, an alert signal is transmitted.
  • Motion mode (Panic): When the radio user carrying the radio moves a lot (in a running motion for example) for a certain period, an alert signal is transmitted.

Lone Worker Function: This advanced feature provides an extra layer of security and safety for individuals. As long as the radio is used regularly, the radio operates normally; however, if there is a long pause with no user interaction, the radio will sound an alert. In the absence of further response from the user, the NX-230EX/330EX will place an emergency call to a pre-determined person or group of people.

The Lone Worker Function can be used in combination with other Emergency functions.

Emergency Key (Orange Key) A clearly identified orange key can be used exclusively for emergency signalling to send a help signal to a pre-determined person or group of people.

Built-In GPS receiver* for Personnel Location Management

A built in GPS receiver is capable of locating personnel for safety and resource management at a communication site. The NX-230EX/330EX has the capability to send GPS data with voice simultaneously. The data communication would not disturb voice communication.

Over-the-Air-Alias (OTAA)

Caller Group or Unit name can be displayed automatically on the called unit’s LCD display when a call is made. The user name and ID is sent with voice data simultaneously. This feature is invaluable for radio fleets where user (or radio names) are changing on a regular basis. Combined with Over-the-Air-Programming (OTAP) this allows easier user management and control, saving costs and increases efficiencies.

Telephone Interconnect

Phone calls to the system or outgoing calls to PSTN or PABX will pass through the Telephone Interface KTI-4. Adding a telephone interconnect solution to a NEXEDGE® trunked system will require a KTI-4 with an external telephone patch. A VOIP based solution is available.

IP65 / IP67 Protection

The NX-230EX/330EX radios are compliant with stringent IP65 and IP67 environmental standards. Radios with this certification are designed to provide uncompromising performance in heavy rain or excessively dusty conditions.
