The industrial grade DTEx Fire Fighter Series is designed and approved to meet the latest MED standard implementation regulation MED/5.20 and European ATEX directive.

The ultra durable fire-red coloured DTEx Series sets the benchmark for next-generation MED compliant Firefighter radios. Standard features include both analogue and digital modes of operation, high visibility OLED display, high torque ergonomic controls designed for gloved-hand use, and industry-leading IP68 2m 4 hours submersible rating, to provide 100% reliability and usability even in the most extreme conditions.



Channels – The DT885FF Marine can be programmed with both analogue and digital channels, this is clearly indicated on the display together with the frequency. If a semi duplex channel is programmed the word “Repeater” will be displayed instead of the frequency.

Benefits of digital – Digital mode which gives significantly better audio, extended range and longer battery life in comparison to analogue radios.

Environmental protection to IP68 (2 Meters for 4 hours) – The DT885FF offers the highest submersibility rating of any manufacturer. This protects against corrosion, withstanding total immersion in water to a depth of 2 meters for 4 hours to protect against the likely hazards encountered in extremely wet environments.

Robust accessory socket – DT885FF accessory socket has been specifically designed so that when an accessory is secured to the portable, the connection can withstand any amount of punishment; from dropping to careless misuse. The rugged, multi-pin interface and Micro-USB socket are both submersible and gold-plated to minimize any risk of damage and protect against corrosion. To ensure the integrity of IS protection levels any accessory connected to the handset automatically undergoes a validation process to safeguard against non-compliant accessories being used. All DT885FF accessories incorporate a robust locking connector to further safeguard the safety of the user.

High contrast white on black OLED display – the DT885FF model benefits from a high contrast white on black OLED display that delivers superior readability in varying light conditions adding to the DT885FF’s intuitive user interface.

Li-Ion battery technology & improved talk time – DT885FF radios are supplied with the latest intelligent Lithium-Ion battery technology as standard. One key advantage of Lithium-Ion battery technology is the way it eliminates ‘memory effect’, meaning that there is no need to fully discharge your battery before recharging. As a result of this, you are assured of a full charge each and every time you take your Entel battery from its charger.

Superior Audio – DT885FF portables deliver loud & crisp audio no matter what environment you are in. All of the DT885FF’s range of accessories incorporate a robust locking plug and high-grade cable and benefit from Entel’s proprietary “Smart Speech Tailoring” technology. This automatically detects the type of accessory connected and optimizes the audio accordingly to deliver the very best performance.


Simple onboard reprogramming app – With our free, unique and simple to use PC app, you can easily re-program a DT885FF radio whilst still onboard. The user friendly app makes it easy to drag and drop a new programming file from an email to your DT885FF radio(s).

This is a simple and seamless process that can be carried out by non-technical personnel.

Keylock – To avoid accidental operation, your radio’s keys & controls can be locked.

Programmable channel monitor button – If you have channel protection enabled on your DT885FF portable, all signals other than your own networks will be filtered out. This can be temporarily disabled allowing you to monitor all signals on your channel.

Audio Accessories & BA Support – Entel also offer an extensive range of accessories including Draegor BA, most popular for Fire Fighters is the CXR bone conductive throat and skull microphones which eliminate ambient noise, further enhanced by DT885FF’s speech tailoring technology delivering intelligible communications first time, every time

Scan – a programmable button allows channel scanning.


ATEX IIB T4 Approved – The DT885FF ATEX certified portables meet IIB T4 – the most stringent ATEX ratings as per EU directive 94/9/EC.
