DEF fire detector range
Reliable fire detection to protect your buildings and your business
Fire detection is the first link in your safety chain. It identifies a fire quickly and triggers the action needed to protect people, property and operations.
Offices, healthcare facilities, schools, hotels, industrial sites, museums or public-access buildings: DEF detectors are built for the most demanding environments.
Designed to fit into a complete fire safety chain, the LOTA range meets the reliability, compliance and continuity requirements expected of your fire safety installations.

WE WATCH OVER, YOU LIVE
Fire detectors are with you all your life. Usually without you noticing.
In hotels, schools, offices, hospitals, cultural venues and industrial buildings, fire detectors are on watch at all times.
Why the choice of detector matters
The wrong detector can weaken your whole fire safety chain
Humidity, dust, water vapour, nuisance smoke, great height or architectural constraints: every building sets its own limits. The right detector is not simply one that detects, but one that detects correctly in your real operating environment.

Mismatch between the detector chosen and the real fire scenario
The Lota range
A range designed for every environment
Every building has its own constraints. DEF helps you choose the right detector for your use, your environment and your requirements.
Strengths of the range
Why choose the DEF LOTA range?
A new generation of fire detectors designed to strengthen the reliability of your installations, adapt to your constraints on site and keep your buildings safe over time.
Fiabilité
Stable, certified detection that identifies fires quickly while limiting unwanted alarms.
Leading-edge technology
Multi-sensor detectors that analyse several signals to detect fires earlier and more accurately.
Complete adaptability
A range built for offices, public-access buildings, industrial sites, large volumes, damp environments and places with demanding aesthetic requirements.
Tranquillité
Thanks to the built-in black box, events can be analysed afterwards to better understand what triggered a fire alarm.
Fire detector comparison
Quickly identify the right detector for your building
Every environment has its own constraints: nuisance smoke, humidity, dust, large volumes, aesthetic requirements or sensitive plant areas. This comparison helps you quickly see why one detector suits better than another.

| Choose it if…The main use case to remember. | You have a standard building to protect simply and effectively. | You need finer detection through combined smoke and heat analysis. | You need dependable detection in an environment with nuisance smoke. | Your site is exposed to humidity, dust or corrosion. | You need to monitor a large volume or a great height. | You need to protect a place where looks matter as much as safety. |
| Recommended environmentsWhere this detector makes the most sense. | Offices, schools, hotels, public-access buildings, government buildings, standard commercial premises. | Hospitals, hotels, industrial kitchens, boiler rooms, areas near wet rooms. | Theatres, smoking rooms, airport terminals, industrial laundries, complex environments. | Factories, plant rooms, damp warehouses, swimming pools, industrial sites, dusty areas. | Warehouses, large halls, logistics spaces, monuments, high-rise buildings. | Museums, luxury hotels, head offices, historic buildings, premium offices. |
| Built-in technologyWhat the detector analyses to identify a fire. | Dual optical sensor for reliable smoke detection. | Two optical sensors plus a heat sensor to detect smoke and heat. | Two optical sensors plus a heat sensor and a carbon monoxide sensor. | Detection technology designed for harsh, demanding environments. | Long-range detection to cover large distances. | LOTA technology in a more discreet, better-looking format. |
| Key differenceWhat really sets it apart from the other models. | The safe choice for buildings with no particular constraints. | A fuller reading of the risk thanks to combined smoke and heat sensing. | CO sensing helps tell real combustion from a nuisance event. | It still performs where a standard detector reaches its limits. | It reduces the difficulty of installing and maintaining detectors at height. | It protects without spoiling the architecture or the interior feel. |
| Settings and adaptabilityHow well it adapts to operating constraints. | 4 sensitivity settings. | 16 operating modes. | 12 operating modes. | 18 operating modes. | Adjustable from ground level via a Bluetooth mobile app. | Suited to places where visual discretion comes first. |

| In shortThe line that helps you decide. | The dependable standard for everyday buildings. | The right choice when heat becomes a meaningful signal. | The best fit when real combustion has to be told apart from nuisance smoke. | The rugged choice for difficult environments. | The solution for covering long distances without repeated work at height. | The solution when safety has to stay out of sight. |
Torn between two detectors?
The choice depends not only on the type of detector, but also on your building, how it is used, the nuisance phenomena it may face and the applicable regulations. A DEF expert can help you identify the solution best suited to your site.
