Detect fire earlier. Act faster. Protect more.

Aspirating Smoke Detection (ASD) systems continuously sample air to identify the earliest traces of smoke before a fire develops — ideal for data centers, warehouses, cleanrooms, heritage sites and other mission-critical environments where the earliest possible warning is essential.

Standards

AirSense aspirating detection. EN 54-20 and UL 268.

ModuLaser and MiniLaser are available in versions for European (EN 54-20) and North American (UL) specifications, so the same technology fits the standard your project calls for.

Incipient-Stage Detection

Very early warning — smoke is caught at the smoldering phase, before a fire develops.

ClassiFire® Adaptive Intelligence

Differentiates smoke from dust and airborne contaminants, minimizing nuisance alarms.

Modular, Flexible Design

Multi-zone, scalable systems that integrate seamlessly with BMS and fire systems.

Two ASD solutions, one goal

Earlier, smarter fire detection.

ModuLaser and MiniLaser are two complementary solutions designed to deliver reliable, very early warning smoke detection across a wide range of applications.

Flexible, modular ASD

ModuLaser

A high-performance, multi-channel aspirating smoke detection system developed for large-scale, complex and demanding applications. Its modular architecture extends the use of ASD far beyond traditional applications — from cleanrooms to industrial facilities.

Ultra-high sensitivity with advanced nuisance alarm rejection
Ideal for harsh environments (dust, airflow, industrial conditions)
Scalable multi-zone detection with modular architecture
Seamless integration with BMS and fire systems

Compact ASD

MiniLaser

MiniLaser brings very early warning smoke detection into a compact, cost-effective solution, ideal for applications where space, simplicity and efficiency matter most — from server rooms to heritage buildings.

Compact footprint for space-constrained environments
Fast and straightforward installation and configuration
Reliable early detection at a competitive cost
Flexible application coverage across a wide variety of spaces

What makes us different

Built around the same core principles.

Very Early Warning

Detection at the incipient stage, before a fire ever takes hold.

ClassiFire® Intelligence

Adaptive intelligence that minimizes nuisance alarms.

Modular by Design

Flexible system design tailored to each project’s requirements.

Advanced Filtration

Dust discrimination built for long-term reliability.

Installation Freedom

Detectors located in accessible service areas, not buried in ceilings.

Detect earlier. Act faster. Protect better.

AirSense detectors are extremely sensitive and capable of differentiating smoke from dust, significantly reducing false alarms while maintaining reliability — even in environments characterized by dirt, cold temperatures, humidity and large volumes, where traditional point detectors fall short.

Applications

Reliable detection in the harshest conditions.

From recycling plants and manufacturing facilities to correctional facilities where vandalism risk rules out conventional detectors, AirSense is engineered for environments where traditional fire detection struggles to operate effectively.

Data Centers

Very early warning detection protecting mission-critical infrastructure around the clock.

Warehouses

Reliable coverage across high-bay racking and large open storage volumes.

Recycling Centers

Built for dust, airflow and constant activity where conventional detectors struggle.

Manufacturing Facilities

Rugged detection engineered for harsh, high-activity industrial conditions.

High Atrium Spaces

Aspirating technology that performs reliably across large-volume open spaces.

Heritage Sites

Discreet, sensitive detection that protects irreplaceable buildings and collections.

Cold Environments

Dependable performance in cold temperatures and humidity where point detectors fall short.

Cleanrooms

Precise, low-nuisance detection for controlled, contamination-sensitive environments.
