The Earliest Possible Warning for Your Most Critical Assets
In some environments—such as data centers, telecommunication rooms, or cold storage facilities—a standard smoke detector is simply not enough. In these places, the cost of damage and downtime is so immense that detection at the earliest incipient stage of a fire is non-negotiable. For this need, Kidde ModuLaser® presents, a state-of-the-art Aspirating Smoke Detection (ASD) system.
ModuLaser is not a passive detector; it actively “sniffs” the air to find the very first signs of a fire, long before smoke is visible to the human eye.
Kidde ModuLaser – Aspirating Smoke Detection: How Does It Work?

Unlike a spot-type detector that waits for smoke to reach it, an ASD system works proactively:
- Air Sampling: A network of small pipes with precisely engineered sampling holes is installed throughout the protected area.
- Active Aspiration: A near-silent fan (aspirator) in the main detector unit continuously draws air from the room through these pipes.
- Laser Analysis: This air sample is then passed through a highly sensitive laser detection chamber, which is capable of identifying microscopic, invisible smoke particles.
- Staged Alerts: The system can be programmed to provide multiple alarm levels (e.g., ‘Alert’ and ‘Action’), giving personnel time to investigate before drastic fire suppression measures are required.
Kidde ModuLaser – The Main Advantage: Very Early Warning
The greatest benefit of the ModuLaser system is its ability to detect a fire at its incipient stage. This is the phase where materials begin to overheat and release invisible particles, long before there is actual smoke or flame. This very early warning provides invaluable time to:
- Investigate and prevent a fire from ever occurring.
- Conduct an orderly evacuation.
- Activate suppression systems in a controlled manner.
Kidde ModuLaser – The ModuLaser Design: Flexible and Scalable
The name “ModuLaser” reflects its two key features:
- Laser: It uses laser-based detection technology for the highest sensitivity.
- Modular: Its modular design is highly innovative. You can link multiple detector modules together into one seamless system, controlled from a single display module. This allows the system to be easily expanded as your facility’s needs grow.
Ideal for the Most Challenging Environments
ASD systems like ModuLaser excel in areas where standard detectors are ineffective:
- Data Centers & Server Rooms: Where high airflow can blow smoke away from standard detectors.
- Cold Storage: The detector unit can be located outside the freezer, while the pipes sample the cold air inside.
- High-Ceiling or Inaccessible Areas: Such as atriums, warehouses, or elevator shafts.
- Aesthetically Sensitive Areas: Museums or historic buildings where the tiny sampling holes are nearly invisible.
In conclusion, the Kidde ModuLaser is more than a smoke detector; it’s a very early warning air-sampling system. Its unparalleled sensitivity, reliability in challenging environments, and modular design make it the ultimate choice for protecting mission-critical assets where downtime is not an option.
