Compact Aspirating Detection for Demanding Applications
The MiniLaser is a compact, single-zone aspirating smoke detector designed for applications that demand high sensitivity, advanced diagnostics, and flexible configuration. Built on proven ModuLaser technology, it delivers reliable early warning while maintaining a small footprint suitable for a wide range of installations.
High Resolution Detection with Intelligent Alarm Stability
MiniLaser uses laser-based forward-scattering optical detection, optimized for identifying extremely small particles associated with incipient fires. With very high optical resolution and multiple independent alarm levels, it supports early intervention while maintaining operational reliability.
The integrated ClassiFire technology continuously adapts sensitivity based on environmental conditions, ensuring long-term alarm stability and minimizing nuisance alarms throughout the detector’s lifecycle. This intelligence maximizes early warning performance without increasing false alarm risk.
Designed for Fast Installation, Commissioning, and Service
MiniLaser is engineered to simplify every stage of deployment. Modular placement of the user interface and expansion modules allows flexible physical installation, while pre‑installation backplanes enable wiring to be completed early in the project lifecycle.
Commissioning is accelerated through a DIP‑switch interface, enabling key configuration settings without a PC, while a USB-C interface supports advanced diagnostics, configuration, and firmware updates. All wiring terminals are front-accessible, allowing live testing and maintenance without powering down or dismantling the detector, significantly reducing service time and disruption.
Long Term Operational and System Integrity
MiniLaser delivers sustained value through features that enhance reliability, traceability, and lifecycle performance. Continuous airflow monitoring detects blocked sampling points, broken pipes, and abnormal flow conditions, while event logging and chart recording provide long-term visibility of system performance.
Embedded PipeCAD file storage ensures full design traceability over time, even when original documentation is unavailable. The 10/90 waste-gate airflow architecture and multi-layer internal dust filter extend maintenance intervals, protect the optical chamber, and support consistent detection performance over the product’s lifetime.
Key features: - Dual Configuration :
Dip-switch configuration setting for simple sampling pipe layouts or PipeCAD modeling for more complex sampling pipe with laptop configuration
- Customizable:
Display sub-module and Expansion sub-module can be located most conveniently based on wiring needs, on either side of the detector module. Subjected to the specific requirements of the application, up to 2 functional-modules can be installed in the expansion sub-module
- Simplified installation :
Ingenious docking station design allows detector to be easily installed. Sensitive electronics are easily removed to ensure they will not be damaged during first fix installation. Aspirating pipework and cable entries can easily be made into either the top or the bottom of the unit.
- Intuitive user interface :
Easy to understand icon driven UI, providing status of faults and alarms. With the addition of a bar graph display showing smoke level development in the protected area.
- Easy pipe connection :
The quick fit pipe adaptor system locks down securely, yet leaves plenty of room for easy pipe connection and removal.
- Easy maintenance:
Access to all wiring terminals for easy diagnostics while the unit is fully operational. Additionally a local reset button is provided which can be used during commissioning and maintenance. To further simplify maintenance, the MiniLaser and ModuLaser use the same interal filter.
