Summary
The AirSense MiniLaser (9-30501) is a compact, single-zone aspirating smoke detector (ASD) built for sites that need high-sensitivity, early-warning fire detection without a bulky footprint. Whether you’re protecting a server room, a heritage building or a compact plant space, it’s designed to draw air samples through a pipe network and detect incipient fires before they produce visible smoke.

For you on site, that means fewer callbacks for false alarms, faster commissioning, and a detector that scales from simple DIP-switch setups to more complex pipe designs without swapping hardware. The EN54-20 certification and CPR compliance also give you a straightforward story for sign-off on commercial fire installations.
It delivers this through laser-based forward-scattering detection paired with ClassiFire technology, which continuously adapts sensitivity to the environment to hold alarm stability over the product’s life. A docking station design keeps the sensitive electronics protected during first fix, and front-accessible wiring terminals let you test and maintain the unit live, without powering down or dismantling it.
Features
- Dual configuration – set up simple pipe layouts with DIP-switches or model complex networks in PipeCAD from a laptop
- Flexible module placement – fit the display and expansion sub-modules on either side of the detector to suit your wiring route
- Up to two functional modules – add capacity in the expansion sub-module without a separate enclosure
- Docking station design – remove the sensitive electronics during first fix so they aren’t damaged on site
- Quick-fit pipe adaptor – locks down securely while leaving room for fast pipe connection and removal
- Bar graph smoke display – gives an at-a-glance view of smoke level development alongside standard alarm and fault icons
- ClassiFire adaptive sensitivity – continuously adjusts to environmental conditions to hold alarm stability and cut nuisance alarms
- Continuous airflow monitoring – flags blocked sampling points, broken pipes and abnormal flow before they become a fault call
- USB-C interface – handles advanced diagnostics, configuration and firmware updates from a laptop
- Front-accessible wiring terminals – carry out live testing and maintenance without powering down or dismantling the detector
- Embedded PipeCAD file storage – keeps the design on record even if the original documentation goes missing
- 10/90 waste-gate airflow with multi-layer dust filter – protects the optical chamber and extends maintenance intervals
- 20,000-event log and chart recorder – gives you long-term performance data for reporting and handover
FAQ
Yes. For simple sampling pipe layouts, the DIP-switch interface lets you set key configuration on site without a PC. For more complex pipe networks, you’ll need PipeCAD modelling on a laptop connected via the USB-C port. The MiniLaser supports up to 125m of combined sampling pipe per detector module, with sampling hole counts of up to 10 for Class A, 20 for Class B or 35 for Class C, depending on the classification you’re designing to. Yes. The expansion sub-module accepts up to two functional modules, such as the 9-30521 Input/Output functional module, and can be paired with the 9-30520 expansion housing if you need to add capacity beyond the base unit. No. The MiniLaser carries an IP40 rating and is specified for indoor use only, so it should be sited within a protected environment rather than exposed plant areas. It’s certified to EN54-20 and CPR compliant, which supports its use in commercial fire detection installations under BS 5839-1. Always confirm the specific pipe design and installation meet local approval requirements, as coverage area is subject to these. Yes, all wiring terminals are front-accessible, so you can carry out live testing and routine maintenance without dismantling or de-energising the detector. For anything beyond routine checks, refer to the full installation and service manual.Can I commission the MiniLaser without a laptop?
