Detection up to 800m2

The LaserCOMPACT detector has been specifically designed to provide all the benefits of aspirating smoke detection, including very early warning, in single environment small areas and where space is a premium. This has been achieved through the combination of approved LaserPLUS detection technology, dual-stage air filtration technology and a modified aspirator design incorporated into a smaller enclosure with a simplified display. LaserCOMPACT is available in two main versions, one that interfaces via relays only (RO) or via the relays and VESDAnet (VN).


The LaserCOMPACT is made up of two parts: the main enclosure and the front cover.

The main enclosure houses all the key components of the detector. All non-serviceable items like the main processor board and detector chamber are mounted away from the general access area, protecting them during the installation and service process.


The main enclosure includes:

  • Laser Detection Chamber
  • Main processor board with integrated flow sensor card
  • Single air inlet port with air flow monitoring device
  • Termination Card supporting three relays
  • Fire
  • Pre-alarm
  • Alert/Fault
  • (including service and Isolate)
  • The card also includes power connections and VESDAnet communication connection on the (VN) version
  • LaserCOMPACT Aspirator
  • Dual-Stage Air Filter Cartridge
