The detector works continually drawing air into sampling holes pipe
network. This information
can then passed onto their fire service company, ensuring that service
technicians arrive onsite fully prepared. Should fault
occur, the user simply opens the field service door and activates the Instant
Fault Finder feature determine the specific fault condition.
