Numens -Â Model 401-001 -non-addressable ultraviolet flame detector
The 401non-addressable ultra-violet flame detectors are suitable for connection to 2-wire and 4-wire non-addressable fire detection control and indicating equipment, or to addressable fire detection control and indicating equipment that can accept non-addressable type detectors . The 401 UV flame detectors are suited to applications where flames rapidly develop due to thenature of the combustible materials, such as where petrochemical products are used or stored. The 401UV flame detector provides fire detection and alarm system designers with a Standards-compliant detector for life safety and property protection applications.The 401non-addressable ultra-violet flame detectors are suitable for connection to 2-wire and 4-wire non-addressable fire detection control and indicating equipment, or to addressable fire detection control and indicating equipment that can accept non-addressable type detectors[1].
