The Notifier NFXI-BUNDLE is a bulk pack of 50 Opal NFXI-OPT addressable optical smoke detectors with 50 B501AP standard bases.
The NFXI-OPT has a built-in isolator and uses the light-scattering principle with a highly efficient detection chamber. Its processing includes smoothing filters to help eliminate transient environmental noise that can cause unwanted alarms. It is compatible with the Opal (159+159) and CLIP (99+99) protocols.
