4B Universal Base

The 4B Universal Base contains no electronics and is suitable for indoor applications of the 614 series conventional (non-addressable), 814 and 850 series analogue addressable detectors.
It provides excellent space for cable access and terminations. It features remote LED connections and an anti-tamper facility. The 4B base is designed to snap-fit into the ceiling tile adaptor, or screw fix to the ceiling in the traditional manner. The 4B-6A Adaptor covers ceiling marks revealed when changing from an existing 5” or 6” base. The Euro Mount Adaptor is a shallow (20mm deep) back box for surface mounting applications. When (suitable) detectors are fitted in damp or dirty environments, the 4B-DHM Deckhead Mounting provides an IP55 seal between the mount and the detector base.
