MRI-4001 SECUTRON

The Secutron MRI-4001 is a 6-inch low-profile, intelligent addressable detector mounting base engineered to interface Secutron 4000 Series detector heads (including the MRI-4010, MRI-4021, and MRI-4030) with the system's Signaling Line Circuit (SLC) loop.
It features a physical height profile of 0.625 inches and an open-style electrical terminal design that supports a solid or stranded field wiring range of 12 to 22 AWG. The base is built with standard mounting holes to securely fit single-gang electrical boxes,
3.5-inch octagonal boxes, 4-inch octagonal boxes, or 4-inch square boxes via an outer removable trim ring that neatly conceals the installation screw heads. Additionally, it features an integrated mechanical anti-tamper head
lock and incorporates a breakable, snap-out center plastic tab designed to be repositioned into the base's outer rim for visible on-site device address labeling.
