3.11: FAA-500-CB built-in housing
The FAA‑500‑CB Built-in Housing is used for the installation of the detector into concrete
ceilings. It allows for easy connection of conduits.
The FAA-500-CB Built-in Housing is placed on the concrete form, fastened and secured against
floating. During fastening make sure the nails are located in the area of the Styrofoam, to
prevent interference when cutting the Styrofoam.
Pipe or cable inlets at the FAA‑500‑CB Built-in Housing within the wall areas are made with a
universal cutting tool. After removing the form-boards, the front part
(1)
is opened with a fret-
saw or hole saw.
Into the hole of the built-in housing, a FAA‑500‑BB Ceiling Mount Back Box is then inserted
which takes base and detector.
