depth of the approximate 20mm, which is slightly deeper than the
base assembly. To semi-flush mount a special housing must be
used, which consists of a main assembly and a trim ring.

Insert the semi-flush shroud
assembly into the hole
in the ceiling tile.
Hold the semi-flush shroud
to the ceiling tile and tighten
the three screws to splay the
clamps to secure the shroud to the tile.
Locate the SenTRI Base into
the semi-flush shroud, such that the
two locating pillars on the
shroud feeds through the two
elongated holes on the Base.
Push the Base into the shroud
until the Base click locks into
the shroud.
Offer the trim ring to the shroud

clicks and goes no further. This will
lock the ring in position.
Fit the metal box onto the back
of the semi-flush shroud using the
appropriate fixing screws to secure
the box to the flush shroud.
Offer the SenTRI detector to the Base
and rotate the SenTRI detector
clockwise until it moves upwards into
