<Installation position>
(A) Direct installation onto the ceiling with wood screws.
a
(B) Installation with accessory's bracket
(1) Drilling of the ceiling (ceiling opening)
Drill the receiver installation holes with the following dimensions at the ceiling position where
wires can be connected.
(A) Direct installation onto the ceiling with
wood screws.
(B) Installation with enclosed bracket.
(2) Wiring connection of receiver
Caution
Do not connect the wiring to the
power source of the terminal block.
If it is connected, printed board will
be damaged.
(3) Installation of the receiver
Remove the screw on the side of the receiver and sprit it into the upper case and lower
case.Install the receiver with one of the two installation methods (A) or (B) shown below.
(A) Direct installation onto the ceiling with screws
Use this installation method when the ceiling is wooden, and there is no problem for
strength in installing directly with wood screws.
Wall opening
①Put through the wiring from the back side to the hole of the lower case.
②Fit the lower case into the ceiling opening. Make sure that the clearance between
the convex part of the back of the lower case and the ceiling opening must be as
equal as possible on both sides.
③Using the two installation holes shown above, fix the lower case onto the ceiling
with the enclosed wood screws. (The other four holes are not used.)
④Connect the wiring with the wiring from the upper case by the connector.
⑤Take out the connector to the backside from the hole of the lower case putting
through the wiring at ①.
⑥Fit the upper case and the lower case, and tighten the screws.
(B) Installation with enclosed bracket
Use this method when installaing onto a gypsum board (7 to 18mm), etc.

①Catch the two protrusion of the enclosed bracket onto the tting as shown above,
and temporarily fix with the screws. (The bracket has an up/down and front/back
orientation. Con rm the top/bottom protrusion positions and the positional relation
of the ø 10 holes on the bracket and the installation hole on the lower case with the
above drawing.)
②Insert the end of the installation tting into the back of the ceiling from the opening,
and tighten the screws to fix the bracket onto the ceiling.
③Pass the wiring from the rear side through the hole on the lower case.
