clamps on the back side of the speaker and push downward on the plastic clamp to pop
the front grill off the CS651. Connect the Cat5 input cable and Cat5 output cable if
series connecting multiple speakers. If using the remote level port on the CS651
connect the Cat5 cable to this port at this time. Insert the CS651 into the opening with
the plastic clamps turned in as shown below.
Begin to tighten the installation screws. As you start to turn each screw the Angle Lug
Clamps (A) will rotate outward to engage the ceiling material (C).
CAUTION: Do Not Over Tighten the Clamps. Too much torque may snap off the lug,
causing the speaker not to seat securely. A snug fit is all that is necessary to assure
proper performance.
Remote Level Control
The CS651 allows the use of 3 options for remote level control. If a single CS651
speaker is to be controlled use ISP Technologies RM10 remote level control. The RM10
is designed to control a single Ceiling speaker and requires one Cat5 cable connection
between the CS651 and the RM10. The remote level control will allow adjustment of
the level of the CS651 from zero to the maximum level set on the Master Control
Module. The RM20 allows connection to two CS651 speakers and can control them as a
stereo pair or as dual mono speakers. The RM20i allows connection to two CS651
speakers as above but also includes a 1/8 inch input jack to connect to an iPOD or
other audio device. The figure below shows the connections with two CS651 speakers
and an RM20i Remote Level Control. Note: The CS651 ships with an RJ45 Jumper
plug inserted in the Remote Level Port, This jumper is required for audio to
pass if no remote level control is used. If connecting to a RM20 or RM20I
remove this jumper and connect the desired remote level control.
