Installation and Operation
TEST RUNNING: We urge you to test run these Servoreelers® prior to installation. Employing the short test cable that is supplied,
coonect each Servoreeler® directly to an output on the SRC controller. Use the master test station on the front panel to activate
functions; the DB multi-pin connector must be un-plugged to enable the front panel station to operate. The reeler is designed for
operation in a vertical position; when test running, hold the SRL-8 in a vertical orientation with the cable exit point facing down. An
internal spill sensor is employed to stop the reeler if it is operated with its cable impeded from down feeding freely. This interlock is
designed to prevent internal cable accumulation resulting in a possible jamming of the mechanism. Additional care should be
observed if the unit is operated horizontally. Bear in mind that this interlock is a back-up system, it is prudent to avoid
conditions that would overly rely on its intervention.
INSTALLING: The SRL-8 is provided with a 3.0” x 6.5” (76.2 x 165.1mm) mounting hole patern on its rear surface. These holes
are threaded to accept 8 –32 machine screws. The frame of the reeler is machined aluminum plate, some care is advised to avoid
stripping these holes. Prior to installing try the machine screws by hand to assure a proper fit. Screw length should be selected so
that no more than a nominal one half inch (.50”) extends into the rear plate. Two or more of these mounting holes must be utilized
for mounting. CAUTION Professional care and judgement must be exercised when mounting equipment overhead. Mounting
screws must engage a permanent, solid structural member or a metal bracket that is in turn securely attached to such a structure.
Should mounting against a wood beam or surface be required, sheet rock or wood screws may be employed from the inside,
through the threaded holes and into the structure; in this case all four holes must be used. If this surface is irregular, washers should
be employed to raise the center of the reeler back plate over these protrubances. Please note that although usually installed
above a ceiling, the contractor and the purchaser must assure that these devices do not pose a hazard to others, both
during and after installation.
OPERATION: Servoreelers® are operated by a remotely located controller. SRC controllers provide linear regulated 24vdc system
power. Operation is initiated by either pusbutton control or through interface with an external computer control system like AMX or
Crestron. IR sensors are employed to provide empty and full limits. An adjustable operating stop is also provided. This adjustable
stop operates from the deploy mode. After this preset stop is reached, re-start with a sustained down command to reach a lower
“service level”. Automatic or incremental operation is selectable. The automatic mode provides locked-in operation that is initiated by
a single “Deploy” or “Retract” momentary signal. The incremental mode facilitates fine positioning by allowing the Servoreeler® to
respond to individual, incremental, commands. Test running as described below, should always be performed in the incremental
mode.
SETTING OPERATING STOP POINT: The IR sensor that controls the length of cable deployment is mounted on an adjustable arm.
To access this adjustment; loosen the four cover screws about two turns and slip the cover up from the body of the Reeler. To the
lower right of the cable storage reel, you will see a wedge shaped bracket with a curved adjustment slot and locking thumbscrew.
The Reeler is shipped from our factory set to maximum deployment. To reset, loosen the locking screw just enough to enable the
bracket to be moved; utilizing the screw as a pointer, push on the bracket utilizing firm finger pressure to re-locate the sensor to a
new position. Activate the down mode to test the new stop point; repeat until desired length of deployment is achieved. Gently
tighten the lock screw to retain the setting.
CEILING BEZEL OPERATION: A switched ceiling bezel assembly (BZ-1) can be employed with the SRL-8. When the BZ-1 is used,
a white delrin slide assembly containing an activating magnet will be installed on the cable above the microphone. This assembly
along with a dust cap simply slip into the top of the installed bezel. Please refer to the BZ-1 installation sheet for complete
instructions. NOTES: (1) When installed with a bezel, take care not to set the retraction speed at the controller at a rate that is so
rapid that it results in a bypassing the bezel limit switch. (2) If possible, install the SRL-8 with the cable exit point at least eight inches
above the top of the ceiling tile. This is to assure that the bezel switch activates before the internal up limit switch. If overhead
clearance does not permit this spacing and the microphone stops before fully docking into the bezel, you can shorten the exposed
cable lead length. With the cover removed, locate the multi-turn trimmer under the right side of the printed circuit control board.

Using a long thin screwdriver or preferably if available, an insulated trimmer adjustment tool; turn counter-clockwise to shorten the
cable lead; clockwise to lengthen.
