SC-9216R
SPEAKER LINE CHECKER
Operation
Operation
Operational instructions are divided into three main categories. The first category includes details required for
the initial setup and operation for a new system installation, or if changes have been made to an existing system.
The second category includes operational details for routine tests of an existing system. The third category
includes instructions to facilitate advanced capabilities that are not generally required in most applications.
Display images associated with these instructions may be found in the Display portion of this manual. The
corresponding image number(s) is listed after each step number [in brackets] that pertains to a display.
- INITIAL OPERATION
1. Switch OFF the AC mains (and/or DC power) to the SC-9216R using the power switch located on the front
panel. As a precaution, the system amplifier(s) should be switched OFF as well.
2. Terminate the amplifier output wires to an available channel on the SC-9216R via the screw terminals marked
“AMP IN”. Be sure to observe polarity (+/-) throughout the termination process.
3. Terminate the speaker input wires to the terminals on the SC-9216R marked “AMP OUT” which correspond to
the desired amplifier channel.
After these steps are completed, other system electronics may be switched ON and the system operated
normally. The SC-9216R will function properly with the amplifier(s) and/or other system components switched
OFF or ON.
4. Position the Channel Check switches in the desired position for each channel of the SC-9216R. The UP (OFF)
position means the channel will not be checked. The DOWN (ON) position means that the channel will be
checked.
5. Switch ON the AC mains to the SC-9216R. The display will flash the product description three times and then
indicate the Test Interval and time remaining until the next automatic test. In the event that an automatic test
occurs before step 6 see 5A.
5a. Do not interrupt a test. If the test completes without triggering a fault display or buzzer sound, proceed
with step 6. If a fault is found or the buzzer sounds, see step 5B.
5b. The BUZZER OFF button may be used anytime after the buzzer sound is no longer constant. The fault
indicator and associated Buzzer sound is in response to one or more channels testing differently than the
previously stored setting. Since the SC-9216R has not been set up for the system as currently configured,
the fault indication does not necessarily mean a fault exists. Proceed with step 6 once the test is complete
and FAULT FOUND is displayed.
6. Depress the OP MODE button several times to navigate to the MEMORY CLEAR display. Depress ENTER to
clear all previously stored settings. The display will indicate the test interval has been reset to 1 hour (the
factory default), followed by the product description, and also shows the time remaining until the next test.
7. Depress the OP MODE button as needed to navigate to one of the four ALL STORE modes that most closely
represent the system configuration, then Depress ENTER. The SC-9216R will automatically cycle through each
channel to establish a reference value for each channel. A clicking sound may be heard as the unit cycles
through each channel (relays opening and closing). Once completed, the Test interval and time remaining
until the next test will be indicated on the display.
8. Once the test interval and time remaining until the next test is indicated on the display, the test interval may be
changed as described in step 9.
