5.0 EQUIPMENT UNDER TEST (EUT) DETAILS 5.1 EUT Description
The EUT is a DSP-based audio amplifier. It is intended for public address and general alarm systems. The EUT was in good working condition during the test, with no known defects.
The EUT is connected to a GENII-RC controller box. The controller box processes control inputs from various sources, monitors system faults, generates audio via integrated DSP, and activates broadcasts on connected amplifiers.
The EUT was grounded by the 3rd wire of AC Plug during the tests. The EUT is a Production sample. PCB part number images are below.
EUT Circuit Boards EUT Circuit Board Description Part Number
Processor Board 092019700250
Power Board 092018300090
5.2 Tested System Configuration
The system was configured for testing in a typical fashion. The EUT was placed on an 80-cm high, nonconductive test stand. The peripherals were placed on an 80-cm high, nonconductive test stand. The I/O cables and peripherals were unmodified, commercially available products. The excess lengths of the cables were bundled near the center of the cable with the bundles 30 to 40 cm in length. The testing was performed in conditions as close as possible to installed conditions. Wiring was consistent with
manufacturer's recommendations. Support and simulation equipment were remotely located during testing.
Support equipment was not subjected to the test requirements.

5.3 Operating Conditions of EUT
The EUT was in a normal operating mode during the tests. The controller was in constant communication with the external card and amplifier to ensure everything is functioning properly. All circuits were activated during the tests.
A Digital Input expansion board (P-16DIN-G) with a switch was connected to the amplifier. The switch was wired into one of the input channels on the P-16DIN-G board. This was to allow external devices to trigger events. The system was tested with the expansion board continously activating a broadcast tone of 1 kHz.
The audio output was connected to a variable load box.
Mode Description
Active A dedicated controller is in communication with the amplifier.
5.4 EUT Modifications
The following modifications were made to the EUT in order to comply with the requirements listed in this report: A Fair-Rite products Corp, Part number 0431164281, ferrite was added to the Audio output leads.
6.0 PERFORMANCE CRITERIA FOR IMMUNITY TESTS
The apparatus shall not become dangerous or unsafe as a result of the application of the required tests.
The performance criteria is classified as follows:
Performance Criterion A: The apparatus shall continue to operate as intended. No degradation of
performance or loss of function is allowed below a performance level specified by the manufacturer when the apparatus is used as intended. In some cases, the performance level may be replaced by a permissible loss of performance.
Performance Criterion B: The apparatus shall continue to operate as intended after the test. No degradation of performance or loss of function is allowed below a performance level specified by the manufacturer when the apparatus is used as intended. In some cases, the performance level may be replaced by a permissible loss of performance. During the test, degradation of performance is, however, allowed. No change of actual operating state or stored data is allowed.
Performance Criterion C: Temporary loss of function is allowed, provided the function is self recoverable or can be restored by the operation of the controls.
6.1 Minimum Performance Level
The minimum performance level as specified by the Federal Signal Corp. as follows: Both audio output channels must stay above 90 VAC and outputs must stay at 100V +- 10%. If an output level dropout occurs, the EUT must recover on its own within 10 seconds.
Criterion EUT specific acceptable performance for each Criterion
A The EUT must stay within tolerance during and after the exposure to the immunity signals. It shall remain fully functional during and after the tests.
B The EUT may show a degradation of performance but must return to normal after the exposure to the immunity signals with no user intervention.
C The EUT may show a degradation of performance or loss of function provided it can be restored by the normal operation of the controls, after the exposure to the immunity signals.
7.0 DEVIATIONS FROM THE TEST SPECIFICATIONS There were no deviations from the test specifications.
8.0 EXCLUSIONS FROM THE TEST SPECIFICATIONS There were no exclusions from the test specifications.
