Design Guide for the Polycom SoundStructure C16, C12, C8, and SR12
15 - 2
Thermal
• Thermal Dissipation (Btu/hr): 266 Btu/hr (C16), 230 Btu/hr (C12), 215
Btu/hr (SR12), 200 Btu/hr (C8)
• Operating temperature 0 - 40° C (104° F)
Operating temperature ranges for the three thermal sensors located on the
SoundStructure device are shown in the following table. These sensor values
are found on the Wiring page within SoundStructure Studio when connected
to a SoundStructure device. Green indicates normal operation up to the tem-
peratures listed in the following table. Yellow indicates an elevated
temperature that is acceptable but the ambient temperature and airflow in the
system should be checked. Red indicates an over-temperature event that must
be corrected for proper operation of the SoundStructure device.
