1- AC Power Input Connector
The IEC AC Power Input Connector accepts the AC power cord. Use this connector with the supplied AC power cord to
power the Tempest BaseStation from AC power between 85 and 260 VAC at 50 – 60 Hertz. The BaseStation will draw
approximately 15 Watts (125mA at 120VAC, 65mA at 230VAC).
2- DC Power Input Connector
The DC Power Input Connector accepts a Switchcraft S760 2.1mm x 5.5mm power plug wired as center positive. Use this
connector with a user-supplied cable to power the Tempest BaseStation from DC power (battery) between 11 and 32 VDC.
The BaseStation will draw approximately 12 Watts (990 mA at 12VDC).
3- Intercom Channel A/B Connectors
The Intercom Channel connectors (A/B) allow the user to connect the Tempest BaseStation to 2-Wire external intercom
systems or other Tempest BaseStations. The XLR-3M/F 2-Wire intercom connectors interface with Clear-Com, RTS, Balanced
and other compatible intercom systems. The pairs of XLR3-M and XLR-3F are electrically identical.
4- RJ-45 4-Wire Intercom A/B Connectors
The RJ-45 4-Wire Intercom connectors (A/B) interface with 4-Wire intercom systems and devices including Clear-Com
matrix systems. This is an intercom audio-only connector and does not support data transfer. The connector is balanced
and transformer isolated. Nominal line levels are -18 to +4 dB (IN) and -6 to +12 dB (OUT).
