Clear-Com Tempest 900 - Power Connections; Powering on the Basestation

24 Tempest®900 4-Channel Wireless Intercom System
Power Connecons
The Tempest BaseStaon can be powered by AC or DC power, and uses an auto-switching power supply; therefore, if both
AC and DC are connected, the BaseStaon will automacally switch to DC in the event AC power is interrupted.. The front
panel ON/OFF switch controls AC and DC power coming into the BaseStaon. If AC and DC are both connected, the DC will
act as a power supply backup in the event AC power is interrupted.
AC Power Connecon
» Always connect the power cord to the Tempest BaseStaon before connecng to the outlet.
» Tempest BaseStaons are powered by an internal power supply. The cord to connect the internal power supply
to the mains supply must conform to the following:
» The mains power cord shall have an IEC C13 connector at one end and a mains power plug at the other end.
» An IEC C 13 plug has three pins, the centre pin carrying the earth/ground. The other two pins carry neutral
and live circuits.
» The conductors of the mains cords shall have adequate cross-seconal area for rated current consumpon of
the equipment.
» The mains plug that connects to the mains supply must be approved for use in the country where the
equipment is to be used.
» The mains power cord must be an IEC mains 3-wire grounding power cord complying with standard
IEC60320; IEC320/C13.
» Mains power cords used in the US must also comply with standard UL817.
» Only use AC power from 85 to 260 VAC at 50 – 60 Hz.
DC Power Connecon (Baery)
» To power the Tempest BaseStaon from DC power, you must provide an appropriate DC power input cable.
» The DC power input jack on the BaseStaon is a Switchcra 722RA.
» The mang plug is a Switchcra S760 - 2.1mm x 5.5mm power plug. The connector should be wired as center
posive.
» Always use appropriate wire of an acceptable gauge and length for your applicaon. The minimum
recommended wire is 26 gauge at not more than ve feet. If 10 feet is required, the minimum gauge would be
24.
» Only use DC power from 11 to 32 VDC. The Tempest BaseStaon will draw approximately 12 Was (990mA at
12VDC).
Powering ON the BaseStaon
Plug in the BaseStaon.
Turn the front panel ON/OFF switch to the ON posion.
The BaseStaon undergoes an inializaon cycle. During this power-up cycle, the LEDs ash and the LCD screen updates.
Approximately 4 seconds aer turning ON the power switch, you will see a splash screen showing the installed rmware
version. The splash screen lasts approximately 6 seconds before advancing to the normal Operaon screen. If connected to
a Local Area Network, the DHCP sengs (IP address, MAC address, etc) will then display unl MENU is pressed to escape or
unl the normal me out is completed. The system will then display the main Operaon screen and will be ready for use.
Note: When connecng/disconnecng a Remote Transceiver to the BaseStaon, be sure to power cycle the BaseStaon aer
re-connecng the Remote Transceiver. (When power cycling, turn o the power to the BaseStaon and wait 10 seconds
before turning it back on.) Failure to power cycle may result in errac operaon.
