The Tempest900 4-Channel BaseStation is a Frequency Hopping Spread Spectrum (FHSS) digital wireless intercom system operating in the 902 to 928 MHz band ensuring comprehensive coverage and wide reach while offering high resistance to multi-path interference. The front panel LCD display provides real time status including battery monitoring of active BeltStations and easy access to the hardwire intercom settings and levels. Each BaseStation is capable of Call and Remote Mic Kill.

The Tempest900 BaseStation is supplied with a single omni-directional antenna (RP-TNC RF connector). On the rear is a RJ45 connector for a (optional) Remote Transceiver. The Remote Transceiver can be located up to 1500ft (450m) away from the BaseStation over CAT-5/6 cable with no loss of RF signal. The CAT-5/6 cable also supplies power to the remote transceiver. An additional RJ-45 enables remote monitoring and control of the entire wireless system over a Local Area Network (LAN) with the aid of the Tempest T-Desk software.

The Tempest900 BaseStation connections include a 2-wire or 4-wire interface with M/F 3-pin XLR loop thru and one 4-wire RJ45 port per channel. The 2-wire interface is compatible with Clear-Com®, RTS®, and Telex® intercom systems, and includes an auto-null circuit.

Three modes of operation are available within each Tempest BaseStation: Normal, Shared, and Split. This feature allows from 5 users to hundreds of users depending on configuration.

Utilizing the Tempest system TDMA technology and proprietary Accu-Sync synchronization, up to (5) 900 BaseStations and 25 full-duplex wireless BeltStations (in Normal Mode) can be used simultaneously. By switching to Shared or Split Mode, an unlimited number of BeltStations can be registered to each BaseStation using shared resources.

The Tempest900 BaseStations handle work zone transitions with iSelect on-command roaming technology. Accessing iSelect through the 900 BeltStation LCD user interface allows a user to easily change their association with another BaseStation location in just a few seconds.
