STI’s RFI Series Paging Transmitters2019-08-13T04:36:29+00:00

The RFI series transmitter is suited for applications in city and statewide paging systems for commercial, health and emergency services usage where reliable simulcast overlapped coverage is critical.

The transmitter can be used as a standalone unit for covering a campus or building, or as a part of a large wide-area network with almost any paging terminal vendor. The transmitter can also be seamlessly installed in place of other transmitter brands in an existing UHF paging network.

Transmitters provide 20-250 Watt continuous duty power output for 138-174 MHz and 929-932 MHz Bands for digital paging systems. Supports POCSAG and Flex paging protocols.

Designed to match the Prism-IPX ipBSC transmitter controller interface, the RFI allows full remote control, monitoring, alarming and remote software management using the Prim-IPX OMI Network Management System.

Specifications

Multiple Paging Protocols
The transmitter can be used with all industry standard POCSAG and FLEX paging formats.

Output Sniffer Port
A separate port with output power relative to the transmitter output allows a diagnostics module to check the outgoing RF message for integrity and transmit power level.

Absolute Delay Correction
The transmitter absolute delay setting can be configured for multisite networks to account for different upstream paths from the paging terminal to the transmitter sites.

Frequency Offset
Configurable frequency offset allows for multi-site frequency planning to eliminate ‘zero beating’ and RF nulls.

Remote Diagnostics
Windows™ software allows remote Ethernet connection to the transmitter for configuration, diagnostics and firmware upgrade.Smart Protection
Configurable alarm thresholds and transmitter actions allows user configurable levels of automatic protection for on-site equipment.

Integrated Isolator
Integrated fan cooled and temperature controlled isolator means a damaged or missing antenna system can be remotely diagnosed.

Reliability
Superb environmental control, improved amplifier efficiency, and a design optimized for reliability make the RFI-148-250 one of the most reliable high-powered paging transmitters available.
