Applications

With a built-in POCSAG encoder, the paging transmitter is particularly suitable for non-simulcast networks in hospitals, public safety or other mission-critical applications.

The transmitter has a large installation base and offers industry-leading MTBF figures and a wide range of diagnostics and configuration options.

The transmitter can also be seamlessly installed in place of other transmitter brands in an existing paging network.

Specifications

Built-in Encoder    Accepts TNPP / TAP / iXO / PET protocols directly into the transmitter without the need for an external encoder.
Multiple Paging Protocols   The transmitter can be used with all industry standard POCSAG and FLEX paging formats (FLEX available on request).
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.
