The 1235SF and the 1235DF Fixed-location Transmitters provide singleand two-button activation, respectively. One light-emitting diode (LED) flashes with all transmissions, including supervision, to clearly show users when the unit is operating. The pendant can be mounted for fixed position signaling, adapting to a wide range of installations.
With the superior range and reliability offered by the Inovonics EchoStream platform, there is virtually no limit to the applications that can benefit from these pendants. The Inovonics EchoStream platform uses diversity reception and advanced signal processing to reduce dead spots in transmission areas.
System overview
Powered by Inovonics
The Inovonics EchoStream platform, powered by Inovonics wireless mesh network technology, ensures superior range, reliability, and scalability for commercial applications. Using a wide range of transmitters and repeaters, this proven technology
provides flexibility and performance to meet the most stringent requirements. This exclusive protocol is available only on Inovonics EchoStream products.
Wireless 900 MHz Band
The Inovonics EchoStream platform sends redundant information on several multi-frequency channels within the FCC Part 15 900 MHz band, providing superior range and reliability. In comparison, systems that use a single frequency technology can only send information on one narrow band channel. Any interference within the band can cause missed signals. With wireless registration, it is easy to add this technology to any application.
