u Programmable as normally‑open (NO) or
normally‑closed (NC)
u Small unobtrusive design
u Fully supervised
u Includes screw‑closure housing, cover tamper, wall
tamper
u Includes EOL resistor
These universal transmitters can make most
normally‑open (NO) or normally‑closed (NC) sensors
into wireless devices. The transmitters work with
shock sensors, holdup buttons, pressure mats,
temperature sensors, status relays, and other devices.
They are designed for installations that require more
security. They are fully supervised and include
screw‑closure housings, cover tampers, and wall
tampers.
This line of universal transmitters includes:
• EN1215EOL Universal Transmitter with Wall Tamper
and EOL Resistor
• EN1215WEOL Universal Transmitter with Wall
Tamper, Reed Switch, and EOL Resistor
The Inovonics EchoStream platform uses diversity
reception and advanced signal processing to reduce
dead spots in transmission areas. The transmitters
have superior range and reliability, and are ideally
suited for commercial or residential installations.
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.
Functions
NO or N/C Operation
The universal transmitters work with any standard NO
or NC contact (15 ms duration) or sensor.
Supervision
The cover tamper, wall tamper, and battery activity are
supervised. Monitoring helps ensure reliable
operation.
