u 15.2 m x 15.2 m(50 ft x 50 ft) coverage
u Automatic supervision of radio link
The EN1261HT PIR Motion Sensor Transmitter is
appropriate for commercial and high-end domestic
applications, providing the most cost-effective solution
for reducing installation expenses. The rounded cover
blends into the environment and is suitable for
different installation design needs. It also offers a
variable sleep time to extend the battery life in hightraffic applications. It is equipped with an integrated
sensor to meet the needs of every indoor installation.
Advanced signal processing recognizes human
signature size and movement, reducing false alarms.
Advanced microprocessor technology provides
excellent catch performance.
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
u Low power consumption
u Highly sensitive to moving infrared radiation
u Immunity to Radio Frequency Interference (RFI),
vibration, static, lightning, and ambient temperature
changes
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
Battery Sleep Time
Designed specifically for wireless applications, this PIR
has a maximum sleep time of 180 sec recommended
for most installations. The sleep time can be set to 15
sec or 30 sec for six activations before returning to its
180 sec sleep time. Setting the shorter sleep times
can shorten battery life.

Supervision
The cover tamper and battery activity are supervised.
Monitoring helps ensure reliable operation.
Wall and Cover Tampers
The optional wall tamper switch provides increased
security and is ideal for high end residential
applications. The wall tamper switch notifies the
system when the transmitter is removed from its
mounted surface. The cover tamper switch notifies the
system when an intruder attempts to remove the
sensor cover.
Pet Immunity
It is immune to pets up to 15 kg (33 lb) in weight and
30.5 cm (12 in.) in height.
