EN1941 Family One-Way Binary RF Module
Installation and Operation Manual
1 Overview
EchoStream RF modules are designed to be easily interfaced with your
electronic remote application controller (RAC), allowing the assimilation of
any user-specific application into an EchoStream system. Once integrated
with existing products, RF modules provide you with complete EchoStream
functionality.
One-way binary RF modules are end-devices that use a logic-level
connection to interface with your RAC.

the jumper to select normally closed.
Note:
The EN1941 is shipped with the jumper unattached. With the jumper
unattached, the EN1941 defaults to normally closed.
Secondary alarm
Connects a secondary end-device to provide RF alarm
data for any user-specific application.
Primary alarm
Connects a primary end-device to provide RF alarm data
for any user-specific application.
Tamper input
Connects a tamper input to send a message when user-
specific end-device is tampered with.
Reset input
Connects a reset input to reset the one-way binary RF module
after a frequency band selection change or N/O - N/C selection change,
and to initiate an RF transmission.
Power
Connect power cabling to an external power supply of 2.6 to 5.5
volts.
Ground
Connects to ground.
Mounting hole
Used to mount the one-way binary RF module to the user-
