EE1941/EN1941 One-Way Binary RF Module
Installation and Operation Manual - 06287E
1 Overview
EchoStream RF modules are designed to be easily interfaced with your
electronic remote application controller (RAC). RF modules allow the
assimilation of any user-specific application into an EchoStream system.
Once integrated with existing products, RF modules provide you with
complete EchoStream functionality.
E*1941 one-way binary RF modules are end-devices that use a logic-level
connection to interface with your RAC. E*1941 one-way binary RF modules
can be used in either one-way or two-way EchoStream systems.

The E*1941 is a universal one-way binary RF module with two alarm input
pins, allowing the use of dual inputs. Input one is the primary alarm, bit 0;
input two is the secondary alarm, bit 1.
There are two models in the E*1941 product family.
• The EN1941, for 900 MHz applications in North America, New
Zealand, and Australia,
• The EE1941, for 868 MHz applications in Europe

Frequency band selection pins (EN1941 only) Place a jumper to select the
frequency band for your geographic area.
• Place the jumper on the left two pins to select 915-928 MHz for
Australia.
• Place the jumper on the right two pins to select 921-928 MHz for New
Zealand.
• Leave the jumper off the pins to select 902-928 MHz for North
America.
ES selection pins (EE1941 only) To enable compatibility with ES products,
place a selection jumper on the ES selection pins; if no ES products are
used in your system, remove the selection jumper.
N/O selection pins Place a jumper to select normally open inputs; remove
the jumper to select normally closed.
Note: The E*1941 is shipped with the jumper unattached. With the jumper
unattached, the E*1941 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 2.4 to 5.5
volts.
Ground Connects to ground.
Mounting hole Used to mount the one-way binary RF module to the user-
specific product. The mounting hole should only be used with a nylon
standoff, never metal.
LED contacts Use to control an LED switch. Not designed to drive LED
power.
Board stabilization holes Used to mount and stabilize the board. The board
stabilization holes should only be used with non-metal standoffs.
