EN4204R Four Zone Add-On Receiver with
Relay Outputs
Installation Instructions
1 Overview
The EN4204R four zone add-on receiver with relay outputs allows you to
add up to four transmitters to any application. With diversity reception and
advanced signal processing, Inovonics’ EchoStream technology is
designed to minimize dead spots in transmission areas.
1.1 Installing an Inovonics Security System
An EchoStream survey kit should be used to establish an EchoStream
system. The EchoStream survey kit measures the signal strength of high-
power repeater and sensor messages to help optimize your EchoStream
system.
Figure 1 Sample EchoStream system
The EchoStream survey kit provides you with two signal strength
measurements: signal level and signal margin.
Signal level
The signal level is the measurement of the overall decibel level of the
message.
Signal margin
The signal margin is the measurement of the decibel level of the message,
minus the decibel level of any interfering signals. Inovonics equipment
should be placed within a facility such that all end-devices produce signal
margin readings of at least 4 decibels.
Both the signal level and signal margin are measured in decibels. Because
signal strength and signal margin are measured on a logarithmic scale, the
difference between a decibel level of 3 (Weak) and a decibel level of 4
(Good) is a much larger difference than it would be on a linear scale.

Outputs LEDs
Most of the LEDs and buttons perform different function depending on
which mode the the receiver is in. By default the LEDs are in operation
mode; to enter diagnostic mode, press the advance button.
Operation LEDs
Alarm LED: Lights when any transmitter is sending an alarm transmission.
Tamper Fault LED: Lights when any transmitter is sending a tamper
transmission.
Low Battery Fault LED: Lit when any transmitter has a low battery.
Inactive Fault LED: Lit when any transmitter is inactive.
Power LED: Lit when receiving power.
Transmitter Number LEDs: Lit when the transmitter is in alarm.
Decode LED: Flashes when any recognizable transmission is received.
This LED is only visible when the pry-out door or cover is removed.
Diagnostic LEDs
Alarm LED: Lights when the selected transmitter is sending an alarm
transmission.
Tamper Fault LED: Lights when the selected transmitter is sending a
tamper transmission.
Low Battery Fault LED: Lit when the selected transmitter has a low battery.
Inactive Fault LED: Lit when the selected transmitter is inactive.
Power LED: Lit when receiving power.
Transmitter Number LEDs: Shows status of the transmitter assigned to that
number when lit. Use the advance button to scroll through transmitters.
Advance Button: Scrolls through transmitters to display status.
Decode LED: Flashes when any recognizable transmission is received.
This LED is only visible when the pry-out door or cover is removed.
