EN4000 Universal Serial Receiver
Installation Instructions
1 Overview
The universal serial receiver is a wireless gateway between EchoStream
one-way transmitters (security, submetering, temperature, or analog) and a
head end application using an RS-232 serial interface.
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.
Note: Inovonics offers two options for site surveys: the EN7017 survey kit
and app and EN4016SK survey receiver. The EN4016SK survey receiver
displays the decibel level, while the EN7017 survey kit and app displays
only that the reception is good or weak. For more information, see the
EN4016SK Survey Receiver Installation and Operation Manual or the
EN7017 Survey Kit and App Installation and Site Survey Instructions.
Caution: The EchoStream system should be tested regularly to ensure
operation. To test: place the system in test mode, activate an end device,
and ensure an appropriate response.
1.2 RF Signal Propagation
While wood, drywall and glass usually let the RF signals pass, some
materials may inhibit or attenuate radio frequency (RF) signal propagation
by blocking, reflecting, deflecting or absorbing RF signals.
Consider anything between transmitters and repeaters and/or the receiver.
Is there concrete and steel construction? Are there earthen berms or hills?
Are there a lot of trees? Devices should be mounted such that they are
least affected by these elements.
For best results, transmitters and repeaters should be mounted at the
optimal height to achieve line of sight to repeaters and/or the receiver.
Usually this means they will be mounted as high as possible.
Following are some typical obstacles to RF signal propagation:
1.3 Inovonics Contact Information
If you have any problems with this procedure, contact Inovonics technical
support:
• E-mail: [email protected].
• Phone: [phone].
Material Affect Recommendation
Metal construction, including
ductwork; pipes; studs;
stucco, plaster or concrete
with wire mesh; satellite
dishes, metal-lined rooms
such as walk-in coolers or
freezers; metal siding, safes,
etc.
Can reflect, absorb
and/or disrupt RF
signals.
Perform a site survey
using an Inovonics
wireless survey kit to
verify the RF signal is
acceptable, and, when
necessary, to determine
where to locate
repeaters.
Completely enclosed metal
boxes/enclosures.
Can restrict RF
signals.
Solar panels, cinder block
walls, windows with built-in
solar tinting.
Can absorb and/or
reflect RF signals.
Vegetation. Can attenuate RF
signals. The RF
environment can
alter as trees shed
or sprout leaves.
Add repeaters as issues
arise.
Automobile and truck traffic. Can disrupt RF
signals.
Mount Inovonics devices
at a height sufficient to
achieve line of sight
above traffic.

1.5 EN4000 Universal Serial Receiver Operation LEDs
The following LEDs are used to monitor serial receiver operation:
Transmit LED: Lit when the serial receiver is transmitting data to the
application controller.
Receive LED: Lit when the serial receiver is receiving data from the
application controller.
Decode LED: Lit when the serial receiver is decoding an RF transmission
from another Inovonics device.
2 Installation and Startup
2.1 Installation Notes
• These products are designed to be maintained by professional
security technicians.
• Products are tested for indoor use.
• All products should be manually tested weekly.
• Each manually operated holdup alarm initiating device shall be
installed so that it cannot be observed by the public and so that it can
be operated in a manner that will not be obvious to an attacking party.
• Each semi-automatic holdup alarm initiating device shall be installed
so that it is not noticeable to an attacking party during a holdup
attempt and is not noticeable to the public or an attacking party prior to
a holdup attempt.
2.2 Connect the Serial Cable
Caution: Long cable runs should not be adjacent to high current power
feeds. Keep cable lengths as short as possible to minimize cable
capacitance. Measure voltage supply at the universal serial receiver to
ensure power requirement is met for long cable runs.
1. Connect a serial cable to either the serial data port or the serial data
terminal. Cabling should meet the following specifications:
• Four-conductor 20AWG (or larger) stranded-tinned copper with PVC
insulation rated to 300 volts at 60°C (140°F). (Belden #8205, for
example.)
2. Route the cabling through either the bottom cabling knockout or the
side cabling knockout.
Note: All field-wiring circuits that derive energy from power sources
connected to a control unit shall be power limited. Route the cabling
through the side cabling or back housing knockout.
2.3 Mount the Universal Serial Receiver
Caution: Mount the EN4000 universal serial receiver in a location removed
from metal. Metal objects (duct work, wire mesh screens, boxes) will
reduce RF range.
Note: A best practice is to ensure the EN4000 universal serial receiver is
mounted in an easily accessible location for future maintenance.
1. Use the provided anchors and screws to mount the serial receiver in a
location accessible for future maintenance.
2. Close the serial receiver housing.
3. Perform a walk test, activating each transmitter assigned to the receiver
and ensuring a good signal.
Caution: Always test the system for operation upon completion of the
installation.

Problem Possible Solutions
Receiver won’t power up. • Verify your power and ground wires
are securely connected to VS and
GND on the power terminals.
• Meter incoming power to make sure
it is operating at 10-14 VDC, 55-
90mA.
• Keep cable lengths as short as
possible to minimize cable
capacitance. Measure voltage
supply at the receiver to ensure
power requirement is met for long
cable runs.
Messages from registered transmitters
are not being received.
• Verify receiver is getting enough
power.
• Bring the transmitter close to
receiver to verify it is in range and
can be heard by the receiver.
