EN4200 Security Only Serial Receiver
Installation Instructions
1 Overview
The EN4200 serial receiver is a security only gateway that uses reliable
frequency-hopping, spread-spectrum technology to decode radio
frequency (RF) transmissions from security end devices and high-power
repeaters, and then outputs the decoded data to the application controller
in a common serial data format. The EN4200 is used for security only
applications.
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: For more information about the EchoStream survey kit, see 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
services:
• E-mail: [email protected].
• Phone: [phone].
1.4 What’s In The Carton
• Two drywall anchors.
• Two mounting screws.
• Two pieces of mounting tape.
• One frequency band selection shunt.
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.

1.6 EN4200 EchoStream 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.
2.2 Select the Frequency Band
EchoStream products are able to use a range of radio frequencies, and
must be configured for your geographic area. This product ships with a
default frequency range of 902-928 MHz for use in North America. If you
are using the product in North America, skip to section 2.3, “Connect the
Serial Cable”; if you are using the product in Australia or New Zealand, you
will need to configure the EN4200 EchoStream serial receiver.
1. Use a small screwdriver to press the housing release tab; separate the
housing.
2. Place a selection jumper on the appropriate frequency band selection
pins.
• Place the jumper on the right two pins, marked AUS, to set the
frequency range to 915-928 MHz for Australia.
• Place the jumper on the left two pins, marked NZ, to set the frequency
range to 921-928 MHz for New Zealand.
3. If the serial receiver is powered on, remove and restore the power
source to reset.
2.3 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 serial receiver to ensure power
requirement is met for long cable runs.
4. Connect a serial cable to either the serial data port or the serial data
terminal. Cabling should meet the following specifications:
Cable requirements 4-conductor 20AWG (or larger) stranded-tinned
copper with PVC insulation rated to 300 volts at 60°C (140°F). (Belden
#8205, for example.)
Maximum cable length 30.5 meters (100 feet).
5. Route the cabling through either the bottom cabling knockout or the
side cabling knockout.
2.4 Mount the Serial Receiver
Caution: Mount the EN4200 EchoStream 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 EN4200 EchoStream serial receiver
is mounted in an easily accessible location for future maintenance.
6. Use the provided anchors and screws to mount the serial receiver in a
location accessible for future maintenance.
7. Close the serial receiver housing.

4 Television and Radio Interference
This equipment has been tested and found to comply with the limits for a
Class B digital device, pursuant to Part 15 of the FCC Rules. These limits
are designed to provide reasonable protection against harmful interference
in a residential installation. This equipment generates, uses and can
radiate radio frequency energy and, if not installed and used in accordance
with the instructions, may cause harmful interference to radio
communications. However, there is no guarantee that interference will not
occur in a particular installation. If this equipment does cause harmful
interference to radio or television reception, which can be determined by
turning the equipment off and on, the user is encouraged to try to correct
the interference by one or more of the following measures:
• Reorient or relocate the receiving antenna.
• Increase the separation between the equipment and receiver.
• Connect the equipment into an outlet on a circuit different from that to
which the receiver is connected.
• Consult the dealer or an experienced radio/TV technician for help.
