EN4200 Security Only Serial Receiver
Installation Instructions
1 Overview
The EN4200 security only 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 Security Only 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.
• Do not mount wireless smoke detectors, co detectors, initiating device
transmitters or repeaters to removable surfaces, such as ceiling tiles.
• All products should be manually tested weekly.
• The EN4200 must be installed within 30 m (98.5 ft) of control unit.
• Low power transmitters shall be limited to a single initiating device.
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 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.
2.3 Select the Frequency Band
EchoStream products are able to use a range of radio frequencies, and are
shipped from Inovonics set for your geographic area.
• The jumper will be set on the two pins marked NZ to set the frequency
range to 921-928 MHz for New Zealand.
• The jumper will be set on the two pins marked AU to set the frequency
range to 915-928 MHz for Australia.
• The jumper will be removed to set the frequency band to 902-928
MHz for North America.
1. Ensure the frequency band is set for your geographic are.
2. If the frequency band is not set for your geographic area, place a
selection jumper on the appropriate frequency band selection pins to
select Australia or New Zealand, or remove it for North America.
Note: Only devices set for use in North America are configured for UL
installations.
3. If you have changed the frequency band and the device is powered on,
press the reset button to complete configuration.
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.
4. Use the provided anchors and screws to mount the serial receiver in a
location accessible for future maintenance.
5. Close the serial receiver housing.
