EN4216MR 16 Zone Multi-Condition
Receiver with Relay Outputs
Installation and Operation Manual
1 Overview
The EN4216MR receiver allows you to add up to 16 transmitters and five
outputs to any application, and includes a housing tamper for increased
tamper security.
The following add-on receivers are available from Inovonics:
* At least one relay must be used for faults to ensure the system is
supervised. More than one relay may be used, but that will deduct from the
number of alarm output relays.
1.1 Installing an Inovonics Security System
An EchoStream survey kit must be used to establish a UL 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 Wireless
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:

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.
