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,

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.
