EN4232MR EchoStream® Receiver

Installation and Operation Manual - 05819C, April

4, 2011

1 Overview

Inovonics EchoStream technology is designed to minimize dead spots in

transmission areas using diversity reception and advanced signal

processing. The EN4232MR receiver allows you to add up to 32

transmitters and 12 outputs to any application, and includes a back tamper

for increased tamper security.

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 EN/

EE7016SK EchoStream® Survey Kit Installation and Operation Manual.

2 Power Cabling

Caution: Incorrect connections may cause damage to the unit.

Before beginning startup, you will need to connect power to the receiver. To

connect power to the receiver:

1. Connect power cabling to the Vs and GND connections.

• The power source must be 11-14 VDC. The power supply must be

unswitched, uninterrupted, and regulated.

• Use 14 - 22 gauge wire for all cabling, and ensure torque on the screw

terminals does not exceed 7 inch-pounds.
