EN4216MR EchoStream® Receiver

Installation and Operation Manual - 05637D, April
4, 2011

1 Overview

The EN4216MR receiver allows you to add up to 16 transmitters and six
outputs to any application. With diversity reception and advanced signal
processing, Inovonics EchoStream technology is designed to minimize
dead spots in transmission areas.

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

Output LED: Lights when any transmitter output is active.
Fault LED: Lights when any transmitter is sending a fault condition.
Power LED: Lit when receiving power.
LCD Display: Shows status, event log and programming information.
Decode LED: Flashes when any recognizable transmission is received.
This LED is only visible when the cover is removed.
Up button: Scrolls the display up.
Down button: Scrolls the display down.
Back button: Returns display to the previous menu, or when pressed in
the main menu options, returns the unit to normal operating mode. When
entering information in the display, returns to the last character entered.
Enter button: Selects the currently displayed menu item. If in normal
operating mode, sets the unit to menu mode.
Reset button: Clears the current status for all points and resets all outputs
and LEDs. Records a receiver reset entry in the event log and resets the
supervision window timers. This button is only accessible when the cover is
removed.

2 Power Cabling

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.

• Power source should be 11-14 VDC. 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.

• For UL installations, wire lengths must not exceed 300 feet.
