4.2 EN4200 Receiver Supervision
The commercial wireless interface module supervises
the Bosch
EN4200 receiver by periodically polling it. If the
EN4200 does not respond to the polls over a
165-sec period, the commercial wireless interface
module will initiate a Point Bus Trouble event back to
the control panel. The control panel will then initiate a
Point Bus Fail 1 (or 2) event.
If this occurs, the keypad shows Figure 21.

Enter a valid password. The keypad shows Figure 22.

4.3 Missing RF Transmitters
A transmitter may go missing in the system due to the
following most common reasons:
• Dead battery
• Physical environmental changes
• Damage to the transmitter
The keypad shows Figure 21.
Enter a valid password. The keypad shows Figure 23.
Figure 23: Call for Service, Points Missing
The example of 019 used in Figure 23
represents the number of missing points,
not a specific point number.
4.4 Low Transmitter Battery Conditions
When the transmitter reports low battery conditions
and replacement is necessary be sure to press reset
button on transmitter after replacing battery. Also, be
sure to test the transmitter for proper operation after
replacing battery.
4.5 Commercial Wireless Interface
Module Power Cycle Operation
In addition, when the commercial wireless interface
module is powered up, all transmitters report Normal
until their state is updated.
4.6 Frequently Asked Questions
What is the range of Inovonics Echostream Wireless
Transmitters?
Range for any wireless device depends on the
environment. In general, radio signals will be absorbed
into materials that contain moisture, such as concrete,
water, and earth. Radio signals will bounce off of metal
surfaces and penetrate fairly easily through drywall or
glass. In any case, the radio signals will lose some
power as they pass through or come in contact with
objects. For comparison purposes the only equitable
measurement is "true-line-of-sight". This is a condition
where there are absolutely no obstacles between the
transmitter's antenna and the receiver's antenna.
It is rare that an installation has a true-line-of-sight
condition so for a more definitive answer on range we
suggest you test the environment with an EN7016 Site
Survey Kit.
In a typical building environment our 900 MHz signal
propagates easily around the metal studs and concrete
floors. Customers regularly tell us that they are
impressed with the performance. If additional coverage
is needed we offer an EN5040-T High Power Repeater.
These repeaters support an unlimited number of
Inovonics Echostream wireless transmitters.
How can I increase the range?
You can use the EN5040-T repeater to extend the
range of any Inovonics Echostream wireless system.
What does the red decode LED/light mean?
This LED is located on the wireless receiver circuit
board. It is an indicator of the RF noise in the area.
Every time the light blinks the receiver is attempting to
decode a signal. This light shows that the unit is turned
on and working. It is listening to all of the radio energy
in the environment to determine if any signals are
coming in on the Inovonics Echostream protocol. If a
valid CW signal is received, the adjacent Valid LED
will illuminate.
