D8125INV Power Cycle Operation
If the D8125INV is powered down and then back up, it may take up to a maximum of 5 minutes for all the transmitters
to report back to the D8125INV with their current status. On systems employing fewer transmitters, this time is reduced
proportionately.
to report back to the D8125INV with their current status. On systems employing fewer transmitters, this time is reduced
proportionately.
In addition, when the D8125INV is powered up, all transmitters report Normal until their state is updated.

Inovonics Frequently Asked Questions
This FAQ is reprinted with permission from Inovonics.
4.5.1
What's the range of Inovonics Wireless transmitters?
Range for any wireless device depends very heavily 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.

At this writing, there are 2 types of output power used on Inovonics Wireless transmitters.
1.
High Power. The line of sight range is 10,000 ft. Available only in the FA250 and FA570/575.
2.
Standard Power. The line of sight range is 2,500 ft. Available in all transmitters except the FA250.
The FA250 will program the same as the FA210W.
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 FA715 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
FA570/575 Intelligent Repeater. These repeaters support an unlimited number of Inovonics Wireless transmitters.

4.5.2
What is the range of the Inovonics Wireless repeater?
The repeater uses our High Power specification in its output. The re-transmit range is 10,000 ft. line of site.
The receive coverage area is dependent on the power output of the transmitters it repeats.
4.5.3
What does the red decode LED/ light mean?
This LED is located on the circuit board of Inovonics Wireless receivers. 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
Frequency Agile protocol. If a valid FA signal is received, the adjacent Valid LED will illuminate.

4.5.4
Does it matter what way I plug in the programming cable?
NO - As long as the 3 pins are inserted into the programming cable, polarity isn't important.
4.5.5
How can I get more range?
You can use Inovonics FA570/FA575 Repeaters to extend the range of any Inovonics Wireless system.
4.5.6
Why can't I program more than 1 transmitter per point?
Programming more than a single transmitter to a given point number defeats the ability of the Inovonics Wireless system
to supervise itself. This is a practice called "stacking points" and is discouraged in practice. Never stack points in a life-
safety or security application.

4.5.7
Are your transmitters weatherproof?
Our FA223S pendant transmitter is water-tight to a depth of 1 foot. In addition, we offer the ACC640 NEMA Enclosure
for outdoor environments. Many installers simply seal our transmitters in PVC pipe when used in outdoor
