Ademco 5800RP Implementation

messages? If the wireless panel is close enough to a 58xx and 5800RP to
receive both the original message from the 58xx and the rebroadcast message
from the 5800RP, does the panel assume they are the same message due to
close proximity in time? And, if two or more 5800RP are used, how do they
avoid pinging back and forth? Do you suppose there is a brief window of
time where they do not rebroadcast messages? Finally, what if two 5800RP
units are within range of the same 58xx and attempt to rebroadcast the
message at almost the same instant? How does the panel receive messages
from two 5800RP units broadcasting at more or less the same time. In
summary, how do you suppose these issues are resolved?

It probably acts like any other 2 way radio repeater which ever
message gets there first is rebroadcast
and same with main receiver it Annunciates first contact but if 2
signals come in at same time you will hear chime twice in a row.
Either way the RP works very well where I have used it.

But what if two message arrive at almost the same time? Wouldn't the
collision cause interference?

Thanks, that's good to know.
I'm replacing a LYNX with a VISTA 20P/6160RF (I want to add relays). The
LYNX works flawlessly, but the 6160RF lacks the same range. The LYNX works
anywhere in the house, but no matter where I place the 6160RF, I can't get
full coverage of all sensors and keypads. Do you suppose a 5883H would have
worked better than the 6160RF?

I would shut down the RF portion of the 6160RF and go with the 5883ENH
instead. I have run across several problems with the 6160RF not working
right after a while.

I agree with Jim I would always rather have a signal straight thru
than thru a repeater

OK, I think may do that. I think that's a much better option than resorting
to a repeater if possible.
I reread the 6160RF manual and see that it recommends at least 10' between
the panel and the keypad transceiver. Given that the 5881 can be mounted
inside the panel (with antennas outside the can), I would not have guessed
that such a large distance would be required. I separated the 6160RF and
panel and I think I'm close to 100% coverage now. The separation made a
significant improvement in coverage. I may be able to use the 6160RF, but
if not, I'll disable the transceiver and add the 5883.
Thanks again for your assistance.

I have found that by mounting the receiver in the can with antenna
pointing out actually increases range of wireless as it gives you a
grounded back plane .
Rarely have i needed the repeater and even then signals hit most times
i was using it as a back up when high noise was in area.
I have transmitters inside the radio tower huts at WAVL which are 300'
from receiver and getting hit with 5000 watts of AM and they still
trigger every time the 5800 stuff properly installed is pretty good
stuff

That's good to know. How odd that the 6160RF requires separation from the
panel. I have not yet mounted the panel to the wall and I did a number of
tests with the panel and 6160RF in various locations around the house. If
the 6160RF is too close to the panel, range is poor and performance is
sporadic. If the separation was too small, it could not communicate with a
5828V in the next-next bedroom (two walls and 30').

I believe that you are experiencing the conflict between distance,
wave length and null points or consider the following:
Usually, putting the receiver at a high elevation, centrally located,
cures most transmission problems. However, large metal objects,
( kitchen appliances, automobiles, large mirrors, [especially old
mirrors], HVAC ducts, foiled insulation or wall paper, etc) can cause
bounce or deflection or reduction of signal and may require some trial
and error location of the receiver. In some cases, only two receivers
will suffice. If you don't want to mess around with the trial and
error, start out with two receivers or a repeater, depending upon the
mfg you're using.

Christopher there are ways in a wireless system to implement anti collision
scheme, hust take a look at AX25 protocol you will surely grab something,
and about repeating the same signal received once by the 58xx and 5800RP all
event in this type of wireless could maybe work with event id (could be a
mix of the event and the time of the event occured, time since last normal
report or such pattern). Me I would implement something like that, remember
that those systeme are bidirectional..so a panel can send a sync signal to
have a pattern that have a time stamp in events..
But that just speculation..
ax 25 info..
Christopher Glaeser
Yeah, seems reasonable.

Thanks.
