Point response is correct at the 
D8125INV, but incorrect at the 
control panel (for example, RF 
point is in trouble when it should 
be faulted, etc.). 

Point programming at control 
panel is incorrect. 

Make sure point programming at 
control panel is correct, especially 
the Point Response Type. 
Remember that regardless of 
transmitter type or configuration 
of an external circuit, the 
D8125INV will always report a 
fault to the control panel as a short, 
and a tamper as an open. In most 
cases, a point response type that 
gives trouble on open is desired. 

RF points change state 
unexpectedly, with no actual state 
change at transmitter 

Two or more transmitters are 
programmed as the same RF point 
number. 

Transmitters send RF point status 
(fault/tamper/normal) at status 
change and at 1 min. or 5 min. 
check-in intervals.  If two duplicate 
points are in different states, the RF 
point state at the D8125INV may 
keep changing as the check-in 
transmissions from each 
transmitter are received.  If 
duplicate RF points are in the same 
state, RF point state at the 
D8125INV will stay the same. 

 

There is another, nearby 
D8125INV system with 
transmitters, programmed with the 
same System ID. 

The system ID is shipped at a 
random value of 000-255. 
D8125INV systems that are within 
RF range of each other must have 
different System ID's, to avoid 
interaction of the systems.  That's 
why it's a good idea to check for 
duplicate System ID's if two 
D8125INVs are used.  Remember 
that if the System ID is changed, all 
transmitters in that D8125INV 
system will have to be 
reprogrammed as new.   

 

in RF Diagnostics 

Received signal level for that point 
is low. 

A second FA400/receiver can be 
added to a D8125INV and 
mounted in a different location to 
increase range An Inovonics 
FA570/575 high-power repeater 
may be used to increase range to a 
greater degree. 

 

in RF Diagnostics 

D8125INV has not received 
enough recent transmissions from 
that RF point to give an 'OK' or 
'BAD' signal indication; Several 
transmissions are required.  The 
signal indication will start out as '?' 
after power up, after programming 
an RF point, or after an RF point 
has gone missing. 

Cause several transmissions to 
update signal level.  About 4 alarms 
or tampers and 4 restorals spaced 5 
seconds apart will cause enough 
transmissions to get an accurate 
signal indication.  Without 
activations, it will take about a 
half-hour to get signal strength 
readings if transmitter Check-In 
time is set to 1 minute.  It will take 
about 2 hours if Check-In time is 
set to 5 minutes.
