First ever post on here..

Been in and around  the F&S installation  game for a few years now but have never come across this, maybe one of you guys could shine some light on it. 

New installation of a 264, Line 1 has 2 x C072's and 1 x P026, no RKP or other modules on the bus, everything is programmed and tested on this line. 

Line 2 has 5 x C072's and 2 x P026's, along with 1 CP037 RKP and MX4 Prox.

Rio's are addressed from 201 > 207, all devices on Rios 201 > 206 have been tested with no issues, RKP and Prox reader function as expected 

On to the issue, Rio 207 (Furthest away from main panel, power sourced from Rio 205, 23m distance, 680 resistor fitted and link removed in panel) 13.8 v @ Rio 207.

On carrying out a walk test on each zone individually, Z2073 a DT along with Z2077 a DC gave no response to the walk test. 

The other 6 zones had no issues. 

The zone resistances of Z2073/Z2077 via option 21, 1K ohms when closed, and when resistance rises to 1K9 (roughly) the panel still returns a closed message, all zones are set to default EOL. 

Replaced DT and DC, and tested cables from them @ the Rio, 1k closed, 1K9 Open (roughly) on each. Tested the cable from the detection end while connected to Rio, shows S/C on panel around 12 Ohms resistance. 

Swapped the Rio for another that's known to work and the same issue remained.. 

Honeywell may be getting a call when I am back @ site.. 

Your input would be appreciated..

What happens if you add another Rio on the end ? Programme it in 

 

 

Sounds like job for jw or gg or some dude in err can't remember rich? 

Haven't tried adding anything onto the existing bus line due to time restraints today  

Everything looks from the outside, comm's 100% with all Rio's on both lines.. Lines are run in belden. 

Just haven't come across something as weird as this. 

 

I am no Galaxy expert but have you done any tests on the bus?

I have known people to remove the termination to solve some issues.

Is there a ground loop?

Resite the RIO adjacent to the downstream one on a metre of cable?

are you sure the resistor values are default on the affected circuits.

if the panel is showin a 2k resistance but showing closed looks like programming to me

Panel and all Rio's are set to system default, 1K balanced/eol, Having already checked that. 

Zones 2071 > 2072, 2074 > 2076 and 2078 are all working as expected with exactly the same resistor setup. 

The 2 zones are also on separate locations.

Haven't looked @ the bus as of yet,  not had time.

Might give it a shot when back on site, worth a crack. 

Thanks..

ok

id leave the rio where it is and disconnect all the circuits at the rio end and link all circuits with a 1k resistor.

Then assuming all show 1k closed change each circuit to 2k one at a time.

What do you get then?

Is all detection cabling new?

New install.. 

Found out what the problem was, one of the jumpers on the RIO wasn't making a true connection, replaced both jumpers, power cycled and

Found out what the problem was, one of the jumpers Slave/EE on the RIO wasn't making a true connection, replaced both jumpers, power cycled and problem sorted. 

Really strange, haven't seen that happen before. 

Every day certainly is a school day. 

Thanks for the replies.. ?

I thought you had swapped the RIO?
