Galaxy Dimension compatibility with SSR Detectors

[Quintas]

Hi Tech6. I hope everything is OK with you.

I´ve already done tons of different tests.

I think I can conclude that the problem is not RF interference.

Changing the response time, either to Fast (20ms) or Slow (1000ms) makes no difference. The problem is more frequent with external RIOs, but, I think, changing resp.time makes no difference with these ext. RIOs: they are V1.00 and the manual says that function 6=Resp.Time in 52-Program Zones is only applicable to zones on RIO rev 1.2 and above. Anyway I kept this function = System in all zones and changed Parameter 27=CCT Debounce to either 20 or 1000 ms, for testing. It made no difference, even with onboard zones.

I tested with only one detector connected either to an external RIO or an onboard RIO, screen cable wired to earth, the problem persists. And its not that one detector problem, since it happens with different detectors, from different brands.

Twice, there was a detector in an external RIO with high resistances for several consecutive days. I covered the dectector with a paper and the problem went away for as many days (14) as it was covered and came back after I uncovered it. I did this test because I noticed that, in rooms in the house where we rarely go to, their detectors rarely have high resistances, and the opposite happens. From here, I should think that the problem has something to do with the relays opening and closing. But it also happens with smoke detectors, once with a door contact and once with the tamper loop to sirens.

If I close the zone with a 1K resistor inside the detector, bypassing its relay, the problem seems to go away, so. I think, this also excludes RF interference.

Spare zones closed with 1K resistor on the panel side never had the problem, except, perhaps, once. These zones normally have resistances between 1000-1020 Ohm, and only once one spare zone reached 1042 Ohm.

It seems like the panel is not reading or calculating the resistances correctly, but it also happens (and more frequently) with external RIOs; I don´t know if the resistances are calculated by the external RIOs or by the main panel with the data from the RIOs.

 

I've runned out of ideas and spent so much time with this that I'm willing to buy a new system. Either stick with Honeywell (but I would have to buy a new PCB plus two RIO expanders) or go for Texecom (Premier Elite 48 ?) or Pyronix (EURO 76 ?). Do you know which one would be easier for a DIY?

Thanks and I wish you a great 2025.

The fact it stops when bypassed with a resistor removes the cable or rio being the issue. 

It does point to the sensors but as it's a cross multiple ones I'd say not. 

What's the power supply like?

Hi.

I have random high resistances in most zones of a Honeywell Galaxy Dimension. I would like to replace my panel with a new one, but I've been told these panels are incompatible with detectors that have solid state relays (and I have several of these).

Can anyone confirm this information?

Thanks.

Ir really looks like it's a detector thing. That's why I was told there might be an incompatibility of these panels with SSR detectors. But I have both detectors with and without SSR and it doesn't seem to be any difference.

What puzzles me is that smoke detectors also have the problem (and their relays should be closed all the time), and once a door contact and the tamper loop also had high resistance (don't know the resistance of tamper loop, but I had a fault warning, years ago, that never happened again).

Power supply, battery charging, etc seem to be ok, according to diagnosis option. Anyway, I replaced the backup battery with a new one, the same with all the fuses. I can also exclude a  power supply issue, because external RIOs used to be supplied by an external PSU and had the same issue with their detectors. They are now supplied by the panel, for testing purposes.

After dozens of tests I've already done, I was thinking of a panel issue, but can't be sure. Between buying a new panel and two new RIOs, latest versions, I' m more inclined to go to another brand, if they can do everything this panel does, independent groups, etc.

fully independant groups nothing beats the galaxy.

Everyone has their preferences but the galaxy (when working lol) is a solid panel. 

The most flexable panel i use is the Acre / vandbilt spc. Plus the ones with built in ethernet allow programming via web interface, firmware upgrades etc.

But obviously you will need all new peripherals if you chnage brand.

I'm aware of that. Thanks anyway.

If I stick to the Galaxy, I'll have to buy a new panel. Do you know what is the latest firmware I should look for?

 

[Secware_Tech6]

Which galaxy are you looking at? 

[Quintas]

I have a GD 96. I suppose it could also be a GD 48.

The Dimension panels can be upgraded no need to replace it, however for the High Resistance issue a engineer would have to visit the site and do some troubleshooting.

Thanks guys for all your support. I'll have to decide what do do.
