Thx. So for the Home and 250 connectors, there's just a difference in being tested for the 900Mhz or not. I presume this is also valid for the 500 as the specs are almost identical to 250 and Home. Or is it more like this: all connectors are tested in the factory, the ones that have best test results are marked 500, the others 250 and the last batch 125. Anyone some inside info? As I'm completing the last part of the installation where the wall sockets have already Home or 250 mounted on the Net cable, is there any added value to apply 500 connectors to the patch panel side? Would you leave the 250 in the wall sockets and install Home on at the patch panel side, or is it better to pair them (250 with 250 on same cable, meaning I'll have to remount connectors)? Your insights are very much appreciated! Rgds, Christoph

Hi, (non native speaker, so I'll post in English) I have a LK IHC Net installed. Part is done with Home connectors and part with 250 connectors. The electrician reassured me that the 250s were the same as the Home connectors. And indeed they look identical except for the color coding (change to standards from early Home connectors) and the engraving on the metal enclosure (250 iso Home). Install instructions were identical. Both were bought in Belgium via local distributor. So should I understand this as just an export branding name change? Or is there a difference between both? Thanks for your feedback. Christoph

Yes, it works again! 12V on pins 3 and 5!How did I do this? Not sure ... but here's what I did:1) Powering off power supply (so only drawing current from the battery) leaving only the 12V LED green on the module. No difference in values measured, so 24V on 3 & 4 and 3.5V on 3 & 5.2) Powering on again. No difference measured.3) Decoupling all contacts from pins 3 & 5. (I know, should have done this sooner ... instead I decoupled everything from 3 & 4 before in an attempt to lower the current drawn) 4) Rewiring all contacts to pins 3 & 5. (It is actually only one wire from the backup module itself to a connector from where different wires go to the seperate devices)5) And hey! 12V between pins 3 & 5.So two options here that can explain:1) internal Alarm Backup trouble ...2) wire badly connected ... Thx for the program to calculate the current drawn. I will nevertheless still verify.The alarm PIRs attached do indeed have a dedicated NC contact. So it's isolated (I presume) from the controlling part of the setup. Happy regards,Christoph

Hi,Thx for the quick feedback.@lars-jacobsen:Pins 6 and 7 indeed supply 12V and are only connected to the battery. @claus82:I will verify the power draw as there are quite a number of elements connected. The Pirs indeed stopped functioning after the tamper circuit was closed (so brought under tension 24V, but this circuit is not drawing a lot of current doesn't it?). I'll post my feedback tomorrow.If indeed the Backup module is recharging the battery, it would be OK to connect the Pirs to pins 6 and 7. Even if the 0V is different between pins 6 and 3, as long as I wire the relevant pair of pins, the Pirs are fed with 12V. Could any of you confirm this (in theory :-) )?Please also not that the 12V LED on the front of the module is giving a steady green ...Kind regards,Christoph

Hi all,Following this forum from Belgium thx to google translate ;-) , so please allow me to ask a question in English.I've got a working IHC installation, including the alarm setup. That alarm setup contains 3 Alarm Pirs, a keypad etc. Everything worked fine. Recently I finally closed the tamper circuit ('status') (that for various reasons wasn't yet fully looped). After that, the Pirs stopped responding. Analysing the problem, I discovered that the Alarm Backup module only feeds 3.5V iso 12V between pins 3 (0V) and 5 (12V). Before I had never measured the Voltage, but they operated as should, so I assume 12V was present.Measuring the other pins on the Alarm Backup give the correct Voltage back.1) Anybody an idea?2) Could I alternatively connect the Pirs to pins 6 and 7 (so directly to the battery)?Kind regards,Christoph
