I also look forward to your report on how it works.

The PC1832 Installation Manual shows two zones and a common. Like Z1 Com Z2; Z3 Com Z4 etc. Also shows all the commons are tied together on the PCB. Including Aux Power - and Keyboard - If the zones where wired with a 5600 Ohm End Of Line Resistor Detection. The Isolated EZIO Inputs may have triggered a Tamper or Zone Problems. Though I have no actual information on what would happen.

You may find that 90 Ohms you read was being influenced by the trickle voltage mentioned. If you measured it connected to the panel. If the sensor was powered and you then disconnect just the signal wires. What is the resistance of the motion sensors output?

The motion sensor may have a built in resistor so the panel can sense if there is a wiring problem. If the resistance is too low or high it may flag a problem zone on the panel. Do you have any model numbers for the panel and motion sensors? Not easy to find DSC data but I have helped someone with a ADT branded DSC PC1555 panel.

You are welcome. Avast and Zone Alarm are also known to have problems. You may want to do a search here as there maybe somethings you can change in Kaspersky AV to allow it to still work and the Administrative Console to function.

Are you running a firewall or anti virus? If so what are they?

40 failed? Where some of them the older ones with known tact switch problems? The ones where the paddles pushing would intermittently work. Those where given a 7 year warranty extension for just intermittent button operations.

If it is stuck On and even the local paddles will not turn it Off. The surge from the bulb burning out damaged the switch. Another clue is the bulb goes off with the Air Gap switch but is stuck On as soon as the Air Gap switch is closed again. Call Smarthomes Insteon Gold Support Line and explain the problem. They will probably replace the switch. I believe I have seen others reporting switch failures in the Smarthome Forums.

2477SA1 is listed for Indoor use. Maybe you could put it in a weather proof enclosure.

I believe it is still 5-30 volts DC 300ma. Mine came with a 5 volt 1 amp for future expansion. viewtopic.php?f=27&t=8647&hilit=Power+Supply

Any messages on the power lines {probably RF also if it is a Dual band PLM} during the PLM link database counting through the Administrative Console will give you a messed up count.

#1 915 MHz. Some models in the FCC Database are slightly higher or lower than 915 MHz. You can see internal photos, external photos and test results for the Insteon Dual Band Devices in the FCC Database. Grantee Code SBP. Product Code: If you leave it blank all models in the database will be found and you can pick the one you are interested in. Details Tab for device you picked https://fjallfoss.fcc.gov/oetcf/eas/rep ... Search.cfm

The MEM and ERR LEDs flashing is a network connection loss. You may first want to look at Tools, Diagnostics, PLM Info/Status. To see if your power cycle of the ISY99i lost connection to the PLM. If it says not connected. Power down the ISY99i and PLM. Then power up the PLM followed by the ISY99i. The ISY99i goes into a safe mode if the PLM is not detected and many features are not avilable for safety.

Many of the modules are detailed in the UDI wiki. On the main page is a section for optional modules. http://www.universal-devices.com/mwiki/ ... =Main_Page

Except for a few upgrades that use added hardware. Most added modules are firmware only. When you purchase the module. The added features are added to your unit remotely. The IR is slightly different as you have to physically add the IR hardware board to the unit and buy the add on. Purchase Modules function is in the Help Tab of the Administrative Console. Opens a web page where you can see the avilable ones and their cost. I have not seen a separate list of Module prices lately.

Andy. If you are switching to a ISY994i. You may want to first do the swap from the ISY99i with the original PLM. Then when everything is OK. http://www.universal-devices.com/mwiki/ ... _.28PLM.29

#1 yes that is how I did mine. Restore ISY using the last backup. I had to then point the nightly Query Program to My Lighting. #2 I also sent the uuid for both my ISY99i and new ISY994i to UDI and they transfered my modules to the new uuid. The ISY994iZ-IR-Pro is avilable from Smarthome. http://www.smarthome.com/12235/ISY994iZ ... ler/p.aspx I have not seen an add on hardware module on the UDI site to add it separately yet.

With the older 2412S providing power. It was an unregulated 12 volts that was closer to 17 volts depending on the load.

My ISY994i seems to process things like checking links faster but it maybe just my perception of what is happening. The ISY994i may use more power. I have not seen any requirements posted but mine came with a 5 volt 1 amp supply. Maybe a cushion for added accessories at a later date.

Don't forget an external power supply. The old 2412S supplied power to the ISY99i. The replacement Dual Band 2413S does not supply power to the iSY99i and you use the external power connector on the ISY99i to power it.

My original I/OLinc displays 20 and I can set the time and it sticks. Next time it again shows 20 but the 50 I set was still active. My I2CS Beta model shows 0 and I can set it. Next time it again shows 0 but the time did stick. Hoping it is just my beta device as I could not have momentary C work at all.

Installed fine in my ISY994i

3.2.5 was just released. So probably going for the latest would be best.

Not going to work with out a SD card. Mine has a 1GB one in it.

Make sure that 3.2.4 is displayed in the UI and Firmware lines of the Help Tab About Choice. Do you have any Dual Band Devices or a passive phase coupler in your setup to bridge the homes split phase power?
