You may want to plug the module into the same outlet as the PLM. It could be possible you have a new signal sucker or power line noise maker. That is effecting the X10 signal to the chime module. The power line receiver in the chime module may have gone bad and it would still ding-dong on powering up, Try rotating the House and Unit Code wheels to clean them. We have seen some modules with age. Get intermittent and actually be on a different address than the wheels say they are set to.

As pointed out. We have seen brand new modules with test links not removed before being sold. Both the ISY controller and PLM have a maximum link database size. PRO adds a larger link size to the ISY controller and the 2413S PLM is ~1000 links.

Yes since the ZWave Security was added for the 500 series boards and is not for the 300 series ZWave boards. I take it you saw the 300 series 5.0.16C thread where it can be found. https://forum.universal-devices.com/topic/27669-5016c-isy994-last-version-to-support-z-wave-300-series/

Little more information. In the Scene I have it set to Siren Trigger Home, Duration 6 seconds, Delay Immediate and Chime Mode.

I am using that module in a scene and you may find three places to set parameters. The listing in the Administrative Console did not set what I wanted. In its listing in the scene list where I added it. It also did not seem to set what I wanted. When I highlighted the scene name it self in the Administrative Console. I was able to get it working the way I wanted it to work. One thing that may not be too well known. That module and the earlier Alert Module where the ones Smartlabs did not provide proper or any data on how it was to be handled. So it was reverse engineered by the folks at UDI and possibly may not function exactly as the manual says it should work.

Can't say about the 2477S but I know my 2635-222R On/Off Module was a refurbished 2635-222 and had a 30 day DOA exchange warranty from the now gone Smarthome.

From what I have seen. In my ISY994i. Restore Modem (PLM) does a software reset command of the attached PLM. Then writes the links into it and changes the old PLM 6 digit ID to the new 6 digit ID in all the modules.

The EMI SH21115AS is a 2 pole relay and the EZ SH1115A is a one pole relay. Though both pins for each function are tied together inside the original relay. The rating maybe the same as both. As the pin for each function are tied together on the board. So with the EZ SH21115AS both internal relays contact sets are in parallel.

Thank you for the link. I will give it a look.

I found some information on the relay you mentioned. It was a Goodsky product and as you mentioned 1/2 the power rating as the EZ. I have not seen a specification sheet on it yet but will keep looking.

The relay is a Goodsky EZ-SH-1115A. I have seen a few Ebay listing selling the relay but didn't check the status too closely. Some where used removed and tested. https://www.goodsky.com.tw/en/relays/general-purpose-relay/67-ez-relay

Yes that is the 120VAC coil relay used in the V1 2456S3 units. Near the Red output wire on the board. You will see the two open capacitor mounting pads. In Version 1.3 they where removed because they sometimes shorted and kept the load on. I have had a few of the larger 470uF/35V caps fail. In mine it pulsed on and off at about a one second cycle. Replacement fixed the cycling. If it is clicking I would think stillwater's though on a stuck contact maybe what is happening. Here is some information on the module. It is an Icon but the differences are no pass through outlet on the front and a green or amber LED. https://efundies.com/guides/. The what is inside an Icon module pages show the information. The partial schematic of an Icon Module shows the small P160J coupler and how it turns the 120VAC relay on and off. Yes the +5 volt logic voltage is connected directly to the 120VAC Line input. All the voltages are set with electronics referencing to the Neutral.

You could also measure the resistance between the narrower input pin and the narrower output jack. When unplugged. It should be a fairly high resistance. I measured around 250,000 Ohms in a version 1 and 330,000 Ohms in a version 4. If it is very low that would also show it has a welded contact.

It would be best to reset all the modules. If not it can lead to thing like missing or half links still in the modules.

You may want to look at the model and revision number. If it is a 2456S3 or 2856S3 Icon there are two major revisions. The original revision 1 models used a GOODSKY EZ-SH-1115A 120VAC coil relay and was in a white colored case. It did has a set of capacitors across the contacts to protect them but they where cut out at V1.3 on the 2456S3 and V1.4 on the 2856S3 Icon . Since they could short and keep the load on but they would smoke and you would have seen the smoke. The 24VDC coil relay is in the revision 4 models. They also have a snubber network across the relay contacts but I have not seen any reports of them shorting. Removing the 2.7 OHM R2 would disconnect it. Though it would also probably overheat if the capacitors failed. Both revision 1 and 4 have a local control sensing feature. That could be triggered by some inductive loads but if it just recently started that may not be an issue. You would probably hear the relay double click in the case.

The ISY994i has a large voltage input specification. 5 volts to 30 volts, 2mm barrel + center pin; older manual said minimum 300mA I would just be sure the polarity is correct + to center pin and correct barrel size to fit the jack. My first ones where 5 volts 500mA or 1 Amp. I have had a few over the years go bad. I see the presently sold ones are 12 volts 1 Amp. When mine went bad. The ISY994i was semi stable until I tried a reboot. It would start up and when the LED's started it shut down and started the whole sequence again.

As pointed out. The early models with Insteon support. Used a 2441V Insteon adapter into the Venstar T1700,T1800 and T1900 thermostat. http://cache-m2.smarthome.com/manuals/2441V.pdf. The later ones sold by Smarthome had Insteon signaling installed and had a Insteon style part number. 2441T Thermostat, 27232-232 or 2441ZTH External Insteon thermostat. I also have not seen a Wi-Fi modules for that line of modules. There are some for the more modern models available. I did see a Venstar wireless external temperature module available for that line of thermostats.

Venstar made an ACC0436 kit to allow folks with a simple two wire heat only setup. To use one of their programmable units that need a constant power feed. It was a 24VAC 200mA wall wart and a 24VAC coiled relay. So the unit could get power and isolate control for the two wire controls.

It stays with the module and its unique UUID. I have the A10/X10, Networking Modules on my main ISY994i. May spare ISY99i shows none of the extra module added.

The EZX10RF is built on a 2412 base PLM board with their custom daughter board. It acts like an all address X10 receiver and can map up to 20 X10 address to a Insteon Address Scene I believe. If you have the $9.00 module. It will show up in the Administrative Consoles. Help, About Tab. Should show up as an A10/X10 For INSTEON (21060). You should also see in the Add A New Device Tab. Entrees for an A10/X10 address. A10 was an enhanced protocol built on the X10 signaling.

That link is the PLM Pro by the now gone Smartlabs. It had a universal power supply 100VAC to 240VAC. 50, 60 cycles. Back plate was separate so it could be changed to match the local electric outlets. Faster memory and link database increased from ~1000 links to ~4000 links. Looked similar to the case size used on the 2457D2 LampLinc. Serial, USB and Ethernet versions where in the FCC data.

It only has three wires in it. RS232 Receive, RS232 Send and a signal common wire. The remaining connections on the PLM serial connector. Are TTL send, TTL receive and if the older 2412S unregulated +12 volts. Should not normally be connected to anything.

I too would suspect the power supply. There are many posts here with failing power supply. I have had a few myself. UDI presently sells a 12 Volt supply as the ISY994i has a fairly wide power specification.

I found my rough sketch of a 2430 supply area. The C2 470uF/35V is the 30 volt main supply and the 30V Zener diode is across the cap. The black mark on the bottom is probably that diode getting warm. I have seen this before. It is used for the power line transmitters power. The C4 100uF/16V is in the +5 volt logic supply used by the electronics.
