It is a Piezo Beeper/Sounder. I had a chance to look at a few different hardware revisions of the 2450 I/O Linc Modules. They use the same LNK354GN Switching Power Supply IC as the 2413 PLM and V2 Access Points. C7 was the part I found changed. Between hardware revisions. Hardware V1.0 0851: C3 6.8uf/250V C11 100uf/25V C8 10uf/16V C7 10uf/25V 25V rating was close to the 21VDC I measured on it. Hardware V1.8 1202: C3 6.8uf/250V C11 100uf/25V C8 10uf/16V C7 10uf/50V Mounted horizontally over PCB. As it was large to fit the boards hole spacing. Hardware V2.3 1430: C3 6.8uf/250V C11 100uf/25V C8 10uf/16V C7 220uf/50V Mounted horizontally over PCB. As it was large to fit the boards hole spacing. My thoughts are. In V1.8 C7 was changed to 10uf/50V for a better safety margin. In V2.3 C7 was changed to 220uf/50V to beef up the power supply. The original 1.0 had a very small filter capacitor and the output actually went down when the relay coil turned On. Use a capacitor for switching supplies.

There was an announcement about maintenance but it indicated 10/29/17. Maybe it got changed. https://forum.universal-devices.com/topic/22739-isy-portal-maintenance-10-29-2017/?hl=portal

You using On/Off relay type or dimmer type switches? Unless marked dimmable. CFL and LED bulbs should not be used on a dimmer.

I just tried the Start Linking method. It did not work for me. Kind of a round about way, but I have done it with a ControLinc. That is the most ornery Insteon device I have ever seen. If you have a new module is best . I added it to my ISY994i. Looked at its links. Manually linked the RemoteLinc2 to the module. Then looked at the modules links again. The mismatched link is the Remotelinc2 six digit Insteon ID.

I believe the Auto Discover needs the six digit Insteon ID. If it does not work. You may want to try the Start Linking method. Then put the RemoteLinc 2 into the programming mode. With the Set Button. If found. It will be added by its six digit Insteon ID.

Possible the connection between the thermostat and the adapter was getting poor. Disconnecting and reconnecting cleaned it up. Power cycling by removal and reinstall cleared up a glitched controller chip. Another thought is it maybe starting to fail. Though the FCC Database photos don't show any capacitors that typically fail.

2412S firmware v.63 is old and is a 417 Link Database model. The later ones where >2000 Link Database but most found above 800 Links started missing things. I don't have any exact data on it but it not cooperating with latest models would not surprise me. I also remembers some firmware versions being quirky. I would seriously think about a new PLM. The 2413S PLM also has a faster processor and memory. So it should speed up operations. The wall wart in my ISY994I kit is a 5 Volt 1 Amp.

The one in my ISY994i kit was a 5 volt one. As pointed out the voltage has a wide range. The 2412S supplied unregulated +12 volts to the ISY controller. That typically was closer to 20 volts.

The Smartenit EZIComm is their version of a PLM. Serial or USB along with the RS485 option. It is built on a main board they buy from Smartlabs and add a custom Daughter Board. Present ones are on a 2413 main board and specifications say it is Dual Band. I believe the earlier ones where on the 2412 main board. I would expect the Dual Band ones would have the same power supply issues as the 2413S/U and hardware V2 2443 Access Points. Never used one. I would think when used with an ISY controller. You could restore it just like a Smatthome 2412S or 2413S My Simplehomenet {before changing name to Smartenit} EZX10RF is built on a 2412 main board.

How old is the PLM? The 2413S PLM has a reputation to have a failed power supply. Usually over the two year old service time. Post the results from the tests Michel linked to.

You maybe thinking of the 2440 or 2440BK Original RemoteLinc. It has an All On and All Off button. They only worked with Insteon Modules linked to one of its buttons. Modules not linked to a button. Did not respond.

One thing to remember. The 2412S could power the ISY994i. The 2413S can not power it. If you have the wall wart from the ISY994i package. It will be fine. If not, you will need a power supply. The 2413S has a faster processor clock and memory. So you may also see improved performance.

In away that could be better. I have seen reports here that the Motion Sensor II is not supported in V 4.6.2. Though some have added them as the old model and got some basic functions. Without the new features it has.

Are you using the Insteon 28422-222 Motion Sensor II?

I was able to add mine using the special drop down choice in the Link management tab. Though it looked like what Michel indicated. Could not properly see any IR Links in it. Mine is a V1.A, 1444 reported .4A firmware. I have never seen Smarthome or developer Smartlabs have an official method to get firmware updated. They said we do not update firmware or provide the source code to do it yourself. With the 5 pin programming connector on the main board and a programmer. UDI may have a better idea. My feelings are maybe contract Customer Service.

You can't. The 2380 is the 600 Watt. Two Way X10 Switchlinc. No Insteon features in it. If you are interested. Here is the 2380 Manual link. http://cache-m2.smarthome.com/manuals/2380_web.pdf

IMHO. It is a cover where you sit down statement. That way if you used a dimmable LED and it didn't work correctly. They can say incandescent only you didn't follow instructions. As you have seen. Many of then are fine with an Insteon dimmer.

You said you updated to a ISY994i. Didn't it come with a wall wart as part of the standard package?

The 2412S PLM provides power to the ISY Controller. The 2413S does not provide power. So be sure you get a wall wart supply also. If you didn't have a optional wall wart supply. With the 2412S. The long capacitor fix thread here will not work on a 2412S. Completely different power supply design. 2412S has a linear power transformer design. The 2413S has a switching power supply. I can look up the capacitor data for the 2412S if you want it. The 2413S is Dual Band as pointed out. It also has a faster processor and memory. So it may give you added performance.

Yesterday I tried the standard drop down Add Module method and it failed. Today I used the Special Choice method in the Link Management drop down list and it did add properly. I did notice yesterday the Add Module way tried I2CS messaging. As the module did report it was a I2CS type. Though it failed. This morning with the special module method. It did add correctly but Event Viewer in level 3. Showed I2CS module found but reverted to I2 messaging. The firmware found was v.4A Although I was able to add 2 test nodes. The Device Link Table tests showed a mismatch with what the ISY994i indicated it should have. Complicated procedure to do. So I don't know if I missed something or the firmware was the issue.

Thanks for the update. Insteon times its communications to the AC Zero Crossing. I vaguely remember. The frequency had to be very close to 60 cycles for it to work correctly. The newer 50/60 cycle models I have no data on.

I have seen Date Code format changing between early and later modules. I have a failed V1.5 1122. Now repaired as a spare. Yours is 30th week of 2011. Mine is 22nd week of 2011. I have also seen a production code sticker on some. That confuses even more.

You will probably also see a hardware revision number on a white sticker. Like my latest is V2.3. The one Smarthome says fixed a problem they found. Thread on how to repair. http://forum.universal-devices.com/topic/13866-repair-of-2413s-plm-when-the-power-supply-fails/

How old is the 2413S? As pointed out they are known to have a failed power supply. After two years and a few months. One clue would be Link Database in the PLM empty or have few entries. Restore fixes for awhile. Not responding but a power cycle fixes it for awhile is another. As is a dim or out LED on the side. There is a thread here on the PLM issues. http://forum.universal-devices.com/topic/13866-repair-of-2413s-plm-when-the-power-supply-fails/

There is a small chance. That the inductive spike when it goes off. May effect the I/OLinc operation.
