Elk relay clicking

[RobWalker]

I am hearing an occasional clicking noise from my M1 like a relay toggling (twice). It doesn't seem to have any fixed pattern, nor does it appear to be related to any rules I have defined (I believe I heard it before I defined any), no input zones are changing status, nothing ...

The only noticeable correlation is that it seems to cause ElkRP to lose the network connection it had to the M1 XEP. But the whole M1 isn't rebooting - at least there is no startup message spoken as at power on and there is nothing in the log.

Anyone have any ideas?

Can you measure the voltage input to the panel? Maybe it's low for some reason.

Do you have a relay board attached? I'm guessing no, but if you do, you can disconnect it and see if it continues. If the sound is coming from onboard, then check your phone connections, it could be the phone relay. You can just remove the green phone connector as a quick test.

Thanks for the suggestions. There's no relay board, and I'm not using the phone features at all (we don't have a land line installed so there is no way to call out).

I'll measure the input voltage when I get home tonight.

It is probably the telephone relay where the M1 is doing a telephone test of the incoming telephone line. It has to switch from the house phone power to the outside telephone line during the test.

Under Global programming on the M1 you can disable the Local Telephone Remote Control of the M1 by entering a value of "0" at G01. This will stop the telephone testing and the relay click when it tests. If you connect a telephone line, the clicking will also go away because the M1 will quit trying to power the inside telephones and checking for the outside telephone line restoral.

Thanks for the suggestion ... I went to change this setting and found it was already set to 0. Of course, I haven't heard the clicking at all this weekend.

For what its worth the incoming power reads 19VAC which seems a little high according to what is written on the board.

Make sure you do not have a telephone number definition defined also.

19VAC reading with a lightly loaded control is normal. Under max load it should read about 16VAC on the transformer input terminals.
