Elk relay clicks on/off at random intervals

I just wondered if anyone could explain this. I have my new M1 Gold set up in the office while I program and test (play) it, and keep hearing it turn a relay on and off by the sound of it. At random times. The same noise it makes after I disconnect Elk RP I'd say.
 
There's no telephone line connected to it, just a databus and some keypads and an elk wireless. And the XEP.
 
Just wondering if this is a sign of something not set up right or an issue. Or just the Elk doing some self-testing.

Do you have a backup battery connected?

Yes I do.

My vote is for the dialer/line seize relay.

And as usual I'd say DELInstallations is right. I hooked up my IPDatatel CBAT and it seems to be happy now. Thanks, just wanted to be sure.

Mine does the same thing.

I am also having the same problem. I do not have a phone connected or configured. Factory suggested I reset M1 to factory default and see if it still clicks. If it doesn't, start reconfiguring M1 slowly and see if clicking starts again and that step would be what is causing the problem. I have nto had time to do this.
