You should be seeing an On and Bright to the address with a single button push.
Hold it longer. An On and a few Bright commands.
Sounds like you held the button long enough to go into the Panic Mode.
The KR15A is designed to send X10 RF commands to an SH10A Small Powerhorn. Through an X10 Transceiver.
If you send it an On and then Bright commands for a Ding and Dim for a Dong.

If you hold the button long enough.
It starts the panic mode. Sending the needed commands to trigger an SH10A to sound an alarm.
The only thing that I get is if I hold the button long enough all the sirens in my house go crazy loco.
There is
NO dings during a single button press. There is
NO dings during a press/hold.
Only sirens when I hold it until the light on the KR15 stays lit. And in other news. If I hold it long enough to set off the powerhorn, I get a very interesting look from the wife. Not sure if these are related however. More troubleshooting needed to determine.
