Last week I updated the firmware for the Silent Knight panel to the latest version. This did not fix the issue of the Timer Test not making it through to Central Station. I went back last Friday and updated the firmware for the AES radio and the IntelliPro board in the AES. I then changed the dialer number that the AES is looking for from the recommended 55555 down to 555. This seems to have fixed the issue of the Timer Test not coming through. The rootfs-188.8.131.5208 is the latest firmware update for the AES radio and the Firmware_Update_Utility_6.0.17 .zip file is the firmware and update utility program for the Silent Knight 6000 series panels.
