You can try Defaulting Just the Voice but I’m not hopeful this is going to correct this issue. From the M1KP2 keypad:
- Press the ELK key, screen should display 1-View/Control Automation Fncts
- Press the 9 key, screen should display 9-Installation Programming (0)
- Press the Right Arrow key at which point you should be prompted “Auth Required Enter Valid PIN” — Factory Default is 172839 or check Globals G29-G42 (Special) for “Local programming Code”
- Screen should display 01-Bus Module Enrollment
- Type 07, screen should display 07-Globals System Definitions
- Press the Right Arrow key, screen should display G01: =…..,
- Type 45, screen should display G45:DefaultCtl
- Press the Right Arrow Key and type 94
- Once complete exit from keypad programming and retest
Worst case the Board could be sent back to ELK for evaluation which would be subject to the Out Of Warranty Inspection Fee
