The old alarm unit demised. The new one looks the same but behaves a little differently
It can only accept a 6 digit operation code. The old code was 5139 then #
New system Code is 513900 (00 added to old code)
Disarm uses 513900 then [padlock open icon button] on right . There is 45 seconds beeping time to disarm before alarm goes off.
To arm the unit use 513900 then [padlock locked icon]. Again 45 seconds beeping to get out before armed.
The buttons are quite particular as to how they register a keypress so make sure each keypress registers.
Any problems, I can disarm from home (this is new).
Good luck
Terry
