  1. Hi All, So i have the required parts now. I managed to get another 9930 keypad as a temporary measure so will put this in until i can upgrade to the newer keypad. One question i have is : Do i need to disconnect the 12v and 0v wires from inside the panel first or can i just remove the 4 wires going to the old keypad and connect straight into the new keypad without opening the panel box up? I suspect there might be an issue doing it this way (is that what you meant by shorting the cables). Thanks for your reply in advance....
  2. Thank you for all this advice...it great! Can i remove the 12v and 0v wires on the 'bus' connection inside the main box without disconnecting the main power? Also i note about not shorting the 12v/0v wires - how would that happen? Thanks again.
  3. Oh really? that sounds promising.... So can you suggest a step by step way of replacing it? My guess is : 1) Switch off mains power and disconnect battery 2) Enter tamper code (alarm box will continue to sound) 3) Open up keypad - I assume some wires will need disconnecting at this point? 4) remove old keypad 5) fix new keypad to the wall 6) rewire the removed connections back in? 7) reconnect battery and switch back power If the above is correct, are you able to talk me through the connections needing disconnected and then reconnected please? Thank you in advance
  4. Thank you Andy - are you able to talk me through the steps of swapping the old one for the new one at all? Just worries i think its easier than it actually is? Thanks datadiffusion - I know what you mean but at the moment it seems the easier option rather than having to rewire and fit a full new keypad...although the fob operation sounds really good - not sure i would know how to program them though...
  5. Hi all, Looking for a bit of advice please. Got a Scantronic 9751 with 9930 keypad. Keys have become poorly responsive and looks like needs the keypad changed over. I have manged to get hold of another new 9930 keypad. I have the engineeer and user reset codes. Is it as straightforward as taking off the front of the keypad and swapping it over for the new one? I know there is a tamper alarm as soon as the front of the keypad is taken off but the code disables this. Is the general advice to cut the power supply tot he alarm and disconnect the battery first although this means the bell box keep sounding. Will the settings remain known to the system despite swapping the keypad out (ie is the memory of the settings stored outwith the keypad box? Thanks in advance
