Customer Question

I have a 30 year old Ademco Advantage key-pad. Some keys on the key-pad have lost their ability to properly make contact with the key-pad. It seems that the black contact
material on the keys have lost their ability to complete the circuit when they make contact with the board. Can I purchase a new key-pad for this model or if not is there a substitute
panel that would be compatable with the system?
Thank you

Hi Glenn,

First you could try cleaning the circuit board with electronic contact cleaner. That may help the keypad to make better contact with the circuit board.

If that does not work then we can look at replacements, however given the age of the system it may be difficult to obtain a compatible substitute. Could you attach a photo of the keypad and let me know the model number if cleaning the circuit board does not help?

Hi Pete,
I will give your suggestion a try. Can I use isopropyl alcohol instead, as I do not have any electronic cleaner on hand? I have removed the circuit board and with the little used # ***** pressed this key onto the circuit board and it activates the contacts.
Is there any substance with which I can re-impregnate the tips of the plastic keys on the key pad?

Hi Pete
There are several sets of numbers on the circuit board.
On the soldered (sodered?) side:
C Pittway 1993 N6539 REV B
On the component side:
SA6127 B W9996
On stuck on piece of paper S1632
Underwriters Laboratories Issue No. B-8980
I hope this is of some help.

Hi Glenn,

Yes, you can use IPA instead. Let me know if cleaning works?

Could you also attach a photo of the control pad?
