Hi, I am brand new to security systems! Can anyone explain the difference between the Ademco 4219 the 4229 Zone Expanders? What are the Prograble Form C Relays for?? How do they work? I am planning new wired system and want to get the right components the first time! Thank You!

Hi All, This is my first post, great board you have here! :) Heres my situation, when I bought my house the alarm system was turned off and no codes given to me. Its a ademco vista 10se per the panel enclosure door. On the main circuit board at the top it says SA142GENC W51993 8164 On the PCB, theres a black metal piece that covers the main chip labeled VS10E n8576 N5850-95V2 and on the main chip a sticker that reads WA6764V10. I have found out what the installer code is, not sure if thats the same as the master code since I did the procedure to add a master code IC + 8 + 2 + new code and it doesn't give me the 3 beeps afterward? But I can arm and disarm the system using the installer code, only problem is the keypad is worn out and now the "1' button is dead so I need to replace it. While I'm at it I would like to add wireless glassbreak sensors for 4 different windows since I need to replace the keypad anyway.I'm not going to subscribe to a monitoring service, just use it locally and I'm looking for the best upgrade path for me an alarm novice. I do understand basic electronics, have a ohm meter, testlight,soldering iron etc.. The options I've found so far are the now discontinued 6128RF keypad, their are still some on ebay but I don't think I can program the new wireless sensors with this alone?? Theirs the 6150RF which replaces the 6128RF, in the description it says "Keys can be programmed at the panel, and enrolled locally". I dont know if that means wireless sensors are covered or what?? But it has the : 5881ENM 16-Zone Wireless Receiver 5800TM Status Transmitter So it will work w/the wireless sensors, I want to find out the best keypad to use that hopefully can just plug in and not have to be programmed from scratch for the current zones already setup by the previous owners. In regards to the wireless glassbreak sensors are the "5819 's Shock processor and transmitter" what I need for a glassbreak sensor on the windows? All my windows have a bar to keep them from opening so i'm just covering the ones on ground level for breakage. Thanks in advance for any help, this is a great website and I'm learning a lot! Sorry this is so long-winded! Mark.
