![]() The two major ICs I can see on the product image is a *339 comparator, and a 117-5G LDO regulator - a pack of 50 LM339's is around $5 ($11 using PPP), and a pack of 5 117-5G's are around $2.5($5.80 using PPP). I can pick-up a NodeMCU board for around $7 locally, and other components are generally dirt cheap from local electronic suppliers. We were able to download and find the NX-12 manual and have read that we need the master code to change or add any user codes to the system. We were only given 2 alarm remote controls, no manual and no master code details. For that amount I could buy the best "big-brand" alarm system, and have it professionally installed and have money left over! The zone light (s) that is illuminated corresponds to the system. We recently purchased a property which has the Networx NX-12 system with the DAS Alarm Keypad. Using the current exchange rate and purchasing power parity data ( ), $239 locally is about the same as $ 565 in the US. The problem is that I live in South Africa, and excluding shipping costs, $239 for the 18 zone kit (Which is what I need) is a crazy amount of money in local terms. ![]() I am a person who is very very interested in using the new Konnected Interface kit to turn my dumb/old alarm into something a bit more modern and smart (Unfortunately cannot just replace the old alarm with a full Konnected kit because insurance companies here are strict about which alarm panels you can use).
