Afternoon Report
The “AC Loss” issue with our new alarm panel seems to be resolved, at least for now. After reprogramming the last few zones in the system, I unplugged the system and let it run on battery for several minutes. Then, I swapped out the old Ademco 4300 X-10 transformer, replacing it with the transformer that…

This and that
I had hoped to take a bike ride this morning, but ended up sleeping until almost 9:00. It was probably just as well, as it’s very hot and humid today, and would have been a rather sweaty ride. The reason for my oversleeping was that we got a call around midnight from our alarm monitoring…

Broken stuff
The abnormally-high temperature reading on my pool’s SWG that I noticed 10 days ago is back. This morning, it was reading 94°F when the actual water temperature was 80°F. The reading was consistently about 14-15° too high every time I checked today, all the way up until 7:00 or so, when I went out to…

More on Ademco Keyfobs

Saturday’s Hijinks
Another fun Saturday around the house… First up: The security system. I finally got around to relocating the wireless receiver to try to get better performance out of our new keyfobs. At the same time, I installed the status transmitter module so the keyfobs can receive status information. So far, things look good. the status…

Alarm Oddity
So, I’ve got the wireless keys programmed into the alarm. Everything seems to work. The only “wild card” here is the range of the things, because the receiver is mounted a little farther away from the garage than I’d like. If the range turns out to be a problem, I’d expect all of the buttons…

Wireless Alarm Keys Demystified
I successfully programmed an Ademco wireless keyfob transmitter today, and figured I’d document the process.. My panel is a Vista-20P and the transmitter is a 5804BD. Program an RF house ID into the panel. The house ID needs to be a number between 0 and 31. On the Vista-20P, this is done in location *24:…

Upgrading the security system
Four years ago, I installed a full-perimeter hardwired security system in our house. This probably ranks as the single largest DIY project I’ve ever undertaken. All told, it took me about four months, working alone, and splitting the time with my day job as well as household chores and other projects. Would I do it…
