Thank-you Ano.
Curious why you use both a Quickbridge and an HAI 42A00-2?
I initially installed my Omni Pro II before the HAI 42A00 existed, so I increased the Omni Pro II to 48 wired zones, and dedicated 16 of these to wireless using 2 Quickbridges. They have always worked fine, but the one weakness they have was they could report a Supervision Error or Low Battery to the panel, but you had to actually look at the Quickbridge to see what zone was having the problem. Since I'm using CQC now, I wanted it to know which zone was causing a problem so I could use this info elsewhere.
Anyway, HAI released the 42A00 some time ago, I figured I'd replace my two Quickbridges with a 42A00-2 and then I would have some extra wired zones if I ever needed them. I installed the 42A00-2 but soon discovered a "flaw" with it concerning keyfobs.
The Quickbridge can learn up to 45 keyfobs into any zone, so one Quickbridge can support up to 45 keyfobs. In addition to that, the Quickbridge has a few more tricks up its sleeve. For example, you can learn the Lock & Unlock Buttons Pressed Together into zone 1. We use this for the panic function, press both the Lock and Unlock buttons together, and the panic function is activated. As far as I can tell, the 42A00-2 doesn't support this double key press.
In addition, while the 42A00-2 has up to 48 wireless zones, each button on each keyfob uses one zone. A four-button keyfob uses four zones. 5 four button keyfobs use 20 zones.
Since the Quickbridge can handle keyfobs so much better than the 42A00-2, I decided to keep one Quickbridge for keyfobs, and use the 42A00-2 for all the other supervised smoke alarms and door sensors I have. The sad part is, the 42A00-2 instructions don't even mention keyfobs, whereby the Quickbridge instructions dedicate about 70% of the text explaining all the different keyfob functions it has. Why the 42A00-2 doesn't have these keyfob features, I have no ideas.
So, if you are ONLY using keyfobs, you still might want to consider using a Quickbridge instead of a 42A00-2.
