I've got an OmniPro II and most of my sensors are hardwired, but I have a few that are on my 42A00-2 GE/Interlogix wireless interface. I am finding that door/window sensors (2 different models tested so far) do not reliably catch fast events. If I open and close a door really quickly (too fast to get through it, but enough to get it open a few inches before closing again), many times the OmniPro will not register a zone trip, and even if it does manage to catch the zone trip, it almost never registers the zone restore. Unless I open the door and leave it open for a couple of seconds before closing it again, the zone trip/restore sequence isn't reliable. My application isn't actually a door, and it needs to be able to catch any opening of the contact (even if it's very brief), and then reliably send the restore when it re-closes.
Is this problem specific to the OmniPro wireless implementation of the GE/Interlogix system, or perhaps the type of sensor that's enrolled? Both sensors I've tested are supervised and send restores.
I also have a Linear DXSR system and at least with the wristband sensors (designed to be a panic button for personal safety) it seems to see even very short keypresses (if they're long enough to light up the LED on the wristband sensor, the system reliably sees both the trip and restore events).
I'd be interested in finding out if there are specific 319.5MHz wireless sensors that guarantee catching even very brief contact open/close events. I would think any security application would want to be assured of reporting *all* open and close events, even if they are very short, so I'm surprised by what I'm seeing so far.
