I also have other things to note:
- Despite instructions received directly from Bullnet, I was not able to set a timer for switching on / off the device with remote control. This works on the same unit (by pressing the "home" button the countdown starts, but not by pressing the remote control).
- There is no way to set the beep silent and very strong voice saying "system armed" or "system disarmed" - very annoying when you must not wake the others (I put a cushion on it to hide the noise!)
Otherwise, it installs all motion detectors and door easily with double-sided stickers. It's a little quibble duty whenever put his secret code and encode each detector and each remote, but once that is done, there is no problem. The alarm works perfectly and deserves more stars if it was a little more developed.
