Be aware that a WIRELESS alarm system CAN BE DISTURBED EASILY (even the most recent and modern ones). This can happen ACCIDENTALLY (you, newborns) or VOLUNTARY (intruders) with a low power Radio Frequency (RF) external source operating on the wireless system radio frequency.
== Is that exceptional??? == I read in a Electronic magazine recently:
-> HOW TO BUILD a RF link on the alarm system frequency with a transmitter of 400mW (sensors have only 10mW) made standard by AUREL (operating range +/- 10 km = 30.000 ft)
Due to the presence of an external RF source, the wireless alarm system receiver is overwhelmed (muzzled) and this INHIBIT ALL ALARM SIGNAL DETECTION emanating from the sensors.
The most annoying is that YOU WILL NOT KNOW IT. The system doesn't detect it (it seems that some systems do after a long time (min. 1 Hr to 12 Hrs) when the RF source interference persist during that time, unfortunately its not defined for that purpose nor proven to detect it and unsupported by manufacturers, its originated only by "low level electrician pro's imagination").

That easy!
