Regardless of when you arm you system, beams are more susceptible to
falsing than other type of sensors.  Critters outside an aviary can be a
big problem.  Rather than an alarm hooked to a beam, I recommend a light
hooked to a sensor for outside to discourage stray animals.  One can
also install an outer perimeter fence with a low electrical charge to
discourage strays.  Works for me!
