I have a home alarm system as well. Same gadgets and all. Smoke, glass, door and window, motion, etc. However- When you open the door and the alarm is on, theres a chime but NOT an alarm until 30 seconds. This time is allowed for the homeowner to disarm the alarm if they are coming home or forget. This 30 seconds an intruder can get pretty far into a home (or in my case, my apartment). So, my Glock is c1 on my nightstand, and my mossy is ready to go right under my bed.
