Strange, you never have to move a little or push twice+ ?

I think that you don't know what you talk about, the transmitter
frequencies are dislike.
A little study on radio techniques will help.

Hope you are right.

Just for the sake:
TEST with a small transmitter the reliability of your wireless alarm
system if:
- You like to confirm that a transmitter can muzzle the receiver
  and fail your entire detection system?
- You like to find-out if your system is really equipped with some
  kind of RFI detection circuit (like some pretend) and how long
  it takes to warn you (intruder <-versus-> warning delay)?

Well, purchase for a few boxes an authority certified RF transmitter
"operating on" your wireless alarm frequency

For all frequency types of wireless alarm systems:
