I'm going to phone Optex tomorrow and get the final word on this
problem. ( Although I have come to the conclusion that I am going to
have to install a real alarm system.  I posted this part previously to
ABLE1.)

If I get a bummer answer from Optex that disallows what I'm thinking of
doing, I'm going to do another simple Rube Goldberg idea that just
might deter the predators when we are home from advancing in further.
I'm going to have a wireless controlled switch set up to feed power to
a siren. I have such switches already doing other jobs around the hose.
If the Optex system alarms, I'll just press the keypad of the wireless
remote switch and have the siren go off. Why wait until they come
further into the house and have a gunfight if they are armed?  If the
alarm doesn't scare them, I'm adequately armed plus I have another
really great defensive weapon - my cell phone.  Being in a small town,
the police are literally only a minute or two away.

When we are not home, we have counted on the fact of our having 4 large
mutts who are not overly friendly to any passersby.  Any jerks who
might have been casing places I'm sure have taken note of this fact.
The mutts are outside for many hours during the day. Their presence
cannot be missed. However, I have read of two instances where some
bastards pepper sprayed the poor dog(s) in a home.  So, I'm being
rather forced into using a real comprehensive alarm system.  We've had
to move four times in the past decades because of the garbage flowing
into this country.  We're getting to old for this.  We have enough
"domestic bred" shit in this country, we hardly need to import more via
Barry Soetoro's determined effort at destroying present day America - a
'present day America' which has made him a millionaire.

Go figure.
