Re: Vsita 15P programming question

Thats not exactly the situation I presented. I should have added the word
IF...what trouble are  you going to detect IF a window/door is opened in a
loop with multiple switches and the EOLR at the proper position (in a closed
loop alarm circuit - switch opens in alarm) . My point is you're not
supervising too much in this case.

| The EOLR is not intended to detect an open window or door.  It is intended
| to detect a short on the loop.  That is the purpose.  Whether you decide
to
| use it or not is your decision.  Most techs either don't use them on burg
| loops at all or place them in the panel where they serve no useful
purpose.
| For the sake of clarity, I'm not saying that you ought to use them or that
| you shouldn't.  I'm only saying what they are supposed to do and that most
| folks don't do it.  There's no judgment involved.  It's the decision of
the
| technician or DIYer whether to use them.

| The purpose is to supervise the integrity of the circuit, not the sensors

of
| the person doing the job.
