Veritas R8 PIR problem

[diy-newby]

Hi guys

We have a Veritas R8 alarm system. This morning we noticed that walking into
the kitchen did not activate the part alarm unset procedure. I performed a
walk test and both the kitchen and the living room PIR are not working.

The red light in the PIR still works, it is just not activating the walk
test procedure. Are PIR's self powered with an internal battery or do they
take power from the main alarm panel? The reason I ask is I have put quite a
few chipboard screws in the upstairs chipboard floor to cure loose /
squeaking boards, and am now thinking worst case scenario that some how a
screw has pierced a cable. But if the PIR takes power from the panel this
hopefully cannot be the case as the red light in the PIR still comes on upon
detection.

Can PIR's fail but the red light still activate?
Could this be a problem with the main alarm panel? Is there any other tests
which I could carry out to narrow down the problem?

TIA

If your PIR's are blinking "red" when you're walking in front of them,
chances are they are in fact hard-wired to the control panel. That
having been said, there are many reasons why your panel won't register
the PIR's. If they are programmed as "auto home/away", some panels
(like the DSC products sold in Canada) won't change state (show an
"open") when you walk in front of them. The best way to "walk test"
your PIR's is to ARM the system in the "away" mode (your panel may
require you to open the delay or exit door to do this). Wait for the
exit delay to expire and then walk in front of the sensor. If the siren
sounds, your PIR's are OK.

Worse case scenario could mean that one of your screws has penetrated
the four conductor wire to the PIR and shorted the two zone wires out.
Hopefully that hasn't happened.

Could you explain what this means; "...not activate the part alarm unset
procedure."?

He's speaking *English*, you American buffoon. You'd have to be
Canadian to understand him from this side of the Atlantic.

When in part set, activating the kitchen PIR starts a countdown procedure
where the code needs inputting in a certain amount of time before the alarm
sounds.

Hell of a price to pay, just to understand him.

Just for that, we're going to cut back on the power we're sending you.

I am guessing from your post, the living room and kitchen PIR's are close to
each other, even possibly on same cable, and I expect you have caught a
cable when re-securing the floor boards.

The Veritas R8 does not have resistors to alert you to this type of fault,
the detectors work on a normally closed circuit. When the detector light
comes on a small relay opens the circuit causing the alarm to activate. This
is not happening because you have created another closed (short) circuit
with the screw.

ah an interior delay zone...yuck.

We send power to California. We send beans to England.
