DYI: multiple window sensors on same zone?
Eric Moesle
just want to be sure it can be done.
Purchased a home with an old Ademco 4110 system already present. Someone on
this forum previously showed me how to reset and reprogram the system, since
I didn't have the previous passwords and codes.
I now want to add a few more window sensors, simple surface magnetic
contacts.
Can I just wire these together into one zone on the panel? Would like to
put all master bedroom windows on same zone, all kitchen windows on same
zone, without having to buy a new system for extra zones. Don't want to use
internal motions as an alternative to window sensors since I wnat protection
for my family at night with the ability to move around.
Also, should I wire them each into the zone at the panel, or is it OK to
wire them together distantly, with only one set of wires leading to the
panel?
Thanks much.

series on the same zone. Likewise you can wire several normally open
(circuit closes on alarm) sensors in parallel on the same circuit. However,
neither of these practices is the *preferred* method. Whenever possible, it
is best to wire your alarm system with one sensor per zone. That way if
there's ever a problem you can go directly to the component needing service.
Also, less sensors on a zone means less spliced connections and that in turn
means less total resistance in the loop. Greater resistance, in the
extreme, can result in false alarms. This isn't a major problem but
anything you do to keep your loops cleaner will accrue to your benefit.
If you do decide to add multiple sensors to a zone, just make sure you make
the splice accessible in case you ever need to service it later. Splicing
at the panel can take more time now but it can also prove to be a time saver
later.

individually for future troubleshooting. Also a motion detector inside is
advisable in case an intruder breaks through the perimeter of your home
without activating the system. You can of course program the motion
detector as an interior device that will not be armed when you have your
system armed in the stay (at home) mode.

I read in some tech literature that 10 ohms per motion detector needed to be
calculated into any zone where more than one device is used.

often imperfect, adding an Ohm or two each. Cable runs add resistance as
well. The less you have on a given zone the better.

scenario you described. I would make all splices in the panel so they are
accessible to you should you need to trouble-shoot in the future.
You can add motion detectors to that panel. I arm my Ademco system in the
STAY or Instant mode at night. The motion detectors and all interior zone
types are ignored in this mode.
If you need help programming or adding to your system we specialize in DIT'ers
and particularly Ademco brand equipment.
Stop by http://www.alarmdoctor.com and we will be glad to help or send an e-
mail to in...@alarmdoctor.com.
Good luck.

Don't waste zones separating windows for some catastrophic event. It only
takes a few minutes to trace trouble on a multi-contact zone. It is no big
deal.

The resistance on a contact should be close to zero. On motions, many
manufacturers add a resistor in series with the relay contact. Ive
seen them at 10 and also at 15 ohms.

determined by several things. The length and gauge of the wired loop are
directly proportional to resistance -- longer run or higher gauge ~ greater
resistance. Also, each splice may add an Ohm or two, depending on how well
you do your connections. A proper soldered connection is usually best, but
crimps are often used effectively.
For the sake of any newbies who may be reading this, please don't ever just
twist the bare leads together and tape them. Such connections will almost
certainly degrade over time.

panel in series for close ckts. make them neat labeling them so when
you have to troubleshoot them you know what you are looking at. try not
to put more then 4 or 5 max on one zone.

accommodate the extra opennings, windows and doors.
The purpose of these alarm systems are often generalized and not really
completely understood by the user/owner of the system,
If , God forbid. a break in occurs while home and in the early hours of the
morning. People have approximinately 8 seconds to react. The source of this
came from afbaa statistics on home invasions here in Az. In eight seconds, you
need to be protected and know the point of entry, As a service tech, I have
seen many sad scenarios where people were victimized because they weren't
capable of reacting to the threat due to lack of information. The fact is that
98 percent of alarms or false however when they are real and your at home,
usually loss of life is a reap possibility. I know, I have a friend that was
killed in a home invasion. He didnt have security. Good luck.
