Idea for Cheap Alarm System

I'd like to have a simple alarm.  It could be as basic as a motion
detector that sets off a loud siren.  I think that would scare off the
majority of intruders.  We come in through the garage, so I would
just  throw the circuit breaker to turn it off.  If anyone knows a
product like this, I'd love to hear about it.

Then I started thinking about something a little more elaborate.  What
if you had a cell phone attached to the motion detector that could be
set to dial a number if it were set off?  For example, it could dial
911 and play a recorded message saying the house address and there was
a burglary in process.  Or it could dial my cell phone, and then I
could decide if I wanted to dial 911.  A Virgin Mobile cell phone
works out under $6 a month, much cheaper than a monitoring contract.

Consumer Reports had an extensive article exactly on this subject a
month or two ago. You might want to check out the review online or at
your public library.

For many years before cell phones I used a system that would call
my pager and transmit a code telling me what was happening.  It
works very well.

    Some stores sell a battery operated device that attaches to a window
and emits a flashing red light. I keep one on my dash board.

I used to have a Radio Shack pendant dialer that would dial whatever
succession of phone numbers you wanted, play a message, and open
up a live microphone link inside the house to the phone line.

IIRC, it cost about $70 ten years ago. Being intended for the elderly,
it was activated by a pendant worn around the neck. It could easily
be adapted to do what you're thinking of doing. Mine worked fine.

The good part about this solution is that there are no additional
monthly charges, assuming you already have a phone.

I think those systems that are designed for the elderly should also have
some mechanism to detect movement and alarm if there is no movement
for a specified time between particular nominated times, so that if the
individual does die or is unconscious, the system will alarm then too.

Obviously the time between detected movements is different at
night and day and in the bedroom and the rest of the house etc.

The ELK-M1G home automation system can do all that.

The last place my Dad lived (independent/assisted living) had a switch
he had to hit each day.  It was a pull chain thing on the wall in the
bedroom.

If "on the cheap" is the whole theme of this thread, I can imagine a
simple timer circuit (a one shot with a duration of say 30-36 hours).
It's "reset" by the person each day (like my dad and the pull chain),
but if the timer goes off, the alarm is triggered.  There probably needs
to be a simple disable, in the event that the person will be gone for a
couple days.

Altronix makes a Tempo2 (replaces the TT1) 2-stage timer.
It could be rigged to trigger a voice/pager dialer such as
Paravox 710.  If the timer gets no signal for 24 hours (or
whatever duration seems appropriate) the dialer starts calling
4 different numbers, repeating until someone responds.

That isnt going to alarm as quickly, and suffers from
the problem that its easy to forget to pull the chain.

Even a warning that the chain hasnt been pulled isnt going to alarm as quickly.

And it needs a pre alarm warning that the alarm is about to go off too.

Thing is, a "daily status" is probably good for most folks that are
still independent.  If not, maybe they shouldn't be independent!

The think I know from my dad, and other people in that age group, is
that it's got to be really simple.  Pre-warning buzzers and flashing
lights will just get them PO'd.  Let's say "grandpa" forgot to "push the
button"..  Worst case, is the kids get a call, and he gets a phone call.
  Thing is, with a simple timer, it doesn't need to be a "pull chain",
but could be a trigger from a motion sensor in the bathroom.  If they
don't take a pee in 6-24 hours, there's a problem!

Re: Idea for Cheap Alarm System

It makes more sense to integrate all this stuff into the
alarm most choose to have, and do a lot more than just
daily status with everyone, particularly those who choose
to live alone when its so cheap to add to an alarm.

I've never been convinced about that, it actually needs to be quite intelligent
instead.

Cant agree with that at all. They are likely to get much more pissed
off about the alarm going off and triggering some intervention when
they just forget to pull the chain at the right time of day.

And thats why a more intelligent system that works automatically on
movement is much better than something simple too, you dont even
need to hit the stupid chain daily, or need to pull it when it warns either.

Quoted text here. Click to load it

Much better to pull the chain when it warns than to
have to field that call when its just been forgotten.

Sure, and that is what I proposed originally.



Re: Idea for Cheap Alarm System

I think he means that using it has to be simple.  On
that I agree.

Quoted text here. Click to load it

IME the gentleman is correct.  A buzzer or flashing
light isn't a problem as long as it's loud enough to
be heard but not so loud that it startles.  Also, a
phone call to check and make sure he's alright can
be a welcome event to someone who lives alone.

I had elderly customers whose alarms we used to
monitor when I owned an alarm company.  Once
in a while we'd get a "fail to test" signal at the
monitoring station and I'd call to check on them.
Elderly people living alone can feel isolated and a
phone call, even from an "agency", can be a nice
thing.

I think there are folks for whom a manual action
such as pushing an "I'm OK" button or pulling a
chain next to the bed when they rise can be best.
For others an automated system may be more
appropriate.  We shouldn't assume that one
solution is best for all clients.

Quoted text here. Click to load it

Not necessarily.  During the call he might say, "Yes,
I'm here but I'm feeling ill."  The central station op
could then send help or notify a family member.

You can design an elder care system to check for
motion, respond to pendant panic transmitters, etc.
Sensors can be attached to the medicine cabinet
refrigerator door, etc., to make sure the client is up
and about, eating regularly and taking his meds on
schedule.

There's even a sensor you can place on the toilet
seat cover to sense when it's opened or closed.
The detector, originally intended to sense glass
breakage, is very appropriately named a "Wiz".  :)

The problem is that the OP (as another poster
reminded me earlier) asked for an inexpensive
system.

That isnt clear at all, particularly with his claim
about it not being desirable to have a pre alarm
warning but to wear the false alarms instead.

And while the chain system is simple, its really too
primitive. A completely automatic system based on
movement detection and a panic button that the
individual carrys at all times is much more useful.

Then it makes no sense to have a system which
requires the individual to pull the chain once a day.

Quoted text here. Click to load it

Sure, but there is no point in the daily chain pull for those.

Sure, but thats just as true of his keep it simple claim too.

Quoted text here. Click to load it



Using that line, there is no point in the chain system at all.

They'd be better with a daily phone call instead.

Its not necessarily just 'elder care' either, it makes a lot
of sense to have some mechanism like this for all those
who live alone, integrated into the alarm system.

Gets messy tho deciding when to alarm food consumption wise.

It doesnt necessarily add much at all to the cost of a decent
alarm system. Its essentially extra logic rather than extra
components with most stuff except the carried panic button.
And that is pretty essential to get assistance as quickly as
possible after a fall or just not being able to get out of bed
or the chair etc.

The main problem is that we could never get our geriatric to wear it.
He appeared to decide that it was too much of an admission of how
geriatric he had become, although he did get a cellphone on his own
initiative which he carried when out on his walks for exercise. I'd love
to why one was acceptable and the other wasnt, but it can be quite
hard to work that stuff out once they are getting rather nutty. Some
of them can be quite remarkably nutty.

You could have something triggered by a toilet flush, speaking of
pulling a chain.
Or maybe something that senses any kind of water flow through the
water meter.

Go to a bookstore, pick up one of the "Chicken Dance" birthday cards.
Tie the little tab to the window, glue the card on the frame.

Burglar opens window.  Da da dadda da da dat da da dadda da da dat and
so forth.  Burglar either runs away screaming or starts to dance.

There are already auto-dialers available, and you could use one of those
converters to use a regular phone on a cell line.

There are much cheaper options than Virgin Mobile as well.

That said, monitoring contracts don't have to cost $20-30/month. See
"http://www.alarmrelay.com /" There may be others that are even cheaper.
