Hi all,

I have a really nice RAB motion sensor/halogen flood light set up, and
I want to run a wire from the output side (which turns on the floods)
into my house so that it notifies me with a small light bulb in my
living room.

That part is fine, but I want to have a momentary buzzer or chime come
on when it is first tripped. How can I do this?

Thanks!

Why not just purchase something like this
http://www.smarthome.com/7312/Drivew...MA-3000/p.aspx ?

Or this http://www.x10.com/products/sc546a_sp_tm_ps42.html

Or this http://www.gadgetshack.com/reporter.html

You get the idea. There are many other types of sensors you can use without
goiong through the hassle of reqiring the floodlights.

I have something just like that (Dakota Alert) which is great. I just
want to also do the flood lights. (Its a hobby thing)

Check the voltage at the light bulb and replace with a buzzer of same
voltage? WW

That would work if he wanted a buzzer to ring the entire time the light is
on - probably 2-3 minutes minimum if it is like most motion lights.

He's probably going to need a relay of some sort that will trip when the 110
current is detected and cause a momentary trip-switch to toggle to ring the
buzzer or bell. The relay will have to remain tripped until the 110 is
off (when the motion light goes out), recycling the trip-switch for the next
time the motion light comes on.

That won't do the momentary thing that he wants. I'm still scratching my
head trying to come up with a simple way to do that, short of cooking up
some kind of one-shot circuit.

Hmm, the momentary aspect slipped right by me. Let's see, the indoor
light bulb quickly heats a bimetallic switch, thereby cutting power to
the buzzer.

I was going to suggest to you, Dakota Alert. Their unit has a set of
contacts in the receiver, that are time adjustable and can be connected to a
piezo buzzer. You can build one yourself, but it's a tad complex. You need
an adjustable time relay, that's adjustable to fractions of seconds. It must
have a 120 volt coil and a normally open switch contact. You need a signal
device,( buzzer), and a power supply of the same voltage. Wire the relay so
it closes switch circuit for fraction of a second whenever lights comes on
sending low voltage to buzzer through switch circuit

They make time delay relays.

This is the cheapest solution I know of ($29):

http://www.smarthome.com/7279/Delay-Timer-Relay/p.aspx

The Elk timer relays are pretty handy, just mount it inside a steel J
box with some nylon standoffs and 6-32 machine screws and nuts.

but for the count-down off feature you described the above the ELK-960
above would be it, it even has a "pulse mode" to flash the inside
light based on continuous current detection in another circuit, or
just do a timed off of the inside bulb.

Thanks - Would work if I had the lower voltage, but I'm stuck with
110V output from the motion sensor (don't particularly want to add a
transformer).- Hide quoted text -

- Show quoted text -

Any of these will operate at 50/60 Hz and sense the current by just
looping the insulated hot lead through the coil one time. When
current flows in the house wire a small voltage will be induced in the
coil and be enough to trigger the Elk relay. These current sensing
coils typically cost around 1 to 4 dollars retail:

I use this same setup to turn on a humidifier whenever the furnace fan
turns on (with no physical connection being made to the fan circuit
other than the current sensor). Similar priciple as an AC clamp amp-
meter.

There are more manufacturers than this place try Global Spec to find a
web seller.

Wire a slow-blow fuse into the line to the buzzer. With enough trial
and error you'll find one that lasts only as long as you want the
buzzer to sound before it blows.

Hang on, I know what you're going to say next: "I want something that
will work more than once."

All you need to build now is a "Automatic Fuse Replacement" mechanism
that will eject the old fuse from its holder and insert a new one.

Wait - I got a better idea: - seriously, this might work:

Get a mercury switch and make a mount attached to a 110 motor that
only moves a fraction of a rotation when energized. When the light
comes on, the mercury switch will close the circuit to the buzzer/bell
but the motor will also come on and tilt the switch, turning off the
buzzer. The motor will stay energized (and the switch will remain
open) until the light goes out at which time it will return to it's
original position and arm the mercury switch.

For some reason this reminds me of the 3-strike relay we had in a 30KV
transmitter power supply I used to work on. If the xmtr shorted to
ground (which it had a tendency to do) it would trip a motorized
breaker and the 3-strike relay would set its contacts to the one-
strike position. The breaker motor would reset the main breaker and if
nothing happened within 30 secs, a small motor would reset the relay.
If the xmtr arced again within 30 secs, the contacts would move to a
second-strike position and let the big motor would reset the main
breaker one more time. If there were no more arcs within the original
30 seconds, the relay would reset itself to the original position and
hum merrily along. However, if 3 arcs happened within 30 seconds, the
relay contacts would go into the third-strike position and kill power
to the breaker motor so it couldn't reset the breaker. At that point
the xmtr was dead until we visited the machine and figured why it was
arcing.

It was a pretty neat electro-mechanical device that prevented down-
time due to the occasional arc, but prevented major damage if there
was a serious problem with the xmtr.

Here's what I did. I don't know if it's legal but it works quite
well.

Take a feed off of the wire going to the light socket. A simple
western union connection works well. Bring the wire back through the
lights housing back into the box and then into the house. Mine is
done to be inside a closet to give me some room. In there power a
Square D "One Shot" timer relay. The timing is variable with a knob
on top. The power comes on and energizes the relay and it stays on
for the time set on the relay. Then it shuts off the controlled
circuit until the power goes off (and comes back on) on circuit that
powers the relay. I ran my doorbell circuit through it so if anyone
walks up my driveway, it rings my doorbell.

I also put on two switches. One for the power so I can shut it all
down and one on the bell circuit so I can shut that down and leave the
light working.

The relay should be available any any electrical supply store. I
tried to figure out how to do it other ways and didn't have any luck
until I threw myself on the mercy of the guy at the electrical supply
house who said "I have just what you need...."

Install a doorbell transformer which will be powered by the 110
current from the motion sensor when it activates. No doorbell button
is used. Low voltage to light, bell or whistle in the house.
Transformer can mount close to sensor.

Like so many others, you missed the "momentary" part of the O.P.'s

Yeah, but like someone pointed out, many standard doorbell circuits
*are* one-shot. The buzzer type are continuous as long as you hold the
button, but the ding-dong type only go once even if you keep the button
pushed.

(lighting) loads. I replaced it with one rated for motors as well as
lighting.

I dunno. But designers of consumer products these days aren't known for
overengineering, so running it with a relay might be safest.
