DIY Cell dialer for shop alarm

[JRP]

My shop has a loud alarm system, but no phone wires. Today I adapted a prepaid cell phone such that it will dial my cell number if the alarm is triggered. Had to open the case and solder tiny wires, but it looks like it will work. A 12v relay wired to the alarm horn signal will signal the cell phone to call me. AT&T GO Phone has a $2 per day plan, you only pay for days used. I think if I test two times per month the cell line charge will be $4 per month.

Would it interest others to have a phone call if their shop is burgled?

There are also kits from Velleman that allow you to turn things on/off using cell phones remotely.

Great idea. How did you get the phone to dial your number? Did you punch in your number and then the alarm just triggers the "send/call" switch on the keypad?

In my cell phone I entered the alarm phone number as SHOP ALARM. in the alarm phone I set up my cell phone number in speed dial list, I chose number 8. If I hold down the 8 button it dials my cell number, and my cell says SHOP ALARM. Next I removed the number keypad from the alarm phone and cut out the number 8, exposing the gold pads the button contacts. To these tiny pads I soldered two wire and applied silicone glue to retain the wires. The wires go to Normally open relay contacts. When the alarm sounds it energizes the relay coil, Which close the NO contacts and the alarm phone speed dials my cell phone.

Nice idea! I am going to have to make sure I get a signal out in the barn before I try this.

I don't know anything about this company other than a house that I looked at to buy a few months ago had this system installed.

Along the same lines although shorter distance, instant and free, I built a bunch of game radios for hog hunting. The use digital voice recorders and IR motion sensors.

JRP,
Great Idea.
I have wireless driveway alert alarms on my entry doors from HF, $13.99 when on sale, good to 200+ ft they say. One of those set up inside the outbuilding would let you know in the house and hooked up to your cell phone dialer would call you anyplace. Remember not to lock the cat in the garage though.

I bought two of those on the same channel. I can set one for the driveway and one for the shop. My problem is with Opposum's and cats prowling at night setting the receiver off at 2am The one on my driveway I first took a picture of the tree I was going to put it on so I could camoe it and blackout the red led alert. I forgot and left it on today while I was cutting grass/leaves and was driving the dog nuts inside. :laughing:

I actually used the HF driveway alert motion sensor in the wood shed to "Bing-bong" me in the house when that racoon was getting into the dog food bin. Very effective.

Mine are set above the doors with motion detector lights, at a downward angle to detect motion only out to about 25 ft. We get a few cats, coons etc at night but they generally don't turn the lights on. Inside a building though unless you've got really big rats, you shouldn't have many false alarms and hooked up to JRP's phone dialer would let you know somethings up, wherever you're at. If you already have a phone line in the shop, there are several motion detector phone dialers for land lines available from about $20.

They are old radios from Huntsville prision that a friend gave me once most of the batteries died. There is an external connection for a handheld mic that has a jumper wire in it so the radio is always keyed up but with no power.

The IR motion sensor is a radioshack brand, for hog hunting I use the "pet lense" one of 5 lenses that came with it. The pet lense is designed to not set your house alarm off if you have a dog or cat but will trigger with humans. It works best because coons, rabbits and such don't call you out for nothing.

When the IR sensor does trigger it throws a double pole relay on the right hand circut bord that powers up the radio and the (radio shack) digital voice recorder, playing back and transmitting a prerecorded message. The only thing that is powered up all the time is the sensor that only draws 20mA so it can go weeks without needing to be charged.
