GSM call alarm is a device that will call a destination number via Siemens or Ericsson GSM phone (19200 bps RS232). It has 1 sensor input and another input - state (stanje). If state input is = 0V than the device is "active" and it monitors the sensor input. The device is deactivated when state pin is connected to Vcc (+). Sensor input is triggered by 0V.
In project file for download, you will find a JPG image that describes how to program the number you whish to be called when alarm occures. I hope you will find some use for this device, as I did - for my car.
I build circuit again and it is working.The yellow diode is blinking every 15 s.I found siemens
S45 but when i connect the phone to the circuit, nothing happen, yellow diode still blinking.
What is the problem now???????????????
Thanks again. IP: n/a
Hi, is PIC16f84A 20/p DEAD.The circuit not respond, when i connect the power, nothing happen,
but if a touch the pin where is connect the oscillator i think is 12 pin all diodes are
flashing, and it doesn't work.
Thanks??????????????????Please IP: n/a
Hi i build the alarm but it was working for 3 days not in my car but, i connected to PC on 12
V, i wanted to test it. after 3 days the yellow light not blinking, i think is dead, why ?????
now if i touch the 11 pin on PIC with finger the yellow light is flashing constantly. I wonder
what is the problem?The PIC or crystal, HOW to check the PIC, because it is expensive here ?
Thanks a lot bye. IP: n/a

hi trax...how are ya? ive tried your simple pic 16f84 programmer, i build it and tried it in
icprog but it shows verify code error when i program it. can i ask if what hardware setting
will i use? or there is something to configure? i used JDM in the settings but it displays
error in the end. Thanx Trax IP: n/a
Every car alarm has one wire that is GND when alarm is armed, and it is VCC when alarm is not
armed. You will find that wire in your car-alarm and connect it with GSM Call Alarm
"ENABLE" input. IP: n/a
Hi me again ,i build the all circuit,but i still wait for pic,i cant find it in shops.That is
ok.But i have a question? If i put all sensors to 4 door if i close the door on car how to
activate the alarm, i mean to touch on/off wire to GND out of my car,funny a?I mean how to put
it in standby position,if i do that before open the door, when i open the door it will
ringing.I mean can i activate with ringing to mobile which is connected to GSM car alarm.I
found with sms but with ringing?
Thank you, and good IP: n/a
