GSM call alarm je uređaj koji za zvanje odredišnog broja koristi Siemens ili Ericsson GSM telefon (19200 bauds RS232) i ima 1 senzorski ulaz i još jedan ulaz - stanje. Ukoliko je stanje = 0V tada je uređaj "aktivan" i prati stanje senzorskog ulaza. Uređaj se "deaktivira" otpajanjem on/off (stanje) ulaza sa mase (0V) ili spajanjem na + pol napajanja. Senzorski ulaz takođe reaguje na 0V.
In .rar file you will find JPG file that contains a description how to program the telephone number which this device will call upon alarm condition.

When you put ON/OFF pin to GND, LED will blink fast for about 15sec. After that, it will blink
slow - meaning it is ready to detect SENS input. This will happen only after the phone is
properly initialized. You will now that it is initialized when yellow LED is always ON.
Everything takes time, so when you properly connect everything leave it for 3 minutes to
initialize. I have also uploaded flowchart in the original RAR file.

Use the one in "gsm_call_alarm". That one is tested and works great. If you are
having problems, check you crystal, maybe it is not working. If you can't get the device
working, try connecting TX and RX the other way around (It should be connected like this: ALARM
RX with GSM TX, ALARM TX with GSM RX, ALARM GND with GSM GND).

Hi trax, it's me again... which PCB layout will i use? the one in folder
"gsm_call_alarm" or the one in "gsm_call_alarm_new_ploc"... because i tried
the one in "gsm_call_alarm" but the led does not light up...thanx trax

Ok Thanks but i check every wire connection pins 100 of times i do not know where is the
problem.
But without connected phone should alarm work? i mean if i touch on/off or sensor to GND,
because the alarm not respond again, the yellow diode is continuing to blinking?.Maybe it does
not work with siemens S45?.
Tanks again bye.
