Hi all,
I have a DSC alarm system which will set a specific port (PGM1) to ground if the alarm
goes off, power (6V ( i think) available from a COM port)
Today, I got a GSM unit with pin1 (actually 8 pins) which can be set either to NO, NC or EOL. Now, I
want to trigger the the GSM unit to send a SMS if the DSC alarm system goes off.
- Both systems have their own DC power from AC.
- I need the simplest solution to fire off a SMS when the PGM1 port is going to ground.
- Since I'm quite a newbie when it comes to electronics, I need some verification from you skilled guys! :*
My assumption is that I can use a transistor by setting DSC COM port to base, AUX on GSM alarm to emitter and
both DSC ground and GSM pin1 to collector. If there is a current between DSC COM and PGM1, there will be
current between GSM AUX and pin1. Is this correct?
hints for getting this properly setup will be VERY appreciated! XD
Thanks!
Daniel
