This project is to utilize a Particle.IO Core (Formally Spark.IO), a Cloud enabled IoT device, with signal from a STI Driveway alarm STI-34100 and utilizing its lamp controller port to give much greater capabilitity to the alarm system.
STI Output details
The accessory transistor output jack, where the optional Lamp Controller (STI-30104) plugs in,
will supply 75mA at 12V for three seconds. The output is a 3.5mm mono audio jack and is
polarity sensitive. This output can trigger the Lamp Controller or another low powered devices
such as a relay. It allows the output to interface with many home automation products.
Alternatively I can use an Opti-isolator to drop the volatage down. In the picture I have a 1 Channel ready to go
