Common questions
What sensors can I connect to the GG-2?
Any gas sensor with an industry-standard 4-20 mA output, including the CTI sensor line. CTI notes it is not for temperature monitoring.
Can it power horn/strobes?
Yes. CTI states the GG-2 power supply can also drive external 24 VDC horn/strobes.
