The sensor has a test mode and one uses a can of spray.
It appears that I would not really need to connect this to the security panel, since the sensors have their own internal sounding/ alert. As long as they are connected to a battery backed up power source.
And they would need to be looped so that if one goes into trouble, they both sound an alarm (if not connected to a panel)
Chasing Ernie's post count, one useless post at a time.
