Other that pressing the test button on the front to check it has power, how do I get it to go off? I tried putting it near the exhaust but the alarm did not sound.
What make is it , was it cheap , i would get in touch with the shop you bought it from or get in touch with the makers of it and see what they say.
Start up your bus in the garage with the door shut. If that doesn't trip it nothing will. Remember not to breathe whilst applying this test.
We tried the exhaust test with 3 different units. Gave very strange readings in that they didn't go off. With my tailgate open and Mikes bus running behind it bumper to bumper in the workshop it did.
If you haven't got the Manual that came with the detector, Fire Angel do pdfs of all their instruction manuals....Google it and I think you will find all you need. I've still my paper copy and it goes through all the test routines.
Found instructions - they say incense burner or cigarette, I am not a hippy type or smoke so I may try the garage test
