I am a student myself these days. and your instructions give a fast catching up with the formal books for the Exam ! I learn alot , thanks. Fire alarm is a big thing in the electric business .
i know he's no longer around to answer. but maybe others know.. if I wanted to change the duct detector, what wires would I short together so as to keep the FACP happy and not go into alarm? can I just disconnect the power and the zone wire?
Joe when testing differential pressure between the sampling tubes with a digital manometer... Do you take an average reading or a peak reading? I've seen some fluctuations from pass to fail.
+Robert Cortez The international building code requires them to be on the one side and the international mechanical code requires them to be on the other. I don't remember which is which. Some towns adopt IBC, some adopt IMC. I've seen them both ways, and I've also seen many buildings that have detectors on both the supply and the return.
That changes state when the detector activates, same as the regular alarm relay. It just allows for another circuit to be controlled by the detector in addition to the alarm panel.
11 years since posted and still helps students like me. Thanks
The best ever video series I found for fire alarm...amazing and outstanding job..Thanks Joe !
Very simple way to explain. Thank you so much.❤
Really helped me. Most videos on these are more HVAC related, and not so much fire panel related. Thank you.
amazing explanation. Helping people.. Keep it up..

Been there thanks you mr jeo
And also a relay with a mmf
Can the duct detector be installed on the supply or does it have to be on the return?

Wish youd hook up the switch to it now
What causes the Aux Alarm relay to change state?
That changes state when the detector activates, same as the regular alarm relay. It just allows for another circuit to be controlled by the detector in addition to the alarm panel.
Why is my duct detector keep getting full of water??
Probably condensation
