How to install a duct smoke detector housing my way
Quick video of me, installing a duct smoke sensor or smoke detector housing on ductwork. Sometimes the engineer can specify where these will be located on the duct and sometimes the local fire department gets to choose how many and where they want these on the duct. in my case the engineer wanted one on the return and the supply and here I’m installing one on the supply run. my scope of work is to just install the housing, either the Electrician or the controls contractor installs the rest.

I use your video to help my students understand the concept of a duct detector. Thank You

How do you install an autocall A4098-9755 By Autocall More specifically I am wondering how to install this in existing Duct work Supply and returns? Specifically, I am wondering if you extend their airflow tubes through the opposite sides? As you did with the model in your video. Also, I noticed that you only extended one airflow tube through the width of the duct work, the one with the holes but not the other...Why?

Hi sorry for the late response hopefully you were able to get an answer for this if this was urgent. To answer your questions, first off I have not installed that particular brand but they are all pretty similar. I always recommend installing any equipment per manufacturer’s instructions. There are two tubes. A test tube and an exhaust tube. The test tube should always be before the exhaust tube and holes should be facing against the airflow so air can go in the tube with the holes. The small pipe that comes with the equipment is the exhaust tube so the air that goes in the device can be exhausted out. Some brands say the tube should go through and some say you can stop two inches before the duct. It depends on the length of the test tube, if it’s too long it can break from the housing. So the smaller one doesn’t need to be extended because it’s just an exhaust tube. The point of this device is to get a test sample of the air to go inside the sealed enclosure which has a smoke sensor and then the air gets exhausted out by another tube being the smaller one. There’s no pumps involved so it’s important to install the tubes correctly.
