In my opinion, I think System Sensor has the most high end products out there!

[@original8879]

Very good!

I have this unit and its beeping from last week. What could be possibly wrong with it? Installed 6 months ago.

[@NooDLES411911]

How do you do pressure differential for these? Im reading the newer ULCS536 and it says "Duct smoke detector pressure differential to be confirmed and recorded in the remarks column."

Nice install, but is there supposed to be tape on the sampling tubes?

[@FireAlert]

no, I put it there so that if the house is burning it won't go off and we will all die, Thanks for watching!

I'm probably gonna get a System Sensor D4120 duct detector, if I find one thats new at a low price on ebay.

[@123qatar7]

It's installed in supply or return duct ?

why does this video not have sound or explanation?

[@OftenAlwaysFresh]

Oh man, I'm working at a school and it has 2 of these in parallel but neither one has the reset button on them, do you know how to reset the tamper?

[@original8879]

Check the original manual or drawing… there has to be one! Sometimes it doesn’t appear like a button even.

[@vrryan6]

What was that button you were holding?

[@FireTech7]

That's the tamper switch that cuts power to the detector when the cover is removed
