Heat Detector Spacing Requirements

[@zohaibamjad4463]

if there is a hurdle so on what distance we should place our detector?

If the ceiling hight is continuously going down, will we multiple with different number? I mean in a shed the top of the shed is 25 feet hight but after 80 feet its turning out just 16 feet so is it necessary to reduce the multiple factor?

I have a question, there is beam ceiling with height of 5.5 m and the beam depth is 1.1m and distance between beams 1.6 m (this case is not as mentioned in the code so how to locate heat detector? Sorry another question related to integration between smoke and heat detector in one beam ceiling as my case above?

Great video so far. I have a question, There is a old fire alarm panel that installed at 1980, do you know what’s the code says about the heat detector type in the bathrooms at Motel? I would like to upgrade the system and the current heat detector is 195 inside the bathroom and then the sleeping area is 135 degree. Can I go with 135 instead of 195?

That should be determined based on ambient conditions in the space. I imagine a bathroom shouldn't get so hot that it needs a higher temp device, but you may want to double check that there isn't anything different happening in that room, like maybe a space heater that could cause false alarms. Some other possibilities is that maybe it was changed with the wrong part from a service tech that either didn't know better, or had the higher temp device with him. Again, the device installed should match whatever the ambient temperatures call for.

if I have a ceiling 90 by 90 with 28 feet high?

Good presentation! When you discuss spacing between detectors you show the clause that the minimum spacing between between detectors shall not be less than 0.4 x ceiling height. You then show a table which talks about multiples of listed ceiling heights and say that the value of 0.34 would not be ever applied. I think there are two different things, the first one being % of ceiling height the second being % of listed spacing. If you can kindly clarify.

Thank you for sharing.
