- In this video, we will be talking about Heat alarms and the differences between heat and smoke alarms. We will also answer where you should install heat alarms, why you would use them, and the temperature they will sound.
Thanks for watching!

Hi, im studying building services engineering and would like to know would you put point heat detectors in all plant rooms or just boiler rooms
Hi Frankos, For this one you would be best contacting our tech support team to get your answer. support@psaproducts.com.au
Which is best for detecting electric vehicle fires? And can these be interconnected with the rest of the homes smoke alarm system?
Hi RubLar, There haven't been specific tests done to confirm, however, it is more likely a smoke alarm will detect a fire faster than a heat alarm since in most cases smoke from a fire will the alarm before the heat will trigger a heat alarm.
To answer your second question. Yes, all the Lifesaver smoke and heat alarms can be interconnected, however, they can only be interconnected with alarms of the same manufacturer.
hi sorry for the random/stupid question.. im looking to install a heat alarm incase of fire.. would you happen to know how 'big' a fire would need to be in a room for the alarm to go off? I understand its around 53 degree C but unsure what this is in terms of size of fire (hard to answer depending on room etc i guess)
Hi Rian,
Unfortunately, this is a very complicated question, and we are unable to give you a definitive answer as there are many things that can affect the temperature of a fire, eg, what fuel is burning, how much oxygen is in the air, the size of the room and even the ambient temperature. Since it will take the air around the alarm to get to 57 degrees Celsius with the LIFHA240 there would need to be a good fire already burning in the room, and depending on the size and material in the room, that could engulf the room in a few short seconds.
Ideally, and especially if there are people living within the space, use a smoke alarm for the quickest response since smoke is produced at the very early stages of a fire and usually as a fire is beginning to burn it will produce more smoke.
Hopefully, this helps.
@@PSAproducts thank you very much for the detailed response this makes sense
Hi I am an informal fire protection consultant my answer to you would be maybe you mean how many heat alarm do you need in an area well the spacing for heat alarms is listed in the directions but some heat alarms will only activate if the temperature is heated above a certain temperature some may also have a rate of rise feature that if the temp raises to quiclkly it will activate I wish you good Luck !!!

Some thing also to consider is that the reason photo electric use is increasing is because of its low rate of failure about 4% in both smoldering and flaming fire ion failures start at 20% and get higher heat alarms have approximately zero failure in most cases it's best to have both a photo alarm and a heat alarm what hopefully what isn't detect ed by one will be picked up by the other a heat alarm cannot detect smoke
Now i know
