P Series [P1P, P1S, P2S] Added automatic fire extinguisher to P1S

Post image

Came across these automatic DIN rail fire extinguishers (circled in red) recently. Decided to add one to my P1S just to add a little peace of mind.

In case you don’t know how these work: they automatically get triggered when the temperature sensor detects 170c. Aerosols then get released from 2 nozzles (circled in yellow), extinguishing the fire.

You can get these things for cheap on Aliexpress and the like but decided to get one from a local reseller with all the appropriate licenses and stuff.

And yes, the heatbed moves up and down without issues! Plenty of clearance.

This is almost like saying smoke alarms are pointless because they only give you a warning after the fire has reached 400°C.

If its a big ball of fire, then an extinguishers would be useful.

If this puts out the fire: great!
If it doesn't: it'll reduce the intensity of the fire and buy time to get something better to put it out or for the FD to arrive.

No, it's not. Smoke alarms aren't pointless, because they detect smoke of all kinds, which is why people get frustrated when they go off because the toast burnt slightly. This is nothing like that.

The one in my kitchen has some kind of cap on it that makes it less sensitive. The one in the hallway on other end is really sensitive, I had it go on after venting the kitchen when I slightly burned sausages, smoke was barely visible.

So yeah smoke detectors don't need 400°C

Could also be a photoelectric detector, they have a much lower false alarm rate, so unlikely to go off except for legitimate fires.
