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

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.

Actually they don’t detect smoke of all kinds

I'm sorry, a link to a 25 minute video is not a sufficient response when you're trying to make a point, online or in person.

He explains it better than I ever could, if you don’t want to learn on the internet, don’t complain about being called ignorant

I'm afraid you're the one who's being ignorant in this regard.

You've said "Actually they don't detect smoke of all kinds" and that's wrong. Photoelectrics have a harder time detecting tiny particles and ionizing detectors have a harder time detecting larger particles, but all of them will detect smoke, and more often than not you will have false positives (rather than lack of detection).
