Seems like mounting a smoke detector near the printer is a good idea. The two major groups are photoelectric and ionization. Has anyone looked into which type is better for this use, in terms of both sensitivity and false alarms? Does it differ for ABS vs PLA vs Nylon? I haven't tried burning any of them. Or a printer.

Whatever you do, stay away from the Nest wifi units. The reviews on Amazon say that they have serious problems with both false alarms and not alarming during actual fires.....

Haven't tried it with filament, but a photo smoke is FAR less likely to false-alarm than an ion. A photo responds to to smoldering fires and is much more likely to repond to a real fire before an ion will.

Just my 2 cents....

I have installed an ionisation type fire detector that has a relay and cuts power to the printer. I have been using it for over 6 months without any problems. I tested it with a lighted match but it has never been used in anger.
