Just a Wheelock MT-24-LSM. Since I have nothing to do today, I will be modelling several fire alarms from my collection.
1)The horn took me about 25-30 minutes. + Strobe, about 10 more.
2)All measurements are exactly as they would be in real life.
3)There is a back, so a backbox is required (just stick that part in your walls.
4) The extrude part (where it goes diagonally-down) is a bit off. See (1)
5)There is no actual "strobe" in it. I could have made one but it would be incredibly difficult. #alarm #fire #mt24lsm #multi #multitone #tone #wheelock
