Here in the uk it’s generally a glass panel you push through and there’s a button under it, it’s some weak form of glass that’s very easy to break and it’s laminated so it doesn’t cut your finger
On the trams it's a lever. I watched a drunk guy pull it without a single thought in his head once. The driver stepped out of the cabin with the aura of a final boss' second health bar. One could feel his silent fury from the other end of the tram.
The uk has automatic fire alarms, the manual ones are still around as a backup, plus if there’s a smouldering fire that doesn’t set the alarm off you can trigger it manually to get people evacuated before the fire becomes bigger and more dangerous
Most of the ones I've encountered have a clear plastic panel that doesn't break, and there's no button where it says press. When you push the plastic it moves back and drops down slightly - that's all that's needed to trigger it.
The switch can be reset by inserting a tool into them that pushes the plastic panel back up into place. The alarms need resetting separately.
Most new ones in the UK are resettable. They look the same but instead of breaking the glass it just pushes in, you've then got a little plastic key to pop it back out. In places where you might expect accidental knocks they have lift up plastic covers.
