I would like to know how to map the siren of an alarm system that is inside the building.
The tag emergency=siren starts with " An outdoor warning siren". My question is if that is appropriate for indoors?
The definition is intended for wide-area coverage, so it’s understandable. As buildings may still have outdoor alarms, it could be clarified as for the public, entire population, the local neighborhood, or the general community. The meaning is based on civil defense.
A particular problem with =fire_alarm
is it has been associated with =fire_alarm_box
, but that has been voted for a specific meaning (for public use on street outdoors, definitely connecting to the fire service) without intuitive naming. This naturally causes misuse, obvious when semicolon with fire_house
or fire_extinguisher
, phone
, and even 1 siren

Fundamentally, =fire_alarm
/ =alarm
may not be the clearest in showing whether it’s the notification device (light, sound), or the activation panel (often a break-glass unit). However on the contrary, these fire alarm “indicators” has both light and sound next to each other, so the 7+1=8 =*_bell
has limitation for not fully describing both. They can be contained in a single device with both strobe light and bell now. When they are separate, users may not want to create them individually, even if it’s you doing this detail. Furthermore, fire alarms can have speakers now, to broadcast pre-recorded voice messages.

=fire_alarm_bell
(unclear if this is actually a=siren
) Node: 8482800434 | OpenStreetMap
In conclusion, if you want to pick something used now, or ignore the light first, I would start with =fire_bell
Thank you for your answer, however, I think this siren is not for fire, but for security.
Something like this:
Is it still valid to use =fire_bell ?
Then something else. The generic emergency=alarm
in the wild has the same problem, unclear whether for activation, or notification.
man_made=loudspeaker
has been proposed , while I don’t know if it has to be capable of voice announcements. It could still be used first.
