Yes. The 2447TH-R mounts to standard electrical boxes for straightforward installation with no special hardware.
Is this horn addressable or conventional?
Conventional. It connects directly to a 24V DC NAC circuit on any conventional fire alarm control panel. For addressable or intelligent notification appliances, see the Kidde Genesis series.
