Additional UL 609 installation requirements
The alarm housing for a mercantile alarm system without a
remote alarm transmission connection shall be mounted on
the outside of the building, visible from a public street or
highway. It shall be accessible for examination and repair. It

having jurisdiction over the protected property or
b) A central station or residential monitoring station
complying with the Standard for Central-Station Alarm
Services, UL 827.
