Alarm screens are generally classified as what type of installation?

The classification of alarm screens as a "two appointment installation" reflects the typical complexity and requirements involved in setting them up. This type of installation often necessitates an initial visit to conduct site surveys, measurements, and equipment selection, followed by a subsequent appointment for the actual installation and testing of the system. The two appointments allow technicians to ensure that they properly address all aspects of the installation process, from planning to execution, ensuring that the customer receives a fully functional alarm system that meets their specific needs. This approach helps facilitate a more thorough installation experience, improving customer satisfaction and system reliability.

Other options such as one appointment or three appointment installations do not accurately capture the usual workflow associated with alarm screens. Standard installations may not encompass the nuances involved in setting up more complex systems like alarm screens that require careful planning and follow-up steps.
