The COP DAU and TOC DAU perform the same essential audio function within a digital lift emergency communication system. The main difference is their installation location: the COP DAU is fitted behind the car operating panel, while the TOC DAU is installed on top of the lift car.<\/p>\n\n\n\n

In short, choose the COP DAU when you want a compact, discreet solution integrated behind the car operating panel. Choose the TOC DAU when space is limited, easier maintenance access is important or the system serves a group of lifts.<\/p>\n\n\n\n

The right solution will depend on the available space, access to the car operating panel and your installation and maintenance requirements.<\/p>\n\n\n\n

How does a digital lift emergency communication system work?<\/h2>\n\n\n\n

When an emergency alarm is activated, the Digital Audio Unit transmits voice communication from the lift car to the alarm receiving centre through the Digital Communications Platform (DCP).<\/p>\n\n\n\n

Which Digital Audio Unit is suitable for your lift?<\/h2>\n\n\n\n

Use the following questions to identify the most appropriate option for your installation.<\/p>\n\n\n\n

1. Is there sufficient space behind the car operating panel?<\/h3>\n\n\n\n
