DESCRIPTION OF THE SYSTEM ARCHITECTURE

Fundamental rules to follow when installing the Mosaic nurse call system

Patient call system products are associated with personal safety. They should therefore be installed by a qualified electrician, in strict
accordance with the conditions of installation and the operating instructions.

A single protection device should be installed for the entire nurse call system.
To ensure continuous operation during a mains failure, connect to an uninterruptible supply (generator and/or inverter). If there is a

mains failure longer than 1 s, all calls prior to the outage may be lost.
Note: The Mosaic nurse call system is recommended for installations with 1 to 72 directions*.

* Direction: room from which the calls originate
