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
