The optional service unit serves to monitor call forwarding. The service unit would not only
indicate the emergency call acoustically but also visually. The call can be muted for
20 seconds or the additional call in the office disabled in absence.
The optional call button also includes lights to be found more easily and to confirm a
successful emergency call.
The service terminal shows unmonitored calls of several emergency calls centrally. It
reports the emergency calls acoustically and visually as plain text. Just as for the service
unit, call forwarding can de disabled on the service terminal in absence or interrupted for
20 seconds. Surface-mounted housing is optionally available.
In accordance with the Dutch standard NEN 1814, the length of the pull cord of the push-
button can be extended to 20 m using the deflexion pulley set. In Germany, this extension
is not obligatory but could be deemed necessary in certain cases. When the pull cord is
installed using the deflexion pulley set, even a person lying in the floor can send an
emergency call pulling at any point of the cord.
The emergency call system is ready for operation as soon as power is supplied. The UPS
module is only able to fully switch to emergency power supply if it was connected to supply
voltage for several hours. It could be up to 6 hours, depending on how long the
accumulator has been charged.
