Drives
The drives of a ventilator group are connected in line. Some of the drives recom-
mended by GEZE have an integrated line monitor, which transmits an error message
to the RWA-Emergency Power Control System in the event of line break.
For the windows and smoke extraction vents you must use 24 V DC drives with an
integrated limit (end position) switch. Recommended drives are:
•
GEZE actuating, spindle and chain drives
•
Drives which conform with the GEZE specifications
Maximum number of drives:
The total number of drives on a RWA-Emergency Power Control System is limited by
the maximum output current of the RWA-Emergency Power Control System:
Ventilator switches
The ventilator switches for a ventilator group are connected in a line. Every ventilator
switch on the line simultaneously controls all the drives which are connected to its
ventilator group.
Maximum number of ventilator switches:
•
3 ventilator switches with LED, types E 50/5 or E 50/7
•
any number of ventilator switches without LED, types E 50/1 or E 50/3
Timer switch
As an option, a timer switch - such as the GEZE 2-channel timer switch - can be con-
nected to each ventilator switch line. The timer switch must be set to pulse rather than
continuous signal.
Since the timer switch and ventilator switch are considered as equal control elements,
the RWA-Emergency Power Control System will react to the last signal received.
