RWA-Emergency Power Control
System
The RWA-Emergency Power Control System is the central control unit to which all the
other components are connected. The RWA-Emergency Power Control System controls the components and supplies them with power.
The type designation of the RWA-Emergency Power Control System specifies the maximum permissible output current for the drives and the number of ventilator groups that can be connected:
Type designation Maximum output
current to the drives
E 260 N2/1 2.0 A * 1
E 260 N4/1 to E 260 N4/2 4.0 A 1–2
E 260 N8/1 to E 260 N8/4 7.5 A 1–4
E 260 N12/1 to E 260 N12/2 12 A 1–2
* or 2 x E205/206 drives, E212-24 V
The number before the slash specifies the power group, the number following the slash gives the number of ventilator groups which can be connected.
Alarm group The RWA-Emergency Power Control System has one alarm group. The alarm group
consists of two lines:
• An RWA switch line
• A smoke/heat differential sensor line
If either of these lines triggers the alarm, the drives of all of the ventilator groups will be actuated in accordance with the set alarm program.
Moreover, the alarm group can be connected to an external fire alarm system. If the external fire alarm system triggers a fire alarm, it starts the same alarm program as for an alarm from an RWA switch or smoke/heat differential sensor.
Ventilator groups Depending on the version, the RWA-Emergency Power Control System supports one,
two, three or four ventilator groups. Each ventilator group has two lines:
• A drive line
• A ventilator switch line
All drives for a ventilator group are controlled jointly by one of the associated ventilator switches or by the optional timer switch.
Maximum number of
ventilator groups
18
Ventilator groups cannot be retrofitted.
Rain/wind sensor You can connect a rain/wind sensor, which closes all the windows in the event of rain
or strong winds. The ventilator switches are disabled as long as the rain/wind sensor
is active.
Signals An optional daughter card provides 3 additional contacts for signals or alarm lines:
•Alarm: On which you can, for example, connect an audible alarm or an alarm line
to the fire station.
•Fault: On which you can, for example, connect a warning lamp.
• Window Open: On which you can, for example, connect a warning lamp.

The alarm group consists of a smoke/heat differential sensor line, an RWA switch line and an input for an external fire alarm system.
E 260 N2/N4/N8/N12
The alarm from the alarm group acts on all the ventilator groups of the RWA-Emergency Power Control System.
RWA switch A maximum of four (E 260 N2/1) or ten (E 260 N4/1 to N12/2) RWA switches of type
FT 4/24 V DC can be connected in line to the alarm group. With the exception of the
last RWA switch, remove both terminating resistors from each RWA switch.
Smoke/heat differential sensor Optical smoke sensors of type RM 1003/24V DC or heat differential sensors of type
WM 1005/24V DC can be connected to the alarm group - either a max. total of 10 sensors (E 260 N2/1 to N8/4) or a max. total of 20 sensors (E 260 N12).
Both types can be used in any combination since they have the same socket. The terminating resistor, which is delivered with the RWA Emergency Power Control System
clamped in the terminal strip, has to be installed in the last socket in the line.
External fire alarm system An external fire alarm system with a floating (potential-free) make contact can be con-
nected to the alarm group.

If you change the running direction of the drives, you must also re-label all the
RWA switches.
➮ Replace the word "Zu" (close) with the word "Auf" (open) on every RWA switch.
2.4.2 Ventilator groups
A ventilator group consists of a ventilator switch line and a drive line to open and close the windows. As an option, a timer switch can be connected to the ventilator switch line.
Every drive in a ventilator group reacts simultaneously to the signal from any ventilator switch or timer switch for this ventilator group.
One ventilator group is integrated on the main circuit board. For additional ventilator groups, optional daughter cards are added.
Additional ventilator groups cannot be retrofitted; the number of additional ventilator groups must be specified in the order.

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:
Type designation Maximum output current
E 260N 2/1 2.0 A or 2 drives E205/E206/E212-24 V
E 260N 4/1 to E 260N 4/2 4 A
E 260N 8/1 to E 260N 8/4 7.5 A
E 260N 12/1 to E 260N 12/2 12 A
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.

If the rain/wind sensor is triggered:
• The ventilator switch is disabled.
• All the connected drives are run in the "Zu" (closing) direction.
The alarm program takes precedence over the rain/wind sensor. Which means in the event of an alarm:
• The windows are opened even if the rain/wind sensor is active.
• The windows will not be closed, if the rain/wind sensor is triggered after the alarm.
Connecting an external fire alarm
system
You can connect an external fire alarm system with a floating (potential-free) make contact.
If the external fire alarm system triggers an alarm, the same alarm program will be started as for an alarm from an RWA switch or smoke/heat differential sensor.
The system is reset by the Reset button on the RWA-Emergency Power Control System or with the "Zu" (close) button on an RWA switch. Before the system can be reset, the external alarm signal must be switched off so that the RWA-Emergency
Power Control System can respond properly should a new alarm signal arrive from
the fire alarm system.

1. Break out the openings in the case required for the lines.
2. Insert cable glands (2) (not included in the delivery) to achieve the required protection type (see table below).
3. Feed the cables through the case and the cable glands into the RWA-Emergency Power Control System.
4. Feed the cables to the wiring terminals (1).
The enclosure of the RWA Emergency Power Control System without cable lead-in fulfils degree of protection IP54.
The degree of protection of cable glands with sealing ring is also IP54.
Thus, the maximum possible degree of protection for the enclosure is achieved by
using cable glands with sealing ring.
The recommended sequence for connecting the components is as follows:
1. Connect the RWA switch, smoke sensor and heat differential sensor for the alarm group.
2. Connect the drives and ventilator switches (possibly timer switch) from ventilator group 1.
3. Connect consecutively the drives and ventilator switches (possibly timer switches) from the other ventilator groups.
4. Connect external equipment: Rain/wind sensor, fire alarm system, floating (potential-free) contacts for Alarm, Fault and Window Open.
30
Check connections Before connecting to the mains and to the battery, check the following:
• the component connections
• the configuration (jumper settings)
• that the cable clamps are firmly fixed
Things that are often forgotten • The two terminating resistors should only be left in the last RWA switch on the line.
F3
• Install a terminating resistor in the last smoke sensor or heat differential sensor on
the line.
• Install a terminating resistor at the "External alarm" input.
• In the case of drives without line monitoring, connect the line monitor terminal to
GND (see connection diagram).
• If a ventilator group has not been used, connect the line monitor terminal to GND
(see connection diagram).
Connecting the mains and batteries After you have connected and configured all the components and checked the con-
nections, connect the battery and mains supply.
