Smoke sensor and heat differential
sensor
If a smoke sensor detects smoke or a heat differential sensor registers a sharp incre-
ase in temperature, the fire alarm is triggered.
See Section 1.4, Fire alarm, for details on how to clear the alarm.
Alarm signal (optional) The RWA-Emergency Power Control System transmits an external alarm signal if the
fire alarm is triggered. This can be used, for example, to trigger an audible alarm or
the alarm can be relayed to the fire station.
External fire alarm system If your RWA-Emergency Power Control System is connected to an external fire alarm
system, this can also trigger the fire alarm.
See Section 1.4, Fire alarm, for details on how to clear the alarm.
Fault signal (optional) The RWA-Emergency Power Control System transmits an external signal in the event
of a fault. This can, for example, be connected to a warning lamp.
1.3 Ventilation operation
Opening and closing windows The windows are divided into ventilator groups. For each ventilator group, there are
one or more ventilator switches which can be used to open or close all the windows
in that ventilator group at the same time.
➮Press the Open button to open a window.
➮Press the Close button to close a window.
➮Press the Stop button to stop the opening or closing of a window.
The opening and closing of the windows is indicated by LEDs on the RWA switches
and ventilator switches in the following manner:

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 cont-
rols 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:
* 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.
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.

2.4.1 Alarm group
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-Emer-
gency 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 sen-
sors (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 ter-
minating 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.
