Overview of the RWA-Emergency Power Control System Function The RWA-Emergency Power Control System controls the extraction of smoke and heat (RWA) from staircases, factory halls, etc. Windows and smoke extraction vents are controlled for normal ventilation operation. If a fire alarm is triggered, the windows and smoke extraction vents are automatically opened or closed, depending on the configuration of your RWA-Emergency Power Control System.
1.2.2 Components for ventilation operation Drives The drives open and close windows and/or smoke extraction vents. Ventilator switches The user can operate the window drives using the ventilator switches. Timer switch If a timer switch is connected, windows can be opened or closed at preset times. Rain/wind sensor If a rain/wind sensor is connected, all windows will be closed in the event of rain or strong wind.
Smoke sensor and heat differential If a smoke sensor detects smoke or a heat differential sensor registers a sharp incre- sensor 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.
Rain/wind sensor If a rain/wind sensor is installed, the windows will close automatically in the event of rain or strong wind. As long as the rain/wind sensor is active, the windows cannot be opened with the ventilator switch. In the event of a fire alarm, the windows will also open when the rain/wind sensor is active.

Stopping the fire alarm You can clear the alarm condition in two ways: • Reset the RWA-Emergency Power Control System. • Reset any RWA switch. When the alarm condition has been cleared, the audible alarm signal stops and the ventilator switches are again useable. GEFAHR If the system is not fully reset (the red fire alarm LED is still lit), the system will not function properly if a new alarm is triggered!

When replacing the batteries, use only batteries recommended by GEZE. Disclaimer If any changes are made to the system by an unauthorised person, or if components other than GEZE original parts or GEZE recommended batteries are used, GEZE shall not be liable for any resultant damage.
Storage Storing the RWA-Emergency Power • Store the RWA-Emergency Power Control System in a protected area. Control System • If the unit has already been in use: ➮ Disconnect the RWA-Emergency Power Control System from the mains and remove the battery fuse (see Section 2.5.4, Electrical connection). Storing lead gel batteries The lead gel batteries will discharge automatically when stored.
Components of the RWA-Emergency Power Control System The RWA-Emergency Power Control System controls the extraction of smoke and heat (RWA) from staircases, factory halls, etc. Windows and smoke extraction vents are controlled for normal ventilation operation. In the event of a fire alarm, the windows are automatically opened or closed.

Connection options and configurations Before the installation, plan all the connections and the configuration of the RWA- Emergency Power Control System. The various options are explained in the following sections. Discuss the design with the operator. Afterwards, complete the configuration table found in the Appendix.
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.
Setting the direction the drives should You can configure the direction that the drives will run in the event of an alarm: run when the alarm is triggered ➮ The drive direction is set with Jumper XB1 at the back of the main circuit board. E 260 N2/N4/N8/N12 Jumper Position...

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.
2.4.3 External equipment You can connect external equipment to the RWA-Emergency Power Control System. This equipment can then either send signals to the RWA-Emergency Power Control System or receive signals from it. • Rain/wind sensor (floating (potential-free) make contact) (1) •...

Connecting alarm contacts for Alarm, There are 3 floating (potential-free) alarm contacts for output signals: Window Open and Fault Alarm, Window Open (optional, cannot be retrofitted) and Fault. You can connect signal lamps, audible alarms or alarm signal lines to the fire station to these contacts.

2.5.3 Configuration DANGER Risk of death through electrical shock! Damage to sensitive components! ➮ Disconnect the mains supply for the RWA-Emergency Power Control System and take precautions that it is not reconnected while you are working. ➮ Remove the battery fuse. Before carrying out any configuration changes or expansions, you must isolate the RWA-Emergency Power Control System from the mains power and remove the bat- tery fuse.

Things that are often forgotten • The two terminating resistors should only be left in the last RWA switch on the line. • Install a terminating resistor in the last smoke sensor or heat differential sensor on the line. • Install a terminating resistor at the "External alarm"...
Function test Before handing over the system, you must test all the functions of the RWA-Emer- gency Power Control System. These tests must also be performed during the annual maintenance work. DANGER Risk of death through electrical shock! ➮ Before touching terminals or mountings, switch off the mains circuit and take precautions to prevent others from switching it back on.
Operating states and faults The operating state and any faults are shown on the 7-segment display of the RWA- Emergency Power Control System. If several states or faults occur at the same time, the display will cycle through them one per second. Operating state codes The operating state codes provide information regarding the various alarm states of the RWA-Emergency Power Control System and about the rain/wind sensor.
