Manual call points, automatic fire detectors and Fire Alarm Control Panel 

 

Manual call points:

 For manual alarming, break open the glass of the manual call point and press the control 

button until the indicator 

r

 confirms the detection of the alarm. 

For maintenance work, the door of the manual call point can be opened with a key. 

 

Automatic fire detectors:

 The alarming takes place automatically based on smoke and / or heat detection 

depending on the detector type. 
After resetting, if an automatic fire detector responds again, repeat the reset step (smoke particles may still 
be present in the detector). 

 

Fire Alarm Control Panel (FACP):

 When the FACP generates an alarm, the alarm function is activated. 

Resetting of the alarm is done at the FACP.  

 

3.4.2

 

Repetition of OPEN cycle in case of alarm 

  The OPEN command is executed over a period of 30 minutes as follows to ensure opening of the actuator in 

case of alarm, even at adverse circumstances (e.g. frozen seals): 
The actuators travel in the OPEN direction for 2 minutes, briefly in the CLOSE direction and following for 2 
minutes in the OPEN direction once again, and so on.

Ventilation functions 

i

  The ventilation position, the ventilation time and the wind and rain control are disabled if the function “Auto-

matic OFF” is enabled (see 3.2). Actuators only operate as long as a button 

a

 / 

z

 is pressed. 

!

  When performing ventilation functions, do not exceed the duty cycle of the actuator output and the actuators.

  

 

3.5.1

 

Manual ventilation 

  After briefly pressing a ventilation button (

a

 / 

z

), the actuators travel up to the end position or the set ventila-

tion position 

h

 (see 3.5.2). Pressing it again stops the actuators. By pressing the button for the reverse 

sense of travel, the travel direction is reversed after a short stop. 

  When pressed longer (> 1

s), the actuators travel as long as the button is pressed. It can also be travelled up 

to the end position or the set ventilation position (see 3.5.2). 
 

3.5.2

 

Setting the ventilation position 

h

 

  Set the travel time toward OPEN and CLOSE to define the desired ventilation position. 

Factory setting: 15

s travel time OPEN, 30

s travel time CLOSE. 

i

  Return to factory settings: Press button 

h

 for longer than 3

s. The display briefly shows 

L

.  

Disable the ventilation position: Press button 

h

 for longer than 6

s. The display briefly shows 

?

  Setting the travel times: Briefly press button 

h

 to enter programming mode (display: 

L

). 

  Open the actuators by briefly pressing the button 

h

 or a ventilation button 

a

. Press the button once more 

when desired ventilation position is reached. 

  Close the actuators by briefly pressing the button 

h

 or a ventilation button 

z

. Press the button once more 

when all actuators are completely closed. The display 

L

 extinguishes. 

  The actuators automatically travel to the ventilation position for verification and then close again. 

i

  This setting can only be made when the system has no malfunctions and WRC is not active. 

Initially, all actuators must be entirely closed. 
Programming mode is cancelled automatically after 6 minutes without button activity or manually by dou-
ble clicking on the button 

Reset

 

S

Use the button 

h

 to set if a changeover contact is used for ventilation. 

 

3.5.3

 

Setting the ventilation time 

D

 

  Use a screwdriver on potentiometer 

D

 to set ventilation time to between 5 and 30 minutes. The actuators 

close automatically at the end of the set time. Turn left to disable ventilation time (= factory setting).
