Alarm functions
During the execution of an alarm function the ventilation functions are disabled.
i
When configuring 2 SHE groups (see 3.2), the following description applies accordingly to the second group.
●
Alarm function:
Upon detecting an alarm, the actuators of the SHE group are fully extended. The indicator
r
lights up and manual call points with buzzer
S
emit a continuous tone. Repetition of cycle
a
is executed for
30 minutes (extend, briefly retract, extend again).
●
Resetting the alarm function:
Resetting is done by briefly pressing the button
Reset
r
in a main alarm
point or the Control Centre. Then the indicators
r
will go out and the buzzers
S
will be switched off.
i
If the actuators are retracted by pressing the button
z
after an alarm has been reset, ventilation can be
resumed only after 4 minutes.
●
Manual call points:
For manual alarm signalling, 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 alarm is triggered automatically (depending on the type of detector due to
smoke and/or heat detection).
If an automatic fire detector responds immediately after resetting, press the button
Reset
r
again (smoke
particles may still be present in the detector).
●
Fire Alarm Control Panel (FACP):
When an alarm is signalled by the FACP, the alarm function will be exe-
cuted in both SHE groups. The alarm is reset at the FACP.
i
Other alarm functions (“Fault = Alarm”, “Thermal Alarm”, “2-detector-dependency”, “Auto Close”) see 3.2.

Ventilation functions
i
Configuration of ventilation groups: see 3.2.
i
The ventilation position, the ventilation time and the wind and rain control are disabled as long as the function
“Automatic OFF” is enabled (see 3.2). Actuators operate only if a button
a
/
z
is pressed.
!
When performing ventilation functions, do not exceed the duty cycle of the actuators.
3.5.1
Manual ventilation
● After briefly pressing a ventilation button (
a
/
z
), the actuators of the ventilation group travel up to the end po-
sition or the set ventilation position
h
(see 3.5.2). Pressing it again stops the actuators. By pressing the but-
ton for the reverse direction of travel, the travelling direction is reversed after a brief stop.
● When pressed longer (> 1 s), the actuators travel as long as the button remains pressed. It is also possible to
travel up to the end position or up to the set ventilation position.
3.5.2
Setting the ventilation position
h
i
This setting can only be made when the system has no faults and WRC is not active.
Initially, all actuators must be completely retracted and the travel command
z
has to have finished.
● Set the travelling times towards OPEN and CLOSED to define the desired ventilation position.
Factory setting: 15 s travelling time OPEN, 30 s travelling time CLOSE.
The ventilation position can be enabled / disabled for each actuator output:
