'Universal sounder evac control' – 'Effects' assignments – parameters
in the 'Overview' tab
The following table describes possible parameters in the 'Overview' tab for 'Effects'
assignments:
Parameters Values Description
'Enabled' On/off
Activates or deactivates the 'Activation timeout
'manned'' parameter.
'Activation timeout
'manned''
Input field for time period
[hh:mm:ss]
Adjustment range: 0...100
min
Increments: 1 sec
The parameter specifies the time that needs to
elapse in 'Manned' operation before the assigned
alarm device is automatically deactivated again.
'Enabled' On/off
Activates or deactivates the 'Activation timeout
'unmanned'' parameter.
'Activation timeout
'unmanned''
Input field for time period
[hh:mm:ss]
Adjustment range: 0...100
min
Increments: 1 sec
The parameter specifies the time that needs to
elapse in 'Unmanned' operation before the assigned
alarm device is automatically deactivated again.
12.4.2 Phased evac. controls
A phased evac. control makes it possible to configure a complete evacuation
function for each alarm device group, e.g., on one floor. The evacuation function
always consists of a 'Alert' phase and a 'Evac' phase. The controls provide a cause
group for each evacuation phase:
Cause group Description
'Alert' phase:
● 'Causes ALERT''
This cause group contains all causes which result in
the assigned ↑ alarm devices playing a warning
signal.
'Evac' phase:
● 'Causes EVAC'
● 'Causes EVAC FIRE
(+DEGRADED MODE)'
These cause groups contains all causes which
result in the assigned ↑ alarm devices playing an
evacuation signal.
The assigned causes within these cause groups are assigned with a simple OR
function. Certain events from the following event categories can be assigned as
causes:
● 'Events 'Alarm and Pre-alarm''
● 'Events 'Technical message''
● 'Events 'Activation''
● 'Events 'AVC and IC''
Furthermore, inputs can also be assigned as causes for the activation of alarm
devices.
The Engineering Tool provides two different controls which can be used to
implement phased evac. controls. The selection depends on which alarm devices
or sounders are installed and which functions are required.
