Evaluation of the system events

Deviations from the normal operation mode are recognized as a system event.
System events are allocated to the following event categories:

'Isolation'
A detector zone has been switched off

'Test'
A detector zone is switched to Test
Operation
↑ 'Technical message'

Alarming
The different fire alarms and system events are verified independently from one
another. Depending on the configuration, local alarming or direct or delayed global
alarming is actuated.
● Local alarming:
Local ↑ alarming equipment (e.g., acoustic or optical alarm devices) is
actuated in order to call up immediately available intervention personnel
(e.g., in-house staff) and to alert people of a possible fire hazard.
● ↑ Global alarming:
Global alarming equipment (e.g. remote transmission) is actuated and external
intervention forces (e.g. the fire brigade) are alerted.
The following points influence the type of alarming:
● Configuration of the alarming process
● Position of 'Manned operation'/'Unmanned operation' operation mode
– 'Manned operation': Personnel present on site
– 'Unmanned operation': No personnel present on site
● Type of alarm activation (automatic or manual)
Control
In the event of fire it makes sense to initiate first, decisive actions automatically.
Automatic measures are carried out by controls, e.g., by the control of building
services, evacuation or ↑ extinguishing.
