'Universal evac control'
'Universal evac control' is suited for horns that do not allow two-phased (multi-
channel) alarming.
For the ↑ alarming equipment (outputs, alarm devices) on the control outputs
(effects), it is possible to choose different tones for alerting ('Alert') and evacuation
('Evac').
'Phased evac control'
With 'Phased evac control', initiation of the alarming equipment (outputs, alarm
devices) is effected separately for alerting ('Alert') and evacuation ('Evac').
Application [GB]: First, all floors are warned ('Alert'). After that, the evacuation
('Evac') of individual floors is perfomed at particular intervals (phases), starting with
the floor on which the seat of the fire is located, in order to prevent blocking of the
escape routes.
This application may be different for different parts of a building.
● In the first phase the floor on which the fire is located as well as the one above
and the two top floors, all basement floors and possibly the ground floor are
evacuated.
● In additional phases, one upper and one lower floor are also evacuated at
predefined intervals. If need be, additional floors can be evacuated during the
same phase.
