B610 – EMERGENCY FIRE SERVICE
Emergency Fire Service
There are the following modes:
A) Fire drop evacuation with one fire evacuation floor ( Priority-1)
B) Fire drop evacuation with two fire evacuation floor ( Priority-2)
C) Fire drop evacuation with three fire evacuation floor ( Priority-3)
D) Dynamic fire drop evacuation with passage of the fire source
E) Dynamic fire drop evacuation without passage of the fire source
UNTIL THREE FIRE DROP LEVELS WITH DIFFERENT PRIORITY
With fire drop evacuations it turned out that 3 fire drop floors with different priority meet the requirements
with plants up to 16 stops. If the first drop entrance is active ( +24V DC level) then the cab drives into
the adjusted 1 fire evacuation floor and the door of the adjusted door side opens. Outside and interior
control is deactivated. Further actions only after order of rank. If the +24V DC level leaves at all fire drop
entrances then the plant returns automatically to normal operation. If the second fire drop entrance is
active, or first and second fire drop entrance actively then into the second fire drop floor one drives. After
with all fire drop entrances the + 24V DC level leaves, the plant returns automatically to normal opera-
tion. During the 3 Fire evacuation entrance equivalent is acted. All entrances for the fire drop evaculation
know High actively ( normally open contacts or as Low actively ( openers) are adjusted.
DYNAMIC FIRE DROP EVACUATION
During the dynamic fire drop evaclation floor fire alarms are present in each stop. It is present a main
evacuation floor, into which in principle one evacuates. The exceptions consist of the fact that it burns
in the main evacuation floor or on the trip to the main evacuation floor the fire source to be driven. In the
sofware two are present dynamic fire drop evacuations. Those can driven through the fire source the
other one stops above the fire source.
Fire evacuation under emergency conditions
In case of a fire evacuation, if the case comes to the emergency, the fire-evacuation levels are ap-
proached, in accordance to the priorities. For a composite of several plants, can be disposed of power
capacity of emergency diesel to be evacuated as a rule only in succession.
A special case is the emergency evacuation with UPS dar. On hydraulic elevators with single-phase
UPS can take place only in the downward direction of evacuation. There is no evacuation level in the
lowest level, education levels should be avoided in the evacuation level by using a One-Way-Blocked-
Valve. As an example of a 4-stop hydraulic system may be the response of the system in case of fire
emergency condition shown below:

PARAMETER: OPEN DOORSIDE
In this parameter the door position is adjustable after arrival in the evacuation level. With only door
side in principle the door is opened always. With two existing door sides it can be decided whether
only the door side 1 or only the door side 2 or both doors are open.
PARAMETER: PIECO BUZZER
If you activate this parameter the piezo buzzer of the carpanel-unit ITR can switch on, if there is an
emergency fire service travel.
