b. SITUATION 2: EXTERNAL FIRE CONTACT AND LIFT WITH ALTERNATIVE EVACUATION
FLOORS
Enter the menu "SPECIAL FUNCTIONS" submenu "FIREFIGHTERS" and set:
The first evacuation floor
- The Access (if there are multiple doors)
- The stand-by state of the key switches (keys are optional) (use NO)
- The operation EN 81-73
- Additional evacuation floors (up to three different) in priority order
- Connect the wiring as indicated in the electric diagram: the contacts of sensor must be connected
to the BDU’s input FIRE-GND. (In case of LOP’s parallel wiring must be used an 16IO expansion
board in the controller). In case of floors not managed by the control unit, the corresponding inputs
must be shunted (if the fire sensors are programmed with NC contact) .
The activation of one of signals:
• POM Key (optional contact)
• FIRE (of any of the BDUs)
will start PHASE1 of the operation (also called evacuation) and will not allow car calls without the
activation of the fire-fighters key-switch in the car. The evacuation floor could be different according the
rule:
• If FIRE of main floor is not active => evacuation to main floor
• Else, If FIRE of main floor is active => evacuation to alternative floor (the first with FIRE not
active)
In case of multiple FIRE inputs active on all of alternative floors, it will be used the main evacuation floor.
During the evacuation to a floor (when car is moving), if the corresponding input has the FIRE active,
destination floor will be changed according the same rules.
Lift stops at evacuation floors, with door open (could be possible to set closed parking).
Lift comes back in normal mode when the external signals (FIRE and optional POM/FIREMAN) comes back
in the inactive status.
