对电梯和消防联动的一些认识（Some understanding of elevator and fire linkage） Some knowledge of elevator and fire linkage The ordinary elevator only need to add a control module, this module to lift a switch signal, let it down to the first floor and opened the door to evacuate, the elevator will feedback to the control module of the switching signal, after the smoke two bus to a switch signal, shunt tripping power off.

Elevator landing can use multi line module or modules, module after the action of the internal relay to the elevator control cabinet with a contact closure signal, the elevator control board according to signal will lift near floor and then lift straight to the first floor, non fire elevator should be cut off, often not lift elevator manufacturers set the feedback signal to a landing layer, only by setting off delay time in the fire program, the power cut off shunt trip with total open cut off the elevator machine room distribution box Lift a book with understanding: 3.3.2.10 emergency power leveling device When the power is off, the elevator will open the door to the nearest floor to ensure normal passengers to leave.
