How can the leader module control the elevator landing?
The module leads to the 2 line of the control cabinet and receives two signals on the fire escape signal. The elevator brand is different and the terminals are different.
The working principle of elevator landing system:Use the control module to operate the elevator normally. When a fire occurs, the normally open point is closed, and the elevator makes a forced landing command, which breaks down to the first floor. The elevator fire switch is connected with the landing point in series (usually closed), when firefighters open the elevator fire switch, will damage the control module closed point, the elevator back to normal use.
Elevator landing is generally provided by the elevator manufacturer landing interface and feedback interface (in the elevator control cabinet), provided by the fire control module normally open output, and achieve landing. Should be installed by the professional elevator construction units, debugging, do not own wiring, once the error will lead to damage to the elevator control panel.
Two output lines of the control cabinet are connected to the fire control module, which is controlled by an elevator, a fire control linkage relay and two fire lines when the fire signal is in use.
