Abstract: An electric circuit for monitoring and controlling of at least one elevator emergency safety for braking elevator car from moving is provided. The electric circuit installed in an elevator having a control panel, a lifting machine having at least one motor brake and emergency safety braking and floor signal (FS) device. The electric circuit includes a switching device RFS energize or de-energized depending on electric signal of said FS device. The electric circuit further includes a switching device RGX having contacts RGX-1 and RGX-2, a switching device RG having contacts RG-1 and RG-2 and a switching device RBRK for indicating the state of the motor braking(s). The electric circuit further includes contact RBRK-1 of the switching device RBRK and contacts RFS-1 and RFS-2 of the RFS switching device.
