We present a description of the new complex installation for the study ofextensive air showers which was created at the Tien Shan mountain cosmic raystation, as well as the results of the test measurements made there in2014-2016. At present, the system for registration of electromagnetic showercomponent consists of $\sim$100 detector points built on the basis of plasticscintillator plates with the sensitive area of 0.25m$^2$ and 1m$^2$, spreadequidistantly over $\sim$10$^4$m$^2$ space. The dynamic range of scintillationamplitude measurements is currently about $(3-7)\cdot 10^4$, and there is aprospect of it being extended up to $\sim$10$^6$. The direction of showerarrival is defined by signal delays from a number of the scintillators placedcross-wise at the periphery of the detector system. For the investigation ofnuclear active shower components there was created a multi-tier 55m$^2$ionization-neutron calorimeter with a sum absorber thickness of$\sim$1000g/cm$^2$, typical spatial resolution of the order of 10cm, anddynamic range of ionization measurement channel about $\sim$10$^5$. Also, theuse of saturation-free neutron detectors is anticipated for registration of thehigh- and low-energy hadron components in the region of shower core. A complexof underground detectors is designed for the study of muonic and penetrativenuclear-active components of the shower.  The full stack of data acquisition, detector calibration, and showerparameters restoration procedures are now completed, and the newly obtainedshower size spectrum and lateral distribution of shower particles occur inagreement with conventional data. Future studies in the field of$10^{14}-10^{17}$eV cosmic ray physics to be held at the new showerinstallation are discussed.
