Within two-particle cluster approximation for free energy and replica symmetric approach the simple model of proton-glass with different types of competitive interactions is studied. It is shown, that for calculation of thermodynamic characteristics we can use Gauss approximation for distribution function of cluster fields. For simpler model with Gauss cluster fields and weak long-range interactions (linear approximation) we study the influence of long-range interactions and random internal fields on phase diagram and its physical characteristics. Within Glauber approach expression for linear dynamic susceptibility of the model is obtained and investigated.
