The effects of locally broken spin symmetry are investigated in one-dimensional nonequilibrium kinetic Ising systems via computer simulations and cluster-mean-field calculations. Besides a line of directed percolation transitions, a line of transitions belonging to N-component, two-offspring branching annihilating random-walk class [formula presented] is revealed in the phase diagram at zero branching rate. In this way a spin model for [formula presented] transitions is proposed.
