The annuity shall be paid without regard to the fact that the death of the deceased fireman parent may have occurred prior to the effective date of this amendatory Act and shall be paid monthly in an amount equal to 15% of the current annual maximum salary attached to the classified civil service position of fire fighter if no widow survives and 10% of such salary while the widow survives and no age limitation in this Section shall apply to a child who is so physically or mentally handicapped as to be unable to support himself; provided, if annuities for the widow and children of a fireman who dies on or after the effective date and whose death has been the result of an act or acts of duty performed on or after said date, or for the children in any such case wherein a widow shall not exist, computed at the rates hereinbefore stated, would exceed the final annual salary of a first class fireman, (one who receives maximum salary for classified civil service rank of fire fighter), the annuity for each child shall be reduced pro rata so that the combined annuities for the family of the fireman shall not exceed such amount; and in the case of the family of a fireman who dies on or after said date and whose death is the result of any cause or causes other than injury incurred in the performance of an act or acts of duty in which annuities for such family, computed at the rates hereinbefore stated would exceed 60% of the final annual salary of a first class fireman, the annuity of each child shall be reduced pro rata so that the combined annuities for the family do not exceed such limitation.
