Any service retirement annuity, disability retirement annuity or any other annuity provided herein shall be payable in equal monthly installments as life annuities, and shall not be decreased, revoked or repealed, except for error, or except where specifically otherwise provided, or upon written request. The cost of providing death benefits for members in receipt of retirement annuities shall not be construed as a reduction in the life annuity payable to the member. The first payment of an annuity shall be made for the fraction of a month elapsing until the end of the first month; and the last payment shall be made as of the end of the month in which death occurs.
