(a) Duty of city.--Except as provided in this subchapter, a city shall provide an annuity contract or establish, by ordinance, a firefighters pension fund.

(b) Monthly charge.--The annuity contract or firefighters pension fund shall be maintained, in part, by an equal and proportionate monthly charge against each member of the fire department. The charge may not exceed annually 4% of the pay of the member and an additional amount not to exceed 1% if deemed necessary by council to provide sufficient funds for payments to surviving spouses of members retired on pension, killed or who die in service.

(c) Existing organization or association.--If there is an existing organization or association for the benefit of fully paid firefighters, constituting and having in charge the distribution of firefighters pension money, an annuity contract may not be provided and a firefighters pension fund may not be established under the provisions of this section unless and until the members of the organization or association, by a two-thirds vote, elect to transfer the existing fund into the pension fund required under this section.

(d) Pension fund board.--A firefighters pension fund established under the provisions of this section shall be under the direction and control of a board of managers that shall consist of the following:

(e) Substitution.--If a city does not establish a department whose director is named as an ex-officio member of the board of managers, the director of another department or the officers of the city as may be designated by council shall be substituted on the board of managers.

(f) Terms and vacancy.--Of the first members chosen by the members of the fire department to the board of managers, one shall be chosen for a term of two years and one for a term of four years. Biennially after the initial choices, one fire department member shall be chosen for a term of four years to take the place of the one whose term expires. In case of vacancy among the managers chosen by the fire department, a successor shall be chosen for the unexpired term.

(g) Requirements.--Under regulations prescribed by the board of managers, the firefighters pension fund shall be applied for the benefit of the members of the fire department who receive honorable discharge from the fire department by reason of service, age or disability, surviving spouses of retired members and the families of members who are killed or who die in the service. A pension to an individual who is retired by reason of disability, service or age must be in conformity with a uniform scale, together with service increments as provided under this subchapter. A benefit from the fund to the family of a member who was killed or who died in service shall take into consideration the member's surviving spouse and the member's minor children under 18 years of age, if any.
