SIPTU Retained Fire Fighters have voted to accept proposals from the Workplace Relations Commission aimed at resolving a dispute over pay and conditions.
In a ballot of SIPTU members, 63% voted in favour of the deal.
The acceptance of the proposals follows intensive consultation last week and a secret ballot.
Since June, around 2,000 retained firefighters had been engaged in a rolling campaign of industrial action, with pickets placed across 200 retained fire stations.
Last month, they suspended their industrial action after agreement was reached at the WRC.
