Disabled Refuge
A disabled refuge or fire refuge is an area within a building that is designed as a safe location where a person unable to use the stairs unaided can wait in relative safety until they can be assisted in their evacuation. Refuges are normally located in or adjacent to a protected staircase which is used as a fire exit route. A disabled refuge EVC (emergency voice communication) system is the equipment that provides the means of communication between the disabled refuges and the control room. It is an intercom system with special features to increase usability and reliability in the event of an emergency.
