A marker is provided for use by emergency service personnel entering a room of a building, to keep the door from latching closed while he/she searches the room, and later help him find the door to exit the room, and to indicate to other rescuers that a search is in progress or has been completed. The marker includes a housing (12, FIG. 1) and a door clamp (14) mounted on the housing and constructed to fit on a door to prevent complete closing of the door. The housing holds an audible alarm generator (20) which generates sound beeps to help a searcher find the door in an environment of thick smoke. With the door clamp holding the door ajar, the sound beeps can be heard from outside the room, so another searcher can determine that a search is in progress. The alarm is settable to generate a different pattern of sound beeps, to indicate that a search is in progress, or has been completed. It also generates light flashes. The door clamp can include a length of wire that extends around the outer edge of a door. The wire door clamp can be pivoted on the housing between a stowed configuration wherein it lies adjacent to the housing before mounting compactly on a searcher's belt, and in a deployed configuration wherein it projects from the housing and can clamp to a door.
