PROBLEM TO BE SOLVED: To prevent erroneous alarm and wrong interlock by making it selectable whether to shift to a warning mode or a smoke prevention and smoke exhaust interlocking mode in a period from turning on of a power switch until the lapse of a prescribed time in a fire receiver. SOLUTION: This fire receiver having a lead-out monitoring line to which a fire detector is connected and provided with a display operating part, is provided with: the power switch; a timer means that is started when the power switch is turned on to clock a prescribed time; and a control processing part which displays a selection instruction massage for guiding the selection of operation continuation or operation stop on the display operating part until the timer means stops because it has counted time out after the power switch is turned on, shifts the fire receiver to the warning mode at the point in time when the operation continuation is selected while inhibiting processing of the fire receiver at the point in time when the operation stop is selected, and automatically shifts the fire receiver to the warning mode after the timer means stops because it has counted time out.
