摘要：The invention relates to a fire alarm (F) comprising at least one sensor (6, 14, 15)for detecting fire parameters and an evaluation circuit (7) which triggers an alarm signal ifa defined first value is exceeded by a corresponding fire parameter. The at least onesensor (6, 14, 15) also monitors a second, greater value of the fire parameter concernedand if said second value is exceeded triggers an alarm signal which indicates that acorresponding escape route can no longer be used. The fire alarm system comprises acentral unit (12) to which fire alarms (F) are connected and an escape route indicatorsystem with adjustable indicator means (13). In the area of the escape routes theinvention further provides for fire alarms, referred to hereafter as escape route

indicators (F), for the additional monitoring of fire parameters for life-threatening values,and/or means for monitoring the people flow along a corresponding escape route,referred to as people flow meters (P). The indicator means (13) are controlled on thebasis of said additional monitoring.
