Abstract:
1. A fire alarm system comprising: a fire alarm control panel (FACP); an addressable signaling line circuit (SLC) operably coupled to the FACP for communicating with addressable components, including a plurality of sensors; a plurality of atmospheric sensors operably coupled to the SLC and each configured to provide a potential hazard signal representative of a potentially hazardous condition, wherein said plurality of atmospheric sensors comprise magnetically activated switches; and a mobile robot configured to be addressed and dispatched by said fire alarm control panel (FACP) when the sensors generate the potential hazard signal, to an area indicated by said sensors detecting the potentially hazardous condition, the FACP dispatching the mobile robot to the area before the FACP activates a pre-set alarm, said robot having mobile sensors configured to obtain verification of the potentially hazardous condition, said mobile sensors comprising a magnet configured to activate said magnetically activated switches, to communicate a mobile sensor signal verification to the FACP, the FACP issuing an alarm signal when the FACP receives the mobile sensor signal verification.
