A laser thermal testing method and system for use in testing a fire alarm system which has a plurality of heat-sensors which are remotely distributed throughout a protected area. The laser thermal testing system includes a first laser and a second laser. The first laser generates an aiming beam of coherent electromagnetic radiation in the visible spectrum. The laser thermal testing system also includes a movable reflector which reflects the aiming beam. The movable reflector is optically coupled to the first laser. The movable reflector is first moved in order to align the aiming beam in an aligned position so that the aiming beam is reflected onto one of the heat-sensors. The movable reflector is then fixedly secured in the aligned position. The second laser generates a heating beam of coherent electromagnetic radiation in the infrared spectrum. The second laser is optically coupled to the reflector so that when the movable reflector is fixedly secured in the aligned position the second laser may be turned on in order for the heating beam to be reflected onto the heat-sensor thereby triggering the fire alarm system during a testing sequence.
