Abstract: Systems and methods for detecting tampering with a security device are provided. Some systems can include detecting an object within a detection range of one or more sensors of the security device, analyzing position data from the one or more sensors, wherein the position data is indicative of a position of the object relative to the security device, determining whether the positon data indicates that the object is approaching a security device, and when the position data indicates that the object is approaching the security device, issuing a warning signal.

Abstract: A method of installing a projected beam detector can include providing a radiant energy source, providing a reflector, and projecting a radiant energy beam from the source to the reflector. A multi-pixel sensor or camera can be provided. The beam can be reflected from the reflector back to the sensor. A distance between the reflector and the camera can be determined based on a size of an image of the reflector incident on the camera. Where incident intensity corresponds to expected intensity for a predetermined distance, a sensitivity can be set based on the predetermined distance.

Abstract: An improved fire detector test device and methods for conducting field sensitivity and functionality testing of a fire detector in-situ are provided. The test device can include ambient condition or stimulus generating devices and a programmable processor, wherein the programmable processor can identify information about a detector under test, wherein the programmable processor can obtain a configuration file based on the identified information about the detector under test, wherein the configuration file can identify a combination, level, or rate of a plurality of stimuli that cause an alarm in the detector under test, and wherein the programmable processor can execute the configuration file to cause the ambient condition or stimulus generating devices to generate and emit the plurality of stimuli in the combination and at the level and the rate identified in the configuration file.
