A novel portable light beam projector device, related system apparatus, and attendant novel method for wide variety use in conjunction with military vehicles, to establish optimum placement of optical fire detection sensors relative to installation of the vehicle's fire suppression system. These inventions are similarly usable to novelly establish corresponding optimum placement of various optical type intrusion and/or fire-detection sensors to similarly protect various confidential areas including storage facilities and attendant personnel/equipment/data and the like whether of a military, industrial or commercial character. Each light projector device has an adjustable tubular shroud to adjustably focus the light beam cone angle. The desired cone angle of the light beam is initially set by use of associated system apparatus including an associated light beam calibration chart and some optional projector support stands. The cone angle adjustment feature enables the user to essentially duplicate the corresponding normally invisible field-of-view of various types of optical sensors to be installed.

A nozzle for discharging vaporizable liquid fire suppressant material tow a flame area to be suppressed. A nozzle includes internal mechanism for forcing an insulator shroud around the liquid fire suppressant while the suppressant is still within the nozzle. The shroud insulates the liquid material while the liquid stream is traveling toward the target flame, thereby preventing premature flashing or vaporization of the liquid. A particular aim of the invention is to increase the penetration distance, i. e. , travel distance before the liquid is dissipated.

A laboratory testing mechanism for determining conformance of an optical iation detector to prespecified time response requirements, comprising an electrically-operated shutter and a fast-moving rotary disc located between a radiation source and the detector under testing. Proximity switch associated with the disc provide electrical signals representing the time at which the window of the detector is initially exposed to the radiation source and selected elapsed time intervals thereafter.
