The Status Light system consists of one or two flashing red LED main status lights visible from any direction of approach and on any landing heading. Additional PRL-AX-LSM repeater lights may be placed at the helideck. If a condition exists on an installation which may be hazardous for the helicopter or its occupants a visual warning system should be installed. The aeronautical meaning of the flashing red light is either Do not land, aerodrome not available for landing or Move clear of landing area. The system may
be automatically initiated by means of a remote alarm signal (by others) as well as manual activation. All castings are aluminum, all hardware is stainless steel and the lens is glass.
SPECIFICATION
The LED red status light system shall comply with UK CAA CAP 437. All exterior aluminum cast beacon parts shall be corrosion resistant. The repeater lights shall be treated for marine conditions by cleaning per US MIL method III of TT-C-490, chromate priming per US MIL-C-5541, epoxy powder base coat and glossy polyester powdercoat finish coat in color RAL 6003 (FED-STD-595 color #14097). Oven cured per US MIL-PRF-2471 2A. There shall be no exterior plastic parts; all shall be cast aluminum, glass and stainless steel.
The main status lights shall flash in sync if two or more are installed. For each main status light there shall also be installed a reduced intensity status light which will similarly synchronize flashing when in use. Additional repeater lights may be installed at the landing area and shall not exceed 150 mm in height. The repeater lights shall be at the reduced intensity level.
The system may be switched ON by a remote signal or manually. When ON, the stem may be manually switched to reduced intensity. After 30 minutes, the system will automatically revert to normal intensity. Failure of any light will display as an alarm at the controller.

Options —ROS and —ROSAX Remote Override Station
Provides for emergency remote manual operation of the status light system. When ordered, this station uses line voltage and connects to the "RTO" terminal block in the PSL system control unit. For a third party detection system intended to automatically activate the PSL system, the detection system control wire must provide line voltage matching the PSL to the ROS. The ROS switch will normally be set in the AUTO position, but may be manually switched to ON.
Note: For PSL systems without the ROS option, the third party detection system control wire connects directly to the "RTO" terminal
block in the PSL system control unit.
