User manual ACR ELECTRONICS MS-2000M

[. . . ] Purpose The light is designed and intended to provide aircrew and other personnel with a high-intensity visual distress marker signal for use in the event of unscheduled abandonment of aircraft in isolated regions and other emergency and/or special operational mission situations. General Characteristics The MS-2000(M) Distress Marker Light is a lightweight, compact, battery operated, portable unit that is designed to be used as a multifunctional light during emergency and/or clandestine special mission situations. The light is designed to attract attention, to assist in location and to facilitate personnel rescue operations in both overt and covert operations. The light system consists of a main body case containing the electronics, lamp, batteries and the flashguard (FG) shield containing one infrared (IR) and one blue filter. [. . . ] Initial A ten minute MANUAL flash rate test is a one-time requirement for all new MS-2000(M) lights received from supply stock. This test is required for initial acceptance of the light and is conducted to insure that the light is capable of sustained operations. Select the white light function (See Figure 2), turn the switch to ON and observe that the strobe lamp flashes. Allow the light to flash for nine (9) minutes, and then manually count the flash rate of the strobe during the final one minute of the test. This rate should be 50 ± 10 flashes. It is not necessary to directly observe the light flashes during this evaluation. This inspection should be performed in a dark room or enclosure. If any light fails to meet the 50 ± 10 flash rate requirements, check the batteries and, if necessary, replace both batteries and repeat the test. Additionally, the battery contacts in the battery well should be checked and, if necessary, cleaned with a small brush. Hold vertical while using brush so that any debris falls out of the light. If battery replacements or cleaning contacts fail to correct the problem, discard the light in accordance with local procedures. Periodic Normally this test is accomplished in conjunction with other life support survival kit/vest test requirements and/or as required by specific MAJCOM directives. This test may be accomplished MANUALLY or AUTOMATICALLY by using the TS-23/A Strobe Light Tester. If the test is to be conducted MANUALLY, follow the test procedures as outlined in paragraph 2a above, except limit the test duration to two (2) minutes. Again, a flash rate of 50 ± 10 flashes per minute is the acceptable test rate. If using the TS23/A Strobe Light Tester for this inspection, the light can be tested in the TS-23/A with the IR filter in place, by placing the lens/filter over the inspection window on the TS-23 face label and then Y1-03-0146E 7 pressing the trap door down to turn the TS-23 "ON", or by removing the flashguard shield and inserting it into the tester. This is accomplished by separating the main body of the light from its flashguard shield. This separation is performed by holding the main body of the light with one hand while grasping the flashguard shield with the other and pulling in opposite directions. After separation, insert the top of the light into the trap door on the top of the TS-23/A, insuring that the xenon lamp is fully inserted into the tester. Turn the light switch ON and note the numerical reading recorded on the digital readout of the tester. An acceptable reading between 100-150 is required and equates to a flash rate of 50 ± 10 flashes per minute. If a reading of less than 100 is noted, replace both batteries and, if necessary, clean the battery contacts in the light, then repeat the test. [. . . ] *Five years for the following products: EPIRB, PLB, S-VDR, SSAS. USEFUL LIFE POLICY The typical service life of a properly maintained Product is limited to 12 years from date of manufacture. Products that are 12 years and 1 month or older from date of manufacture will not be serviced by ACR or our Battery Replacement Centers. A Product that is 12 or less years old from date of manufacture will be serviced as long as the unit appears fit to be placed back into its final operational cycle. Service includes the replacement of those items that must be replaced at service intervals and the verification that the device appears to be in good mechanical and electrical working condition by an ACR authorized service technician. NOTICES ACR Electronics diligently works to provide a high quality Product Support Manual, however, despite best efforts, information is subject to change without notice, and omissions and inaccuracies are possible.
