1.Light Leakage Test

With the IR filter in its operation position (See Figure 3), turn the switch ON and observe that no light is transmitted through the sides of the case or the flashguard shield. Turn switch OFF. No light leakage is allowed in the IR mode. If necessary, replace the flashguard shield assembly and repeat the test. If a new flashguard shield fails to remedy the problem, the light is to be condemned and discarded in accordance with local procedures.

2.Flash Rate Test a. 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. Repeat the test again. If battery replacements or cleaning contacts fail to correct the problem, discard the light in accordance with local procedures.

b.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

MS-2000(M) specifications

The ACR Electronics MS-2000(M) is a state-of-the-art survival radio beacon designed to ensure the safety of individuals at sea and in remote locations. This device is a beacon that transmits distress signals to search and rescue (SAR) authorities, facilitating fast response times during emergencies. One of its standout features is its compliance with the international Cospas-Sarsat distress beacon standards, ensuring reliability and effectiveness for users worldwide.

One of the main characteristics of the MS-2000(M) is its Dual Frequency capability. It transmits on 406 MHz and 121.5 MHz frequencies, allowing for long-range detection by satellites while still being picked up by conventional receivers during proximity searches. This dual capability significantly enhances the chances of a successful rescue.

The MS-2000(M) is designed to be both rugged and compact, weighing only 1.5 pounds and featuring an IP68 waterproof rating, which means it can withstand harsh marine environments. Its versatile design allows for easy attachment to life vests, lifeboats, or even personal carry bags, ensuring it is always accessible when needed. The unit also incorporates a built-in GPS, which provides accurate location data, further aiding SAR teams in pinpointing the exact position of the beacon.

Another significant technological advantage of the MS-2000(M) is its exceptional battery life. The device is equipped with a lithium battery that can last up to 48 hours in an activated state, ensuring prolonged transmission of distress signals. Additionally, the beacon features a self-test function, confirming that the unit is operational and ready for use at a moment's notice.

Moreover, the MS-2000(M) is designed with user-friendliness in mind. It includes a simple activation process that can be conducted even in high-stress situations, ensuring that individuals can send out distress signals promptly. The beacon is also compatible with various mounting options, providing users with flexibility depending on their specific needs.

Overall, the ACR Electronics MS-2000(M) is an essential piece of safety equipment for anyone who ventures into open waters or remote areas. Its advanced features, robustness, and reliable technology make it a trusted companion for sailors, adventurers, and aviation personnel alike. By investing in the MS-2000(M), users are equipping themselves with a powerful tool designed to save lives in emergency situations.
