Installation

Be sure the system is powered off!. Refer to Figure 3.

The optional 3M™ A125 Noise Reduction board (3M part number 78-9236-6453-2) improves the inbound intelligibility of an intercom system by reducing environmental background noise from vehicles, airplanes, noisy intersections, wind, etc.

1.On the A125 circuit board, set the jumpers and switches as follows:

Set JMP1 and JMP2 to position A.

Set SW1 number 1 ON

Set SW1 number 2 ON

Set SW1 number 3 as desired:

--With SW1 number 3 OFF, the A125 is set for restaurant noise reduction.

--With SW1 number 3 ON, the A125 is set for truck stop noise , which provides more noise reduction with slightly more voice degradation.

Set SW1 number 4 as desired:

--With SW2 number 4 ON, the higher-end frequencies are increased by 3 dB. This should be set to the customer’s preference.

SW1 numbers 5 and 6 are not used.

2.Remove 4 screws on each side of Communications Controller cover.

3.Remove cover.

4.Plug Noise Reduction Module ribbon cable into Connector J12.

5.Use upper and lower mounting brackets to secure Noise Reduction Module to Communications Controller chassis as shown in Figure 3.

6.On the Model 2470 circuit board, Set JMP1 to open. LED1 (adjacent to JMP1) blinks when noise reduction module is active.

7.Replace cover and 8 screws.

2475, 2470 specifications

3M has long been recognized as a leader in innovative solutions across various industries, and the 3M 2470 and 2475 are prime examples of the company's commitment to quality and technological advancement. These products are specialized filters that provide exceptional filtration performance, particularly in environments where air quality is a concern.

The 3M 2470 filter is designed for use in respiratory protection systems, specifically in conjunction with a half or full-face respirator. Its primary function is to filter out particulates and certain aerosols, making it an essential tool for professionals working in industries such as construction, healthcare, and manufacturing. The filter boasts a lightweight yet durable design, ensuring comfort for long periods of wear. One of the standout features of the 3M 2470 is its advanced electrostatic filtering technology, which enhances its efficiency in trapping airborne particles while reducing breathing resistance. This technology not only improves the filter's performance but also contributes to increased user comfort.

The 3M 2475 filter, on the other hand, is a versatile option that combines particulate and gas vapor filtration. It is particularly beneficial for environments where both dust and chemical exposure are present. Like the 2470, the 2475 utilizes advanced filtration technology, incorporating cartridges that can effectively capture harmful gases, vapors, and particulate matter. This dual protection feature makes the 2475 filter an excellent choice for industries such as paint spraying, chemical processing, and in laboratories.

Both the 2470 and 2475 filters are designed with ease of use in mind. They can be effortlessly attached to compatible respirators and feature a low-profile design that minimizes obstruction during use. The filters' compatibility with numerous 3M respirator models ensures that professionals can easily integrate them into their existing safety gear.

In terms of characteristics, both models excel in delivering high levels of filtration efficiency, with the 2475 offering enhanced protection against specific gases. The filters are also designed to maintain a compact and lightweight profile, making them suitable for use in a variety of demanding environments. Furthermore, the materials used in these filters are both robust and resistant to wear, ensuring longevity and reliability in challenging conditions.

Overall, the 3M 2470 and 2475 filters exemplify the company's dedication to creating innovative and effective respiratory protection solutions. With their advanced technologies, user-friendly designs, and exceptional performance characteristics, these filters represent a crucial investment for professionals seeking to enhance their safety and health in the workplace.
