P-503BS

Recording function of P-503BS

The P-503BS records speech signals and time information during operation. In aviation use, the recorder can be connected to onboard communication circuits to capture crew voice communications and related timing signals. The system is intended for continuous recording, allowing speech information to be stored throughout operation of the equipment. The recorder belongs to the P-503B family and is used where wire-based voice recording equipment is specified by documentation.

P-503BS as a modification of the P-503B family

P-503BS is a modification within the P-503B recorder family, which also includes P-503B and P-503BZ versions. The P-503BS version is intended for applications where the recorder configuration differs from the standard P-503B installation. Exact differences between versions should be confirmed through the product passport and applicable technical documentation, since installation layout, protection requirements and equipment composition may vary by system configuration.

Wire recording medium of P-503BS

The P-503BS uses a wire recording medium for storing speech and time information. The recorder operates with wire type 5.4 according to applicable documentation and provides continuous recording for not less than 9 hours. The wire medium moves at a specified linear recording speed, allowing the system to record audio-frequency information in the speech band. This recording principle is characteristic of earlier onboard voice recording systems before the wide use of solid-state recorders.

P-503BS system composition and optional beacon

The P-503BS set may include the UZ P-503BS recording unit, PU P-503BS control panel, mounting frame, wire cassette, empty cassette, cassette case and documentation. The product design allows installation of a PAM-6k underwater acoustic beacon, which can be used to locate the recorder underwater at depths of up to 6000 meters, where specified by system configuration. The exact scope of supply should be checked against the passport and delivery specification.

Identification and ordering of P-503BS

The recorder may be referenced as P-503BS or П-503БС. These designations refer to the same product type. For correct supply, it is useful to specify whether the request concerns a complete recorder set or separate components, such as the recording unit, control panel, mounting frame, wire cassette, empty cassette, cassette case or documentation. The required configuration should be confirmed by product passport and system documentation.
