What code is used for Tru II detection mode inside interlocking?

• A. 100 code
• B. 50 code
• C. 25 code
• D. 150 code

Answer: (B)

Tru II detection mode inside interlocking uses a specific signaling code to convey detector state to the interlocking logic. This mode is associated with the fifty code pattern, which the interlocking interprets as the correct representation of occupancy or detector status for Tru II. The other codes correspond to different detection modes or signaling states and would not be interpreted correctly for Tru II. So the fifty code is the standard choice for Tru II detection within interlocking.
