Sentex Systems MKMB111611002 Keypad Control Board
 |
Sentex Systems MKMB111611002 is a keypad control board used in telephone entry and gate‑opener access systems. Common failure modes for this class of boards include burned or cracked ICs, damaged power regulator traces, and loose or corroded connector pins due to vibration. First‑check diagnostics: verify the 12 V DC input voltage with a multimeter; inspect all surface‑mount components and solder joints for signs of overheating or mechanical damage; then test the keypad matrix by measuring continuity between key contacts and the board’s I/O lines, followed by reviewing any error codes displayed on the connected access controller.[oss-gpt-20b] |
