The "MTMV 01" is typically part of a modular system, meaning it connects to a riser bus that runs vertically through the building. Unlike simple 2-wire analog systems, BPT often uses a or multiwire configuration.
Locate the power input terminals on the MTMV-01. Connect your DC power supply wires to these terminals, observing polarity (Positive to +, Negative to -). If the unit is polarity-sensitive, there is often a diode protection circuit; ensure you connect it correctly the first time to avoid blowing the internal fuse. bpt mtmv 01 wiring diagram
| Symptom | Likely Wiring Cause | Solution | | :--- | :--- | :--- | | | +V1 and -V1 reversed or loose. | Swap polarity. Check for 12V DC between + and - . | | Can hear visitor but no video | L1 (video) disconnected or M ground missing. | Secure L1 connection. Ensure M is common with power ground. | | Can see video but no audio | L2 (audio bus) is broken or shorted. | Check continuity on L2 wire. Look for shorts to adjacent wires. | | Door release doesn’t work | Wires on A and M are swapped or broken. | Verify button connects A to M . Measure resistance (0 ohms when pressed). | | Interference / Rolling video | Poor M ground. Shield not connected. | Re-terminate M . In shielded cable, connect drain wire only at the main panel. | | Call from entrance fails | Incorrect apartment address DIP switch. | Review main panel programming chart. Address must match riser assignment. | The "MTMV 01" is typically part of a
