Is the DoorMaster safe as an opener with photoelectric sensors or an external edge sensor?

It is safer. The Door Sensor system provides the obstruction sensitivity of an external edge sensor with the advantage of being able to sense contact with any point on a moving door. Photoelectric sensors provide only a very small zone of door travel, are susceptible to improper installation and sensitive to misalignment.
