Are the detectors tolerant to misalignment?

Since the transmitted infrared beams are not sharply focused, the detectors are able to tolerate a certain degree of misalignment. The tolerance to misalignment may be measured as the maximum allowable separation between parallel center lines for a given separation. The tolerance to misalignment will be greatest when the detectors are separated by the door opening width e.g. at a separation of 42″ the tolerance to misalignment will be +/- 25″ horizontally! The minimum tolerance to misalignment will be when the detectors are touching surfaces i.e. when the doors are fully closed. In this situation the detectors will tolerate alignment within +/- 0.5″ horizontally and +/- 1″ vertically as indicated in the Pana40 Plus Installation Booklet.
