Identifying entry system versionsLinear’s AM3, AE-1000, & AE-2000 entry systems have been manufactured in two versions, the “legacy” models and the “plus” models. Units manufactured now are all “plus” models.

In complete units, the models can be easily identified by the model label on the unit. The model label shows the unit’s model number and the unit’s product number.
