Security+®

The MT is equipped with a Security+ rolling code receiver. With every activation, Security+® transmits a brand-new code, one of over 100-billion codes, never to be repeated.

CPS® Commercial protector system®

CPS‑U photo eyes are shipped with unit. They project an invisible light beam across the garage door opening and automatically reverse the door if anything interrupts the beam while the door is going down. Sensing technology will stop the door from closing if contact is made with a person or object. Alternate entrapment protection devices may be used or added, such as light curtains and optical edge systems.
