Pulsar Garage-Door Opener Remotes are ideal for commercial and residential gate and Garage Door Controls. Pulsar has been controlling commercial, industrial and residential overhead doors and gates for more than 40 years. The Pulsar radios in the North Shore Commercial Door Pulsar catalogue are not original equipment. These are functionally equivalent to the originals, transmitting and receiving on 318 MHz. An updated style case has replaced the original. All programming is the same, and they will work interchangeably with the previous equipment.
