A trusted product for industrial, commercial, and residential buildings, SL 585 gate operators are known for various features. They come with a pre-motion warning alarm that activates three seconds prior to any gate motion. Not only that but the gate operator has a maximum run timer that protects against any damage to the gate and operator by limiting the unit’s run time to 120 seconds. It has an external alarm reset button, as well as an inherent reversing sensor that detects obstructions and reverses gate when closing or stops/reverses gate when opening. Some other standard features include mechanical limit system, monitored safety input, security+ 2.0 ®, radio receiver, LED diagnostic display, and programmable auxiliary relays. This slide gate operator has been tested to the most stringent UL 325 safety standards. If you require us to supply, install, or repair this product, feel free to call us.
