7700PT Power Track®

The Power Track® Series combines the function of a single-point electromechanical door holder with the proven reliability of a standard 7700 Series door closer.  The track assembly contains an arm slide and solenoid operated hold open mechanism.  Shipped with a track only, the closer is mounted on the door; the track and hook-up box are mounted to the frame face or frame soffit depending on the installation requirements.  The degree of door hold open is selected by adjustment of the telescoping arm. Any power interruption will release the arm slide and the door will close.  The door can be manually released at any time.

Closers for ______ doors shall be electromechanical closer holder. Hold open to be achieved by electric solenoid locking of closer arm slide in its track. Track, arm, slide (and) solenoid to be contained in a single aluminum extrusion 1-1/2" (38mm) high, 1-1/2" (38mm) deep. Closer shall be door mounted. Track and hold open mechanism shall be surface mounted to the frame face for application on the pull side of the door and frame soffit mounted for application on the push side of the door. Single point hold open shall be selective through a range of 85° to 110°. Hold open point to be achieved by adjustment of a telescoping closer arm. Closer shall be hydraulic with full rack and pinion enclosed in a cast aluminum alloy shell. Hydraulic fluid shall be non-gumming and non-freezing. Closer shall have two non-critical valves to independently regulate sweep speed and latch speed. It shall have an adjustable backcheck cushioning valve and an adjustable backcheck positioning valve. All valves shall be adjustable with a hex-key. (Closer shall have spring power adjustment to permit 50% increase in closing power.) Closer to be enclosed in a molded full cover. (Support units to be controlled by U.L. Listed Smoke Detection Equipment.) Units to be fail safe and close the door during an interruption to the electrical power. The hold open solenoid coil shall have a maximum amperage draw of (.090 Amps at 24 volts) (.018 Amps at 120 volts). Unit shall have a switch to permit testing of the releasing device function without alarming the system. All wiring connections shall be made without the need of wire nuts or soldering. Support unit(s) shall require a (24VAC/DC) (120, 60Hz) power input. Supplier to coordinate electrical requirements with electrical and alarm system engineers. Wiring (and conduit) by others. Electromechanical Closer-Holder to be Norton® Power Track® [(P)7700(PTO) (PTDO)].
