Model 2870 Accessory, Armature Swivel Extension
DynaLock 2800 Series Electromagnetic Door Holders are designed to hold self-closing fire or smoke barrier doors open until automatically released by fire alarm, smoke detection, or sprinkler systems. They can also be manually controlled wherever instant closing of doors is required for safety or convenience. Each door holder assembly consists of a floor or wall mounted heavy-duty electromagnet, a selfadjusting and pivoting armature, and all necessary mounting hardware. All models are field selectable to operate on 12 VDC, 24 VAC/VDC, or 120 VAC input voltage. Convenient screw terminals are provided for field hook-up. All holder models are UL listed. Optional Extension rods are available, to extend the armature projection, for installations where a wide standoff distance between the electromagnet and armature mounting locations exist. DynaLock 2800 Door Holders each provide 30-45 lbs. of holding force, allowing manual door closure when electromagnets are energized.
