Notes:

  • Do not scale drawing.
  • 2. Total projection 3-3/4". (Includes electromagnet and armature assembly.)
  • 3. Non-tri voltage magnets have two non-polarized wires to be connected. Tri voltage magnets are connected using a terminal strip on back of magnet. One wire in common and one wire in the appropriate voltage terminal (non-polarized). Ground surface adapter housing to earth ground per state and local electrical regulations using conductor provided.
  • 4. See Step 1 on sheet 2 for Electric Box location. Anchor Electric Box to withstand a minimum 50 lb. Pull. Electric Box shown installed in a vertical position.
  • 5. Door closing mechanism should have a 3 lb. Closing force at the degree of door opening where door armature and electromagnet engage.
  • 6. Mounting of Electric Box should be reinforced to withstand shock of door opening. Failure to do so will cause box anchors to work loose.
  • 7. All dimensions given in inches (mm).
  • 8. See sheet 2 for more details.

1. Use table to locate Electric Box.

2. Determine door width (Dim "B"). Measure pivot centerline to wall (Dim. "A"). Find dimension "C" in table.

Example: Pivot centerline to wall ("A") = 10" (254mm)

Door Width ("B") = 36" (914mm)

Electric Box Centerline ("C") = 33" (838mm)

3. If "A" or "B" falls between the numbers listed in table, allow for difference.

Example: Pivot centerline to wall ("A") = 17" (432mm)

Door Width ("B") = 36" (914mm)

Electric Box Centerline ("C") = 30-1/4" (768mm)

  • 4. If dimensions "A" and "B" intersect in shaded area of table DO NOT INSTALL ELECTRIC BOX. The degree of door opening will not permit proper alignment between armature and wall magnet.
  • 5. Height to be determined by others. Suggested height is 2' to 4' (610mm to 1219mm) from floor and/or not over 6' (1829mm).
  • 6. Check degree of door opening in table and coordinate with door closers and other door hardware.
