Notes:
- 1. Do not scale drawing.
- 2. Total projection 3-5/8" (92mm). (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 assembly to earth ground per state and local electrical regulations.
- 4. See step 1 of 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" (4328mm) 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.
