Notes:
- 1. Do not scale drawing.
- 2. Total projection 1-1/8" (29mm). (Includes Electromagnet, Armature Assembly and Wall Cover plate.)
- 3. Power requirements: 12VAC, 24VAC, 24VDC, 120VAC, 240VAC.
- 4. See step 1 of sheet 2 for Single Gang Electric Box location. Anchor Electric Box to withstand a minimum 50 lb. pull. Electric Box shown installed in vertical position.
- 5. IMPORTANT: Check line voltage against voltage specifications on back side of magnet
- assembly before installation.
- 6. Door closing mechanism should have a 3 lb. closing force at the degree of door opening where door armature and electromagnet engage.
- 7. Mounting of Electric Box should be reinforced to withstand shock of door opening. Failure to do so will cause box anchors to work loose.
- 8. All dimensions given in inches (mm).
- 9. See sheet 2 for more details.

STEP 1 – Location of Electric Box
- 1. To locate Electric Box use table below.
- 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" (25.4cm)
Door Width ("B") = 36" (91.4cm)
Electric Box Centerline ("C") = 33" (83.8cm)
3. If "A" or "B" falls between the numbers listed in table allow for difference.
Example:
Pivot centerline to wall ("A") = 7" (17.8cm)
Door Width ("B") = 36" (91.4cm)
Electric Box Centerline ("C") = 33-5/8" (85.4cm)
- 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 not over 6'0" (1.8m).
- 6. Check degree of door opening in table and coordinate with door closers and other door hardware.
- 7. Total projection of door hardware must not project more than 1-5/8" (41.3mm) on pull side of door.
