Magnetic Contacts

Installation Instructions

1045, 1045W

Select desired mounting positions for contact and magnet. Align labels on contact
and magnet so labels read in the same direction.

1047H

Mount contact in desired location. Attach ohmmeter to "Closed Loop" and
"Common" terminals. Meter should read INFINITY with magnet away from contact.
Align labels on contact and magnet so labels read in the same direction (switch is
polarity sensitive). Bring magnet toward contact until meter reads 0 ohms. Mark this
point and continue bringing magnet toward contact until meter again reads
INFINITY . Mark this point and position the magnet between these two marks. With
magnet positioned correctly, the contact shall have a balanced operation and will be
more difficult to defeat if an external magnet is used in such an attempt.
