• Terminals feature self-lifting washers
• Captured screws with
combination heads
• Angled terminals for easy
installation
• Wide gap models available
• Mounting hardware included
The Sentrol 1285T Series surface mount magnetic
contact is ideal for residential and commercial
applications where terminal connects are preferred.
The unit features Sems style terminals that have selflifting washers and captured screws to prevent the
screws from backing out. The screws have combination
heads that accept either Phillips or flat blade drivers.
The terminals are angled away from the mounting
surface to allow for quick and easy installation. Snap-on
covers conceal the terminals and mounting screws for a
clean professional appearance. Wide gap, SPDT, and
high security models are available.

1285T Series Surface Mount Magnetic Contacts Screw Terminals
Architects and Engineering Specifications
The 1285T Series contact shall be a magnetic reed contact
switch. Lead connection to contact shall be through No. 6
screw terminals angled 45° to provide easy access. A plastic
cover shall be provided to protect the screw terminals and to
discourage tampering. The contact shall be 2.54" (6.51 cm)
W x 0.545" (1.39 cm) L x 0.690" (1.77 cm) D. The magnet
shall be 1.74" (4.45 cm) L x 0.595" (1.52 cm) W x 0.545"
(1.39 cm) D. Mounting holes shall be on 2.094" (5.33 cm)
centers. Lock-pin spacers shall be provided that lock into the
base of the contact and magnet, and which lock together to
raise the contact or magnet from the surface for optimal
alignment. Color shall be natural or mahogany brown.

Select desired mounting positions for contact and magnet.
IMPORTANT: Align contact and magnet as directed on
magnet base (switches are polarity sensitive). Attach
contact and magnet to surface. Wire leads to terminals.
Snap on cover.

Mount contact in desired location. Attach ohmmeter to
“closed” loop and “common” terminals. Meter should read
INFINITY with magnet away from contact. Match up contact
and magnet alignment arrows. Bring magnet toward contact
until meter reads 0 ohms. Mark this point and continue
bringing magnet towards contact until meter again reads
INFINITY. Mark this point, and position the magnet between
these two marks. With magnet positioned correctly, contact
shall have balanced operation and will be more difficult to
defeat if an external magnet is used in such an attempt.
