MAGNASPHERE security sensors' magnet
ball contact is open in the secure position
(Open Loop) when the door is closed and
the door magnet is near the switch.
MAGNASPHERE Security Sensors are Open
Loop and highly resistant to contact welding
from power surges and lightning strikes.
A defeat magnet
introduced OUTSIDE
the door will have no
effect on the ball
contact. When the
door is opened, the
contact will close,
and the
SYSTEM
WILL ALARM.
Because the magnet
ball contact will not
weld, when the door
is opened the
contact will close
and the
SYSTEM
WILL ALARM.
MAGNASPHERE’s contact is a spherical
magnet and operates in a defined activation
zone directed toward the door magnet.
The patented, award-winning MAGNASPHERE switch technology was designed as
a security device which over comes the deficiencies of reed contacts.
The MAGNASPHERE
switch is (1)
Resistant to magnetic defeat and tamper,
(2)
Resistant to permanent contact welding
from lightning
and power surges, and (3) Robust, all metal welded construction is
virtually unbreakable.
