MSS Standard
Series Product Sheet
Security Contacts have been made with a
decades-old technology called the Reed switch.
Reed switches have three inherent weaknesses
when used in security contacts. They are (1)
Easily defeated with magnets, (2) Prone to
permanent contact weld failure (from lightning
and power surges), and (3) fragile (made mostly
of glass, they are subject to damage even when
packaged as security contacts).
The MAGNASPHERE line of security sensors
provides a solution to all of these issues.
Utilizing the the patented, revolutionary
MAGNASPHERE
products virtually unbreakable, and highly
resistant to permanent contact welding and
outsider magnet defeat, allowing
MAGNASPHERE to offer a lifetime replacement
warranty.

MSS contacts are available in both the
traditional Closed Loop (contact closed when
magnet is present) as well as the more Secure
Open Loop (contact open when magnet is
present) electrical configuration. This is the
same configuration required for other life safety
devices such as smoke and fire alarms, and has
long been the recommend configuration by
most knowledgeable security professionals.

Reed contacts operate on magnetic fields.
Most contacts are Closed in the secure
position (Closed Loop) when the door is
closed and the magnet is near the switch.
Reed switch contacts are globally magnetic:
they will respond to the strongest magnetic
field anywhere around the contact –– not
solely to the door magnet. When compromised,
reed contacts will still send secure signals.
