How the HSS Magnet / Removal Tamper Circuit Works
The MAGNASPHERE HSS Incorporates the Most
Secure Anti-Tamper Features of Any Device Available.
In addition to the sensors inside that will detect the
presence of a stronger defeat magnet placed on any
surface of the HSS, the removal tamper circuit will
alarm BEFORE the HSS can be removed.
You will notice that the mounting hole on the upper
right face of the HSS sensor is larger than the other
mounting holes and slightly off set towards the center
of the sensor. A tamper proof MAGNASPHERE
switch is positioned inside the unit facing the bore
of this mounting hole.
Whether you use the four mounting holes on the
face of the sensor (in-swinging doors), or the two
mounting holes on the bottom of the sensor (out-
swinging doors), the upper right mounting hole with
the removal tamper switch will be used.
Once the unit has been mounted, the removal
tamper magnet (included) is inserted into this
mounting hole. It will be attracted to the mounting
screw and will activate the removal tamper switch.
The mounting hole cover cap (included) is then
inserted and locked into position.
In order to access that mounting screw to remove
the sensor, the locking cap must be pried out, and
a steel rod or magnet inserted into the hole to
extract the tamper magnet. Removal of the tamper
magnet will cause the removal tamper switch
to alarm.
The HSS also includes anti-rotation pins that will
prevent an intruder from removing the non-removal
tamper mounting screws and twisting the HSS into
a position where another door actuating magnet
could be placed, simulating a secure position.
Unique Cross-Hole Mounting Feature Eliminates Need
A Unique Feature of the MAGNASPHERE HSS is the
Two Mounting Holes Located on the Bottom Surface
of the Sensor that Faces the Actuating Magnet.
Using these mounting holes allows the installation
of the sensor directly to the door stop, eliminating
the need for an L bracket.
The actuation magnet is then mounted directly to
the surface of the door so that it lines up beneath
the door stop mounted sensor, eliminating the need
for a Z bracket.

for L or Z Brackets on Most Out-Swinging Doors
Depending on the “play” in the door to stop fit, it may
be necessary to use a magnet spacer(s) ( available
from MAGNASPHERE ) to insure proper alignment
between sensor and magnet.
On in-swinging doors (flush to frame), the HSS
sensor is mounted directly to the door frame, and the
actuation magnet is mounted directly to the door.
