Magnetic Switches (Figures 9.1-9.2; GRI 29
Series
) are used on doors where alarm activation
is not desired unless the door is opened when a
Tag is in the Tx Activation Field.
Positioning the Magnetic Switch
Magnetic Switches are usually located at the top
of the monitored door on the doorstop. The part
that contains the Switch is mounted on the
header or doorframe, while the part that contains
the activating Magnet is mounted on the door
itself (
see Figure 9.3). A recessed model is also
available.

Power Requirements
No power required;
dry contacts rated for 175V DC
For simplicity, in this manual the term
“Magnetic Switch” will reference the entire
Switch as a unit, not just the parts that contain
the contacts.
Temperature
Magnetic Switches operate best in an ambient
temperature between 35 and 90 degrees
Fahrenheit. Operation outside of this range may
cause unexpected or undesirable results,
including premature failure.
Position the Magnetic Switch so that it is nearest
the latch side of the door. If a Magnetic Lock is
used, mount the Switch closest to the latch side
and then the Lock immediately after it.
