Alarm Contacts
GEORGE RISK INDUSTRIES, INC RECESSED CONTACT,3/8" WIDE GAP
GRI’s recessed switches are most versatile for a variety of applications, but the switch and magnet installed, should never form a “T” configuration. When the application calls for a wide gap switch, using a bare magnet, keep in mind that GRI’s bare magnets are installed with the painted end towards the switch as they are polarity sensitive. When protecting steel doors, use the GRI PA-75 collars with our wide gap switch.
ARMORED WG NO/NC SPDT MAG CONTACT 3" GAP
The Seco-Larm 4601-L3Q is an industrial wide-gap magnetic contact switch with a 3” gap and normally-open & normally-closed contacts.
ANTI-DEFEAT BALANCED CONTACT
The BMC-33B Anti-Defeat Magnetic Contacts are uniquely designed and constructed to make defeating almost impossible. The switch housing contains specially arranged reed switches. These reed switches are pre-set in a biased format with ring magnets, producing a symmetrical magnetic field. The magnetic layout is designed with a combination of three polarized magnets. This switch and magnetic combination produces a perfect symmetrical magnetic field in a balanced condition, as if no magnet field existed. Any attempt to bypass or defeat the BMC-33B with an external magnet will cause the magnetic fields to be imbalanced, thus causing an alarm condition.
