Control Switching Using DPDT Switches
This information describes how to achieve dual switching with one magnetic contact and one magnet. Interlogix DPDT magnetic contacts such as the Sentrol 1087D, 1084D, 2507AD, or 2707AD (see catalog) may be used in place of two contacts or one contact and a floor mat for an annunciator panel. Other applications include access control multiplex systems, computer monitoring of doors, lighting control and safety systems. DPDT switches are available in recessed, steel door, surface and industrial outdoor models.
Note: Each switch is electrically and mechanically isolated from the other and may switch at a slightly different point.
