COMPONENT ID
The Door Mounted Safety Sensor (DMSS) (8310-804) detector is a door-mounted presence detection system that is used on
automatic pedestrian swing doors. Unlike other door-mounted sensing devices, the sensors unique electronic architecture allows
the detection modules to be mounted near the top of the door, out of harm's way. A rotating cam is used for the range adjustment
of the detection zone. Width patterns may be altered by adding slave modules to the master module. These slave modules are
simply added by inserting them into the aluminum extrusion, then connecting them with the attached flat ribbon cable to the next
module without interrupting other modules in the same extrusion. Once installed, the detection zone (in addition to being
adjustable for distance) can be angled independently from the other modules.
Each DMSS module consists of two optics, a transmitter (TX) and a receiver (RX), and functions independently of the other
modules. The transmitter emits an extremely precise beam, which measures approximately 4" in diameter at a distance of 8'.
The receiver, in turn, receives the infrared beam reflected off of the floor. This transmission and reception forms a detection
triangle, which is the basic premise of detection (called triangulation). Should this angle be interrupted, detection will occur.
Detection is NOT based upon the intensity of the beam, and in principle will not be affected by the color or background of the
object that interrupts the angle.
