New electronic security products come to the market to address end users’ needs. One example is the threat posed by infection and communicable diseases. Sometimes they are used as weapons. Sometimes they are the consequence of poor hygiene and dense population. In some cases, such as healthcare facilities and schools, the occupancy of the premises is simply more prone to infectious and communicable disease.
Lines of defense against these diseases include antimicrobial sprays and hand washing dispensers, anti-microbial coatings applied to door hardware, and devices which make it unnecessary to touch door hardware in order to enter or exit.
Door operators are an example of a device which offers this functionality. Although full power door operators such as those used for supermarkets are automatic, low energy operators utilize devices referred to as knowing act switches to trigger the opening of the door. Traditionally these devices were switch plates that persons press when approaching the entrance.
A new class of knowing act switches is now available which do not require that the hand to come into physical contact with it. Therefore people can transgress the opening without ever actually touching the switch or the door, eliminating the possibility of depositing or acquiring a infectious or communicable disease due to contact.
We start our review of new electronic products with this category.
BEA Touchless Switches
BEA’s microwave motion sensor is used as a contact-free switch, providing excellent control and operation of automatic doors. Doppler Radar technology allows for use in sterile environments such as clean-rooms, healthcare facilities and food processing plants.
It can be placed unobtrusively in a room or hallway when mounted behind a non-reflective surface where the aesthetics demand it be inconspicuous. Variable adjustment of pattern depth ranges from 4 to 24 inches.
No wearing parts mean increased product life. Water-resistant foam gasket provides increased durability when product is exposed to water or cleaning product
The MS-09 (PN:10MS09TL, 10MS09L) is an IP-65 rated version of BEA’s MS-08, a touchless switch that operates on the Doppler effect principle. A microwave signal is emitted from the sensor. When this signal is reflected from a target, the signal is compared to the original signal. If the target is moving, the frequency of the reflected signal is different from the emitted signal. This difference in frequency is processed and sends a signal to the door to open.
This switch provides excellent control of door operation for industrial doors by reducing energy costs. It also provides door control in sterile environments and has a sleek profile to limit dust collection. The MS-09 may be mounted behind various non-reflective materials such as plastic, wood, and glass. However, the thickness of any material put in front of the switch may affect the operation of the detector. Reflective materials such as metal will prevent the detector from working. The MS-09 has adjustments that allow the range of detection to be varied from 2 to 24” and relay hold time of the door to be varied from 1 to 10 seconds.
Viking Bluetooth Door Controller
The demand for hands-free access control is also on the rise. Hands-free solutions make it unnecessary for the person seeking access to touch a reader or keypad. These devices also provide for a greater throughput, and the devices are less intrusive and therefore more immune to vandalism. One new device from Viking harnesses the power of Bluetooth and the popularity of smartphones to enable standalone hands free credential-less access control.
The Viking BTC-1 allows a user to actuate a door strike or door controller by touching an icon on their Bluetooth-enabled Android phone or tablet. The BTC-1 can be pre-programmed with the type of contact needed, NO or NC, and the duration of the contact from 0.5 to 120 seconds. Continuous on is also supported (see current limits below).
This self-contained unit is attractive, discreet, easy to install, and is less a target for vandals than a separate camera and enclosure would present.
