Automatic Doors For Pedestrian and Industrial Applications

Automatic Doors For Pedestrian and Industrial Applications A Guide to Automatic Doors, Door Control Sensors, & Door Control Switches Plus The Technology That Makes Some Doors Safer Than Others

At MS SEDCO we open important doors safely We began opening doors at 1600 Pennsylvania Avenue N.W., more than 10 years ago. And we were opening other important doors across the country and around the world 23 years before that. During our many years in this business we ve learned a great deal sometimes the hard way about automatic doors. We ve summarized our knowledge in this Guide and we hope it will prove helpful to you as you determine the best and safest way to open your important doors. Automatic Doors The Benefits We can think of no other single investment that can provide the wide range of benefits offered by an automatic door. In Pedestrian Applications, automatic doors can: Increase sales by improving attractiveness of the store front and providing the store with an up-scale image. Send this subtle but clear message to customers: You are important. Increase customer convenience which creates happier shoppers. Everyone appreciates automatic doors especially pedestrians who may be pushing a baby stroller or grocery cart, may be carrying packages or a child, or may be using crutches, a walker, or wheelchair. Increase safety by minimizing doorway congestion and providing hands-free door activation. Simplify and lower the cost of compliance with the Americans with Disabilities Act (ADA). During new construction or remodeling, it is often less costly to provide barrier-free access via an automatic door than it is to comply with government-mandated architectural requirements. In Industrial Applications, automatic doors can: Increase safety by reducing traffic congestion and preventing employees and/or visitors from injuring themselves while lifting heavy overhead doors. Increase the comfort of employees, customers, and visitors. In many instances, large industrial doors are left wide open to make it easy for trucks, fork lifts, and other vehicles to enter and exit the facilities. These wide-open doors permit the entrance of outside air that often makes conditions inside the building intolerable and even unsafe. An automatic door makes it feasible for doors to remain closed except when passage through the door is desired. Increase worker productivity. Nearly every company that has performed a time & motion study has been surprised at the amount of time certain workers, forklift operators for example, waste manually opening and closing doors during a normal workday. It is not uncommon for the installation of an automatic door to add as much as one hour or more to the productive time of certain workers. The bottom line: an automatic door in pedestrian applications can decrease certain costs and increase convenience and safety plus (in retail environments) lead to increased sales. The bottom line: an automatic door in industrial applications can reduce injuries, provide for increased comfort, and significantly increase both worker productivity and corporate profits. 2 AUTOMATIC DOORS

Back Cover Product Line Summary.................. Back Cover Member: AAADM Association of American Automatic Door Manufacturers Automatic Doors How They Work To operate properly, every automatic door requires a Door Control System that can sense certain conditions in and near the doorway. In the majority of today s applications, the sensing tasks are performed by various combinations of three devices: (1) motion detectors, (2) presence detectors, and (3) safety beams. The function of each of these devices is described below. (Note: special rubber switch mats have been used to detect presence however, such mats are used infrequently due to their unsightly appearance and high maintenance/installation costs.) There are five types of automatic doors: swinging, sliding, folding, revolving, and overhead (illustrated on back cover). Figures 3-1 through 3-3 below indicate the basic function of each door control sensing device in a typical swinging door application. Although there are nearly an infinite number of ways that various combinations of sensors can be used to control the five types of doors, if you are familiar with the basic purpose of each device as described below you will have sufficient knowledge to understand the many different applications of door sensors. Motion Detectors (Approach) Motion detectors (microwave or infrared) are used to determine a person or object has entered the Activation Zone. Once motion is detected, an open command is sent to the door which then automatically opens to permit passage through the doorway. Presence Detectors (Safety) Presence detectors (microwave or infrared technology) are used to watch a given area to decide if, due to safety concerns, there are any reasons the door should not be opened, should be kept open, or (in the case of sliding doors) should have door movement reversed. Safety Beams Safety Beams (infrared technology) are used as specific location presence detectors. They, too, determine if, due to safety concerns, there are any reasons the door should not be opened, should be kept open, or (in the case of sliding doors) should have door movement reversed. Safe Zone is clear. Door opens when pedestrian enters Activation Zone. Door swings away from pedestrian Object sensed in Safe Zone. Door will not open. Object sensed in Beam Path.

Automatic Door Control Sensors What to Look For When selecting an automatic door control system, safety is paramount Not all sensing devices are created equal; newest technologies make some devices safer than others Many changes have taken place in the automatic door industry through the years but none impact safety more than recent changes in Microwave Motion and Infrared Detection technologies. These new technologies have improved safety and created new industry rules virtually overnight. An understanding of these recent technological changes is critically important because adherence to the old beliefs can compromise the safety of those passing through automatic doors. Motion Detection: Human Presence Radar (HPR) changed the rules Presence Detection: Floor Reflection Method and Maximum Pattern Infrared changed the rules If presented with the following Motion Detection True/False Test, many in the door industry might respond True to each question. In each case they would be wrong. The correct answers are indicated by the checkmarked boxes. 1. True or False: All microwave motion detectors are alike and operate pretty much the same. True False 2. True or False: Microwave motion detectors are useful only to open a door and cannot provide safety. True False 3. True or False: Microwave motion detectors cannot sense human presence unless rapid and significant movement is occurring in the activation zone. True False The answers to the above questions were True prior to a breakthrough in microwave technology and the introduction of Human Presence Radar (HPR ) from MS SEDCO. Unlike other microwave motion detectors, Human Presence Radar detectors are able to sense the presence of a human standing or moving extremely slowly in the Activation Zone and thus add a level of safety to any automatic door application. See facing page for additional HPR information. If presented with the following Presence Detection True/False Test, many in the door industry might respond True to each question. In each case they would be wrong. The correct answers are indicated by the checkmarked boxes. 1. True or False: All types of infrared presence detectors operate similarly and provide the same amount of safety. True False 2. True or False: All active infrared presence detectors operate similarly and provide the same amount of safety. True False 3. True or False: All types of active reflective and lens-focused infrared detectors operate similarly and provide the same amount of safety. True False Infrared light can be used in a variety of very different ways to detect presence and for that reason it is not surprising that many would answer the above questions incorrectly. Today it is widely accepted that the best performing and safest of the infrared technologies utilize both Floor Reflection Method Active Infrared (FRM-AI or simply FRM ) and a maximum number of beam patterns (Maximum Pattern Infrared or MPI ). See facing page for additional FRM and MPI information. Human Presence Radar (HPR ) detectors provide more safety than any other standalone microwave motion detector. Floor Reflection Method (FRM ) detectors with Maximum Pattern Infrared (MPI ) provide more safety than any other infrared detector. You can upgrade to HPR and MPI at no additional cost. But you ll have to ask. Human Presence Radar (HPR ) and Maximum Pattern Infrared (MPI ) have added a level of door safety previously unattainable without increasing cost. These newest technologies, however, are not yet included in many standard pre-packaged door control systems. So if you want the maximum safety for your application, be sure to specify Human Presence Radar and Maximum Pattern Infrared when placing orders. 4 SENSORS

New Door Control Technologies Improve Safety Human Presence Radar HPR The safest motion detector: SafePath D38 with Human Presence Radar (HPR ) The SafePath D38 with Human Presence Radar (HPR) is the only standalone microwave motion detector that provides protection for a person who has entered the door Activation Zone and then stops or slows to an extremely slow pace. (Such an unpredictable movement pattern is common amongst the elderly and/or persons using a walker, crutches, or wheelchair and perhaps even someone pushing a baby stroller.) With any standalone microwave motion detector except the SafePath D38, if a pedestrian stops and dwells in the Activation Zone, the door which opened when the person entered the Zone will begin to close. This unexpected and unwanted door movement is likely to startle the pedestrian and could cause the pedestrian to react by panicking, falling, and sustaining injury. Some door control manufacturers attempt to provide protection for elderly or slow-moving pedestrians by changing detection directionality in the Activation Zone and/or installing sensors on the door that will stop the unwanted door movement when the door is just six inches from the pedestrian. These systems lack effectiveness and increase the potential for injury because they do not eliminate the startle factor. Merely switching the detection logic in order to permit the system to sense a pedestrian that has entered the Activation Zone and then reversed his/her course 180 provides no extra safety whatsoever if that individual either stops or is moving very slowly regardless of the direction of the movement. Similarly, halting the movement of the door just a few inches before it strikes the pedestrian is of much less value than it at first may appear. The problem is that pedestrians in the doorway do not know that the door will stop just a few inches before striking them and therefore they are likely to react to the unwanted door movement towards them by becoming startled, by panicking, and by falling. Competitive Safety Comparison: Microwave Motion Detectors Standard Safety Test After being activated by normal motion, detector has capability of preventing startle factor by holding door open even if a pedestrian in Activation Zone slows down or stops. Non-HPR Detectors FAILS Unsafe Potential Startle Danger SafePath D38 with HPR PASSES Safe Uses HPR Note: With any system, it is possible to alter performance by adding sensors (and cost). The test results shown above are representative of single microwave motion detectors in standalone applications. Table 5-1 Maximum Pattern Infrared MPI The safest presence detector: SafePath Floor Reflection Method Active Infrared (FRM-AI ) with (MPI ) Several types of infrared systems have been used as presence detectors including (1) passive infrared systems, (2) diffuse scan active infrared systems, and (3) active infrared reflective scan systems. Common weaknesses of some infrared presence detection systems include poor reaction times, differing responses to colors, adverse reactions to direct sunlight, and failure to sense very short objects plus can be very difficult to tune during installation. The safest infrared technology and how it works Floor Reflection Method Active Infrared technology (FRM-AI or simply FRM) overcomes or minimizes the effects of each of the performance-limiting weaknesses listed above. As a result, FRM is widely accepted today as the best performing and safest of all infrared sensing technologies. In FRM systems, infrared beams are directed from an above-the-door sensor towards the floor. The beams reach the floor and are then reflected back from the floor to the sensor. Systems in which beams do not reach all of the way to the floor suffer from several limitations and do not provide the same degree of protection as an FRM system. See Figures 5-1 and 5-2. Beam coverage: Non-FRM system Hazardous Figure 5-1 Figure 5-2 In Figure 5-1, a hazardous condition occurs because the infrared pattern does not sense the child s wagon. In Figure 5-2, the beams from the FRM system reach all of the way to the floor and therefore the wagon is sensed. Maximum Pattern Infrared (MPI) All FRM sensors use similar technologies. An important difference between devices, however, exists in the number of discrete beams that are used in the sensing patterns. The more beams a system has, the more precisely and safely the system can sense an object in the Safe Zone. See Figures 5-3 and 5-4. Beam pattern: Non-MPI Figure 5-3 Safe Beam pattern: SafePath with MPI Figure 5-4 Beam coverage: FRM system Hazard: Object not detected Sparse pattern can cause poor performance. Object is detected MPI offers the most dense and safest pattern. The best way to avoid the startle factor and prevent accidents is to keep the door open while the pedestrian is in the Activation Zone. The only standalone microwave motion detector with the ability to do that is the D38. SafePath Maximum Pattern Infrared (MPI) sensors use approximately twice as many beams as other manufacturers and provide a level of safety not found in any other standalone infrared detection device.

MS SEDCO Door Control Switches for Wired and Wireless (Radio Control) Applications Introducing the best way ever to open a door with a switch: ClearPath Radio Control Switches The Benefits of Radio Control Switches Eliminate time-consuming wire pulling. Significantly reduce installation costs especially in those applications that require extensive labor to drill holes in concrete, masonry, or heavy steel. Can be installed in a fraction of the time required for wired switch applications. Ideal in applications requiring long runs of cable that would be unsightly and vulnerable to vandals. Ideal where appearance is critical such as in Historical Preservation Projects. 8 SWITCHES Typical Radio Control Switch Operation Figure 8-1

ClearPath Radio Control Switches with HDRC solve problems caused by interference and stray signals and are guaranteed to work where others won t Radio Control Switch performance Problems at 433 MHz and other frequencies Figure 9-1 Systems without ClearPath and HDRC Most radio control switch systems being sold today perform poorly in many applications due to the susceptibility of systems to stray signals and radio frequency interference (RFI). To complicate matters, problems caused by stray signals and RFI are usually intermittent and elusive. So even if there appear to be no problems with a non-clearpath system at the time it is installed, there is no guarantee that a problem will not occur just one hour after you thought the installation was successfully completed. Switches operating at frequencies near the 433 to 435 MHz band are particularly prone to problems because amateur (ham) radio operators transmit high-power signals in that band which easily overpower the weaker 433 MHz signals. Any 433 MHz door switch may encounter unexpected and unrepeatable problems that technicians unfamiliar with amateur radio will most likely never solve. ClearPath Solutions: HDRC, three separate frequencies, and industry-wide compatibility ClearPath Radio Control Switches were developed specifically to overcome problems caused by stray signals and RFI. Every ClearPath product utilizes HDRC (High Definition Radio Control) that employs sophisticated electronic circuitry and SAW Figure 9-2 Systems with ClearPath and HDRC components to block stray signals and permit transmitted signals to cut through signal-distorting RFI. ClearPath switches are the only products available that operate on any of three user-selectable frequencies: 300 MHz, 390 MHz, and HDRC. ClearPath products also feature SignalLock a unique feature that insures all open-the-door signals are transmitted for the maximum allowable FCC time, even if the radio control door switch is only momentarily tapped. MS SEDCO ClearPath products can meet all of your radio control switch needs: Single-door operation (CP/TX Series) Sequential two-door operation for vestibule applications (CP/STX Series) Dual transmitters for individual activation of two separate doors (CP/TX-V Series) Portable, handheld transmitters (CP/TX-HH Series) Four-mode receivers: Single channel, dual channel, adjustable time delay, and dual sequenced outputs. With options, receiver can sequence electric locks without additional timers or relays. (CP/RX Series) See ClearPath data sheets for complete description of product functionality and detailed specifications Examples of ClearPath Faceplates See pages 10 and 11 for a complete listing ClearPath products are FCC licensed, comply with all HDRC requirements, and are compatible with previous MS SEDCO devices as well as with the products of many other manufacturers. ClearPath: How it works RF signal Switch is pressed, but RFI prevents door from opening Stray signals in non-clearpath system can mistakenly open door ClearPath RF signal ClearPath HDRC cuts through interference and door opens Stray signals are blocked by HDRC and do not mistakenly open door Figure 9-3 SWITCHES 9
