Laser (Interlock) Control Systems are a method of ensuring that dangerous (class 3 and 4) lasers are contained. Interlock systems, with proper implementation, will limit the laser access to qualified, trained individuals. The interlock system prevents harm to those who are not properly trained on the safe use and operation of a laser. Laser control systems can range from simple to complex configurations. Here are a few of the basic parts that are needed to get started. 1. ICS-6 Interlock Controller This is the brain of the operation. This versatile unit can control laser interlocks, door locks, illuminated warning signs and other equipment. The ICS-6 can operate beam shutters and laser power with feedback monitoring and fault detection. The controller interfaces with Access Control and Fire Detection Systems. The controller fits to an Override. This allows controlled access through interlocked doors while accepting emergency stop inputs. 2. Access Keypad The access keypad (ICS-KP-14) is used with the ICS-6 interlock controller for the purpose of inhibiting access to a hazardous area by unauthorized persons. The keypad is mounted outside a door which is electronically locked and monitored by the interlock system. It also has two outputs that activate for a set time when the correct 4-digit code is entered: The override output and door unlock output. Each output illuminates a corresponding indication on the keypad when activated. 3. Laser Beam Shutters To prevent damage to eyes or equipment, laser beam shutters are used. To clarify, shutters stop the laser beam automatically during unauthorized access, or manually when the beam is not required. Our shutters are gravity fed for fail-safe operation. Shutters have a remote switching option and are also compatible with safety control systems. 4. Door Interlock Switches Switches monitor the position of the door, window, or access panel (open or closed). You can use them to shut off power, control personnel access, and prevent a laser from starting (or turns it off) when the door is open. 5. Warning Lights Automated switching of single or dual message signs. Frequently used with laser control systems are the LEDS-L-2W and the LEDS-ULT-470-L-2W. These signs run off of 24V and connect directly to the ICS-6 Controller. When the laser is in use, the sign will read in red "Danger Laser On". When the laser is off, the sign will read in green "No Hazard Laser Off". 6. Emergency Stops Emergency stop buttons connect to the ICS-6. Once pushed, this immediately halts the laser in case of emergency. Example of Interlock System Layout In conclusion, those are the basics of a laser control / interlock system.

Laser users should be aware of the risks involved with their equipment. Not all lasers present the same hazards. Proper understanding and training of the particular laser being used, and its dangers, is necessary to avoid injury. Laser with visible beams are categorized into four classes. Class 2 These relatively weak lasers are not a skin or burn hazard. They do not cause eye damage unless someone stares directly at the beam. Class 3R These low powered lasers are not a skin or burn hazard. Laser protective eyewear is generally not necessary. Class 3B These lasers are not a skin or burn hazard. Laser protective eyewear appropriate for the beam's power and wavelength is recommended. Class 4 These lasers can burn skin and cause permanent scarring. some types of material will burn. Laser protective eyewear is essential. Infrared lasers, used commonly in industrial settings, pose invisible risks to the user. The eyes cannot detect infrared, so they must always be protected from exposure. Federal Codes and Regulation (CFR) in the US and IEC codes internationally define laser classes and impost required safety regulations. They mandate manufacturer warning labels and outline specific safety measures for laser operators. American National Standards Institute (ANSI) provides control measures for laser hazards in the US. For example, ANSI Z136.3 provides guidance for the safe use of lasers in health care. ANSI Z136.9 provides standard policies of safe use of lasers in manufacturing environments. EN is the European standard. Certified Laser Safety Officers (CLSO) ensure that compliance with all standards is being met. They can recommend appropriate laser safety eyewear and signage that warns that lasers are in use. Window coverings, such as laser curtains, blinds, or shutters must be in place to prevent laser radiation from escaping through the glass.

All of RT Technologies' LED sign messages are customizable. Choose from our Mini, Ultra, or Slim Jim LED signs and then let us know what messages and or symbols reflect your application. We will send you the proof to approve before the sign is manufactured. Customization fees are extra and this is a one-time charge. If you should happen to need more signs a couple of years from now, no problem; we will not charge you again for the customization. Please contact us for a quote and proof! Here are some examples of recent customizations: For more information on our signs, please contact RT Technologies, inc. at 770-332-0092, or email us at contact@rtlasersafety.com.

High powered lasers are frequently used in industrial applications. Their widest use is in the processing of materials including cutting, drilling, and welding. New applications are being developed all the time. In addition, laser processing can be controlled by computers. Lasers make it possible to effectively cut or drill through materials that are either too brittle or too pliable to be worked with contact tools. Laser welding applications fuse materials together. Higher intensities are generally required to heat and melt the materials. Laser Hazards Lasers must be used to protect against potential hazards to employees. The type of laser, the wavelength at which it operates, and the application being used are factors that determine appropriate safety measures. Exposure to laser radiation can damage eyes and skin. Other laser hazards in the workplace include toxic fumes, chemical spills, and laser produced fires. The occupational safety and health administration (OSHA) publishes specific guidelines for laser usage in the workplace. Laser Safety Laser safety enclosures are required to provide safety in many industrial environments. Controls are required at the entryway to the laser controlled area. Interlocks and protective housings must cover the equipment or the path of the beam. Barriers and curtains must be designed to withstand the intensity of the laser beam. RT Technologies Laser Safety Enclosures RTT provides laser containment systems for industrial users. Tabletop enclosures, assembly line configurations, and room size robotic laser enclosures are available. They provide UV, near infra-red, far infra-red, and visible light protection. All our laser containment systems can be outfitted with laser interlock systems to ensure safe personnel access via enclosure doors, windows, and equipment hatches. Optional closed circuit monitoring systems are available. Design, manufacturing, and installation of our enclosures are supervised by a Staff Certified Laser Safety Officer (CLSO). Our products are FDA/CHRH certified to ANSI and EN specifications.

The audio alert system is a local public address system that audibly delivers a pre-programmed message when triggered. The message is heard from a speaker integrated into the compact unit, which is triggered - either by switching the unit on (by applying 24 VDC), or by movement being detected by a passive infrared detector built into the unit. The audible warning device is contained in a professionally styled, attractive wall mounted unit, and can act as a local public address PA system where it can do the job of an announcer of audible warning messages, providing an acoustic warning to complement visual warning signs. The provision of a talking message enables the loudspeaker feature to be incorporated into hospitals, offices, engineering establishments, doctors or dentists waiting rooms, or other internal environments where audible information is required. The speaking message can be up to 40 seconds long and can be set to automatically repeat as frequently or infrequently as required up to an hour. Institutions or businesses can use the automatic audio alert system as a sound generator to deliver an audible message. There is no need for a loudhailer or megaphone to audibly warn local personnel of dangers in the vicinity. Used as an audible information system - or local audio system - to enable messages, adverts, or audio messages to be delivered when required, this mini announcer, or automatic annunciator, is triggered either by power-up (24 VDC) or by movement picked up by the integrated passive infrared detector, PIR. Program your OWN voice and message with our microphone (sold separately).
