7 SENSORS Ultima X Series Gas Monitors 5 State-of-the-art detection for any gas need Ultima X Series Gas Monitors feature the latest mechanical and electrical technologies to monitor against the threat of combustible and toxic gases and for oxygen deficiency. Installation is simple and flexible, and calibration is easy. Features Patented sensor disconnect under power allows for sensor change-out without declassifying a hazardous area. Interchangeable smart sensors can be replaced in the field without the use of tools. The unit quickly recognizes the new sensor type and reconfigures alarm and relay settings to optimize the new sensor. State-of-the-art liquid crystal display conveniently alternates between sensor reading and gas type and features scrolling messaging, indicating ongoing diagnostic checks such as sensor "end-of-life" condition. World-class design features a singleboard design for ultimate reliability and serviceability. The multiple-entry mounting enclosure has been designed to be separate from the electronics and sensor, allowing for problem-free installation and servicing. Onboard optional quick-check LEDs and 4 relay outputs allow for increased indication of alarm and fault conditions.

19 SENSORS Chillgard RT Photoacoustic Infrared Refrigerant Monitor 5 The industry stadard for refrigerant leak detection monitors The Chillgard RT Photoacoustic Infrared Refrigerant Monitor provides economical, lowlevel monitoring of refrigerant gases used in most refriger-ation systems or chillers. By detecting leaks early enough to prevent a major loss of refrigerant gas, the monitor reduces operating costs. Chillagrd RT Monitors meet the requirements of ANSI/ASHRAE Sensor Technology The Chillgard RT Monitor utilizes very stable and highly selective photoacoustic infrared (IR) technology to sense refrigerant gases at levels as low as 1 part-per million. Can operate for months with virtually no zero drift Inherent stability eliminates the need for autozeroing techniques that take the monitor off-line at regular intervals, leaving the area unprotected Fresh air sampling line or on-line scrubber is not required High immunity to interferents such as cleaning agents and solvents Unaffected by changes in humidity Operates over a wide temperature range Detects single or multiple refrigerants Expandability Simply by adding the Multipoint Sequencer, the Chillgard RT Refrigerant Monitor can be expanded to monitor up to 8 locations, resulting in: More cost-effective monitoring, especially when monitoring large areas or multiple locations or chillers The fastest possible response to any leak or spill Fresh sample pumped from locations up to 500 feet for each sample Simplicity/ Ease of Use Easy to install, operate and maintain.

38 MSA FLAME DETECTORS MSA FLAME DETECTORS

39 FLAME FlameGard Series of Flame Detectors 5 Fast, reliable optical flame detection for hydrocarbon-based fires MSA FlameGard Flame Detectors provide constant monitoring for fire or flame by detecting the characteristic ultraviolet (UV) and/or infrared (IR) radiation from a hydrogen or hydrocarbon-fueled fire. They operate as a stand alone unit without a control panel, or can be connected to a fire or security panel via an internal alarm or accessory relay. FlameGard Detectors reduce the possibility of false alarms because the units must receive the proper wavelength, duration and intensity of the fire s radiation before an alarm is activated. 3 Versions: FlameGard UV Flame Detector: monitors UV radiation FlameGard UV/IR Flame Detector: dual-optical sensing monitors UV and IR radiation FlameGard IR3 Flame Detector: patented triple-ir technique monitors IR radiation with enhanced immunity to false alarms Simplicity/ Ease of Use Easy to operate and maintain Easily mounted via a simple bracket or the optional Swivel Mount Kit High-speed response with false alarm suppression 4 to 20mA and RS-485 outputs Alarm, accessory and fault relays Manual or automatic built-in test feature performs a complete functional test as desired, or routinely during operation Optional MSA Fire Simulator provides flame-free testing Flexibility Stand alone operation or connection to standard four wire fire control panels User programmable to various configurations Durability Enclosed in heavy-duty, copper-free, explosion-proof aluminum or stainless steel housings FlameGard IR3 Detector Uses a patented triple-infrared (IR) detection technique that offers two to three times the detection distance (up to 200 ft) of conventional IR or UV/IR detectors. This technique uses the signal from 3 different sensors, each looking at a different infrared frequency. All the signals are checked for the proper ratio and relationship to each other before an alarm is given. This enhances immunity to false alarms, though not at the expense of sensitivity to a real fire or flame condition. [Datasheet ] 40 MSA Customer Service MSA-INST
