Multi criteria detector

Multi-criteria detectors are used when more than one element need to be monitored by a detector. Wireless detectors are also available that make installation easier and quicker. The PTIR detector is an intelligent, multi-criteria detector incorporating photoelectric, thermal and infrared detection principles to sense a wider range of fires with greater accuracy. Advanced algorithms maximize the advantages of each sensor type creating a more robust detection strategy that rejects nuisance sources but still responds quickly to real fires. This is appropriate because local municipalities are enforcing strict false alarm regulations that include fines.

This advanced multi-criteria detector normally operates at a high immunity level and changes to become very sensitive to fires as soon as fire characteristics are sensed. In this way, nuisances are monitored and ignore reducing false alarms. From clean rooms to industrial installations, the six sensitivity levels meet any need for early, accurate detection with confirmation of a true fire condition before alarming. The FWD-200P is a wireless Photoelectric smoke detector for use with ONYX Series panels.

The FWD-200ACCLIMATE is a wireless Multi-Criteria Detector for use with ONYX Series panels. The FWH-200FIX1is a wireless Fixed Temperature Thermal Detector for use with ONYX Series panels. These multicriteria detector testers produce smoke, carbon monoxide and heat without pressurized cans or hazardous materials, such as silicone.

Testifire produces more than one stimulus at a time, lowering the overall testing time to. Testifire also uses a clearing cycle, which allows detectors to reset without triggering their alarms again. For fire detection, the detector combines the following four separate sensing elements in one unit. CO detector is a plug-in, addressable device that provides both fire and carbon monoxide (CO) detection. This multi - criteria detector uses four sensing technologies (photoelectric, infrare heat, and CO) to accurately detect fire and CO alarm conditions with a high immunity to false alarms.

When paired with the B200S-WH sounder base or B200S-LF-WH low frequency sounder base, the SD365CO can generate unique alarms for fire and CO events (bases sold separately). MCD 573X ( Multi Criteria Detector ) The temperature-aided smoke sensor of the MCD 573X provides early detection of smouldering, glowing and open fires with smoke development. With Cubus levelling the detector adapts to the ambient temperatures prevailing in the room - it automatically regulates its own smoke sensitivity. Edwards, continuing in its legacy as the inventor of the alarm bell, is the first multi - criteria smoke detector manufacturer to receive certification to the UL standard for Fire Alarm Systems UL.

The SMARTcombines separate sensing elements to act as a single unit. CO sensing (using EC technology) for monitoring CO products from a smouldering fire, IR sensing for measuring ambient light levels and flame signatures, optical smoke detection and heat detection. Addressable Detection B501AUS Universal addressable detector base.

IntelliQuad Multi - criteria Sensor. It uses advanced algorithms to interpret signals from each sensor to monitor every product of combustion, while adjusting itself and responding to changing conditions. The E-HD is a selectable rate of rise or fixed-temperature heat detector with a fixed alarm threshold of 135° F (57° C). The detector analyzes data from both sensors to determine when an alarm is initiated. The Signature Series SIGA-PHD detector brings advanced multisensor technology to a practical design that increases efficiency, saves installation time, cuts costs, and extends life safety and property protection capabilities.

The System Sensor Multi - criteria detectors offer a smoke sensing and a heat sensing element. These two elements can be utilised together or seperately, increasing the flexibility of the detector and also is false alarm tolerance. The Axis EN Multicriteria Detector Lite combines a photoelectric and thermal sensing element with a very sophisticated algorithm. A symmetrical smoke chamber ensures optimal smoke sensitivity from all directions.

The double dust trap protects the smoke chamber from airborne contamination and external light. Until this occurs, multi-criteria detectors such as Acclimate must be classified as either a heat detector or a smoke detector. System Sensor has cho-sen to have Acclimate assessed and listed by UL and ULC as a spot type photoelectric smoke detector with supple-mentary 135°F heat detection. The XPmultisensor detector contains an optical smoke sensor and a thermistor temperature sensor whose outputs are combined to give the final analogue value.

The multisensor construction is similar to that of the optical detector but uses a different lid and optical mouldings to accommodate the thermistor temperature sensor.
