MG/MGR-2000 SERIES CONVENTIONAL FIRE DETECTORS

Superior design and excellent functional features of the MaviGard detectors are the result of the Research & Development work done using latest technological achievements in the fire alarm industry. Detectors are produced with Surface Mount Technology (SMT). Detector PCB is protected against electromagnetic interference with metal case and against corrosion by minimizing contact with external medium. MG series detectors are compatible with all fire alarm control panels, MGR series detectors are compatible with all security alarm control panels. All detectors are provided with blue plastic cover, which protects detector from dust, dirt etc. during construction and paint. Detectors are produced in white as standard but, according to customer's choice, various colours are available. Detectors can be provided with magnet-testing feature on customer's demand.

MG-2100 Photo-Electric Smoke Detector

MGR-2100 Photo-Electric Smoke Detector with Relay Output

Photo-electric smoke detector utilises the light scatter sensing principle. It has an infrared light source which emits signals and a photo-diode which senses the scattering light with the effect of smoke entering the chamber. The chamber is protected with thin metal mesh for protection from dust, insects and other external interferences. The detectors are EN 54-7 and EMC Directive 89/336/EEC certified.

MG-2200 Ionisation Smoke Detector

MGR-2200 Ionisation Smoke Detector with Relay Output

Ionisation smoke detector has twin room ionisation chamber to prevent the interference of excessive humidity and heat. One of the rooms functions as a reference and the other as the sampling one. The chamber is protected with thin metal mesh for protection from dust, insects and other external interferences. The detectors are EN 54-7 and EMC Directive 89/336/EEC certified.

MG-2300 Rate of Rise Heat Detector

MGR-2300 Rate of Rise Heat Detector with Relay Output

Rate of rise heat detector detects temperature change by two temperature-sensitive thermistors. The detector can function either as a fixed heat or rate of rise heat detector. Fire alarm signal is generated in case of 300C /min or higher heat rise and/or on reaching the threshold of 600C. The design of the chamber provides sensitive ambient temperature measuring. Design of the detector provides fast response to heat rise. The detectors are EN 54-5 and EMC Directive 89/336/EEC certified.

MG-2400 Fixed Heat Detector

MGR-2400 Fixed Heat Detector with Relay Output

Fixed heat detector detects temperature change by one temperature-sensitive thermistor. The fire alarm signal is generated on reaching the threshold of 600C. The design of the chamber provides sensitive ambient temperature measuring. Design of the detector provides fast response to heat rise. The detectors are EN 54-5 and EMC Directive 89/336/EEC certified.

MG-2500 Multisensor (Photo-Electric Smoke

and Fixed Heat Detector)

MGR-2500 Multisensor (Photo-Electric Smoke

and Fixed Heat Detector) with Relay Output

Multisensor series fire detector has features of both photoelectric smoke and fixed heat detector. It has an infrared light source which emits signals and a photo-diode which senses the scattering light with the effect of smoke entering the chamber. The chamber is protected with thin metal mesh for protection from dust, insects and other external interferences. The detector measures the temperature change by one thermistor. Design of the detector provides fast response to smoke and heat rise. Detectors are EN 54-5, EN 54-7 and EMC Directive 89/336/EEC certified.
