Spectron 400 Series Flame Detector

Flame detectors with intrinsically safe circuit type of protection:

• Spectron-401-Exi
• Spectron-401.01-Exi
• Spectron-401-Exi-M
• Spectron-401.01-Exi-M

Explosion protection marking РО Ex ia I Ma X / 0Ex ia IIC T6 Ga X / Ex ia IIIC T85ºC Da X allows the detector to be used in hazardous areas Zones 0, 1 and 2

An intrinsically safe circuit is required to connect an intrinsically safe detector.

The detector is connected to an explosion-proof control panel with an intrinsically safe output or to a general industrial control panel through an intrinsically safe barrier. Manufacturer recommended IS barriers:

• Spectron-IB-01 – 12 V/500 mA, for conventional detector with 4-wire connection;
• Spectron-IB-02 – 24 V/100 mA for conventional detector with 2-wire connection to the alarm control panel;
• S2000-Spectron-IB - for an addressable detector when included in the DPLS loop

Flame detectors with encapsulation in a compound type of protection:

• Spectron-401-Exm
• Spectron-401.01-Exm
• Spectron-401-Exm-M
• Spectron-401.01-Exm-M

Explosion protection marking PB Ex mb I Mb X / 1Ex mb IIC T6 Gb X / Ex mb IIIC T85ºC Db X allows the detector to be used in hazardous areas Zones 1 and 2

An intrinsically safe circuit is not required to connect a detector with the encapsulated within a compound type of protection. Cables have to be laid considering the requirements of the PUE (section 7.3) for electrical wiring in hazardous areas.

Spectron-401 series flame detectors are recommended for use in indoor fire alarm systems

Housing of Spectron-401, -401-Exi, -401.01-Exi, -401-Exm, -401.01-Exm is made of high-strength ABS plastic

Housing of Spectron-401-M, -401-Exi-M, -401.01-Exi-M, -401-Exm-M, -401.01-Exm-M is made of galvanized steel

The field of view of Spectron-400 series is 100º in the vertical, horizontal and all inclined planes.

Flame detection range in accordance with GOST R 53325-2012 - 50 meters to TP5, 25 meters to TP6

Spectron-401 series detectors with "01" index (flash detectors) are designed for instantaneous (from 0.1 s.) detection of specialized fires. Before using "flash detectors" it is highly recommended to get advice from the technical support service of NPO Spectron by tel. 8-800-500-1073

Minimal response time, seconds

The transition of the detector from the Alarm mode to the Normal mode is carried out by disconnecting the power supply for at least 2 seconds

• The temperature range of the detector in plastic housing is -55 to +75 ºС.
• Temperature range of the detector in metal housing is -55 to +85 ºС

The detector with the "M" index is manufactured in a housing made of galvanized low-carbon steel and is recommended for use in conditions with a high probability of mechanical damage to the detector
