DF-TV7 IR3 Flame Detector (SIL3)

Technical Description – Simtronics DF-TV7 IR3 Flame Detector

The Simtronics MultiSpectrum DF-TV7 Triple IR flame detector is designed to respond to unwanted hydrocarbon fires, whilst maintaining a high degree of false alarm immunity. The IR3 Multi Flame device offers a wide range of output options, as standard and is suitable for use in SIL3 applications 

A Closer Look

• Continuous auto-check of optical lens  
• Relays, 4-20mA, 0-22mA, Hart outputs  
• Long range up to 80m, 260 ft deep 
• Wide field of view 120°  
• SIL3 

All Simtronics Multi Spectrum IR3 Flame detectors are equipped with a continuous optical lens integrity auto-check to ensure that the optical path is clear and that the detector functions properly. Sensors can be replaced easily in the field without removing any cable glands.  

Control System Integration

The DFTV7 may be interfaced directly with a wide range of fire panels, controllers and PLC’s etc. The flame detector unit is fully configurable using a wireless hand-held terminal (TLU) or optionally via HART (R) giving true flexibility to the installer. Time delays, sensitivity and output configuration are all set up via the TLU; a hazardous area approved hand-held unit. Wireless testing of the optical and output circuits is also possible using the TLU.
