Teledyne DF-TV7 Series Flame Detector
The Teledyne DF-TV7 Series Flame Detector offers a wide range of output options, as standard and is suitable for use in SIL 2 applications. The detector can be configured to communicate with a wide range of fire panels, controllers, and PLCs and offer HART 7 and Syntel (Lonworks) protocols for addressable event monitoring. The devices come standard with a configurable 4-20mA or 0-22mA (PLC) output, two configurable alarm relays, and two detector status LEDs.
The MultiFlame range has two versions:
- DF-TV7-T multi-spectrum Infrared flame detector using three wavelengths. Used in dirty environments, for detection of hydrocarbon and smoky fires. SIL3 certified.
- DF-TV7-V multi-flame combined ultraviolet /infrared flame detector. Used in difficult environmental conditions, such as combined rain and wind, rapid sunshine variations, hot sources modulations, industrial lighting etc. SIL2 certified. UV can be sensitive to welding radiation or lightning, X rays and gamma rays.
- 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
- Range previously by Simrad Optronics
All MultiFlame detectors are equipped with a continuous optical lens 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. Devices are easy to test and configure using a TLU600 wireless hand-held unit that is approved for use in hazardous areas. The TLU600 can also be used for wireless testing of the optical and output circuits. The TLU600 can also be used for wireless testing of the optical and output circuits.
