The Simtronics DF-TV7–T is a multi-spectrum infrared flame detector using three wavelengths. DF-TV7-3IR responds to hydrocarbon fires and is the right choice for operation in dirty environments or for detection of smoky fires.
The MultiFlame DF-TV7–T is designed to respond to unwanted hydrocarbon fires, whilst maintaining a high degree of false alarm immunity. The device offers a wide range of output options, as standard and is suitable for use in SIL 3 applications. The unit may be interfaced directly with a wide range of fire panels, controllers and PLC’s etc.
The 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 are also possible using the TLU.
