Simtronics DF-TV7-V UV/IR Flame Detector

The MultiFlame DF-TV7–V 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 2 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.
