Introduction

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.

Introduction

The Simtronics DF-TV7–V is a combined ultraviolet / infrared flame detector offering excellent flame detection whilst maintaining outstanding false alarm immunity. 

The MultiFlame DF-TV7–V is designed to respond to unwanted hydrocarbon fires, whilst maintaining a high degree of false alarm immunity. The DF-TV7-V flame detector uses combined ultraviolet/infrared (UV-2IR) optical technology that provides industry-leading immunity to false alarms based on the two IR channel design.

The device 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.

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.
