  • Page 5: Introduction

    The VSF303 has been designed for use in standalone operation. Detector Features • The VSF303 has a 90° cone of vision with a range of 200 ft (60 m) to a 1 ft (0.1 m ) pan fire of n-heptane.

  • Page 6: Safety Instructions

    For European (ATEX) installations IEC/EN60079-14 ‘Electrical Installations in Hazardous Areas’ and ICE/EN60079-17 ‘Inspection and Maintenance in Hazardous Areas’ should be strictly observed. The IR3 type flame detector; Viking VSF303, is to be installed in places where there is a low risk of mechanical damage.
  • Page 7 The VSF303 is not designed to annunciate diagnostic failure of signal returns via external wiring. Control systems and fire panels generally have fault monitoring for such an eventuality.
