  • Suitable for Class 1 Division 2 applications - Groups A, B, C and D.
  • Up to 2,000 m² coverage.
  • Up to four inlet pipes.
  • Total pipe length up to 360 m.
  • Five high intensity status light emitting diodes (LEDs) for greater visibility.
  • Robust absolute smoke detection.
  • Intelligent filter.
  • Lint trap to capture fibrous particulates.
  • Sub-sampling probe (inertial separator).
  • Secondary filter.
  • Clean air barrier for optics protection.
  • Referencing.
  • AutoLearn™ Smoke and Flow.
  • Clean Air Zero™.
  • Air-path monitoring.
  • Five relays (Fire, Fault and 3 configurable).
  • Relays configurable as latching or non-latching.
  • Expandable GPI and relays.

Accessories

Power supply unit - VPS-220-E5.

Guidance for specification option:

This is the original unit within the range. Internally is an EN 54-4 certified Power Supply rated to provide a 0.5 A continuous 24 V d.c. supply while also charging the batteries (not supplied) which can be a 7, 12 or uniquely, 14 Ah arrangement. As such the unit can be used with confidence to power, and provide 24 hr standby (plus 0.5 hr in alarm), for the VESDA detectors.

Power supply unit - VPS-215-E5.

Guidance for specification option:

This is the budget unit within the range. It is intended as a low-cost unit to supply a single pipe ASD detector which only requires 7 Ah batteries such as the VESDA VLF-250. A simple but elegant construction and no LEDs on the lid keep the cost of the unit to a minimum. The unit can also be inverted where necessary by rotating the lid. The internal charger is EN 54-4 certified and internal LEDs are provided to indicate OK (output healthy) and Fault.

Power supply unit - VPS-250-E5.

Guidance for specification option:

This power supply is capable of powering larger ASD units. It may also be used for installations with multiple detectors and/ or remote displays. The internal charger is EN 54-4 certified to power loads up to 3 A with space and charging capacity for batteries up to 38 Ah. Uniquely, the unit is supplied with the provision to deliver 4 separately fused outputs – recommended when it is used to power multiple detectors or disparate loads.
