Precision and reliability are key focuses in the design of the Securi-RAS technology, with new additions to the range bringing even greater flexibility in providing early warning against fire.

Two new detectors will be introduced on the Patol stand at this year’s show. The ASD 531 is a one-channel detector for monitoring smaller premises, offering quick commissioning through configuration directly from the device rather than requiring a PC. The ASD 532 is also a one-channel detector featuring a smoke-level indicator which offers a compact solution for small to medium-sized applications. It can accommodate a sampling tube length of up to 120 metres and works effectively at temperatures from -20°C to 60°C. The compact design of the ASD 532 makes it an ideal solution for applications where space is at a premium such as lift shafts, IT racks and prison cells. Both of the new detectors use the same tried and tested HD detector with its large volume smoke chamber providing outstanding sensitivity combined with an impressive long service life.

The new additions join the existing ASD 535 which is available in one or two-channel options to provide high sensitivity detection for large-scale areas of up to 5,760 square metres (up to 300 metres of sampling pipe). The detector features one of the most powerful fans available on the market (400 pa of aspirating under-pressure) and is ideal for use in harsh environments, including deep-freeze areas, explosion hazards or rooms which are characterised by their high volumes of contamination. Multiple ASD 535 detectors can be networked through the use of a master module, allowing 240 sensors to be connected to a single network.

EN54-20 Class A, B & C approved, all of the detectors use scattered light technology to detect even the slightest increase in smoke concentration.

In addition to offering Securiton’s ASD technology, Patol will be using Firex International to showcase its own range of linear heat detection cables (LHDC), including new additions introduced to detect fire at a broader range of temperatures.
