A line-type detector supplied by Patol has been selected as the heat detection method in a new fire protection installation in a laboratory working in a Hazardous environment operating within a Ministry Of Defence site.

The fire safety at the laboratory is provided through a Fire Detection system installed by Honeywell featuring a SecuriSens ADW 535-2 line-type heat detector connecting to an extinguishant Fire Control Panel. The detector from Securiton, for whom Patol is the distributor in the UK, is a two-pipe, two-zone system. The sensing tubes filled with normal air have been installed in the areas within the laboratory being monitored, with a fully electronic sensor permanently recording the pressure within the tubes. As a double-knock system, the alarm criteria for both zones must be met before the CO2 extinguishant is released, thereby significantly reducing the potential for false alarms.

The SecuriSens detector can operate in harsh environments subject to corrosive gases, extreme humidity and high temperatures.

A significant benefit of the detector is its low maintenance requirements, with an extremely tough sensing tube (available in stainless steel, copper or Teflon), making it particularly suitable for applications in which functional and maintenance checks are not possible or difficult to undertake. In addition to laboratory environments, it is widely employed in diverse applications, from tunnels, parking areas and loading ramps to vehicle paint spray booths, distilleries and waste treatment facilities.

The detector meets the requirements of EN 54-22 and offers sufficient internal memory to store up to 1,000 events, with a read-out function offering a timestamp and detailed description of each event.
