Linear heat detection under difficult conditions

Issue 5 2020 Fire & Safety

Securiton’s SecuriHeat ADW535 linear heat detector prevails where conventional fire detectors reach their physical limits. It manages both extreme temperatures and constantly high atmospheric humidity, with precise measurements even in the presence of corrosive gases and contaminated air. Typical applications include:

• Underground garages, vehicle silos.

• Food industry, industrial kitchens, large commercial bakeries.

• Alcohol processing, distilleries.

• Chemical industry, refineries, oil tanks.

• Waste incineration plants.

• Paint shops and other high-temperature environments.

Double tube

SecuriHeat ADW535 uses a physical principle to its advantage: If the ambient temperature increases in the event of fire, the volume of heated air also expands. Air-filled sensing tubes transmit this pressure increase to a sensor in the cable terminal processor. The system triggers an alarm as soon as a defined limit is exceeded. Two sensing tubes (Double Tube) can be connected to the ADW535, effectively doubling the monitoring area, and the system can be optimally adjusted according to the area and applicable installation guidelines.

Dynamic Heat Watch (DHW)

A false alarm is an alarm correctly triggered by a sensor impulse, but there is no actual danger. Brief temperature increases may occur when a gate is opened in a warehouse, for example. The intelligent DHW algorithm on the ADW535 ensures that these types of events are filtered out and not transmitted as an alarm.

IT-based planning and configuration

The Securiton ADW HeatCalc software tool allows system planning at a very early stage. Only a floor plan is needed to begin. The tube layout is sketched with a few clicks of the mouse and the program assists where possible. A detailed report for the plant documentation together with a full required parts list are generated automatically. The design can then be uploaded directly to the device using the ADW Config software tool.

SecuriHeat ADW535 is VdS approved for all EN 54-22 classes and also carries UL and FM approvals.
