ADW Line Heat Detection

NSW 02 9644 7144 QLD 07 3252 5366 VIC 03 9544 2211 WA 08 9349 2972 • Configurable response behaviour • Resistant to external influences • Maximum utilisation of the available monitoring area thanks to Double Tube • ActivFire approval, VdS approval for EN 54-22, classes A1I, A2I, BI-GI and FM/UL • HDx (heavy-duty) version with ATEX approval available Double Tube – doubling the monitoring area. Two sensing tubes can be connected to the SEC-ADW-535-2. This means that the monitoring area is doubled and the system can be optimally adjusted according to the area and applicable installation guidelines. Dangers are detected quickly and reliably by each of the sensing tubes. Interventions can then be made efficiently and with pinpoint accuracy. Further advantages include the space savings and price. Many fires cause sharp increases in ambient temperatures. When this happens, the volume of heated air expands. With the SEC-ADW-535 heat detector, Securiton uses this physical principle to its advantage. Air-filled sensing tubes are laid in the room to be monitored. If the temperature increases, then an electronic sensor registers the pressure increase of the air inside the tube. The processor interprets these pressure increases and triggers an alarm immediately as soon as a defined limit has been exceeded. SEC-ADW-535 – better measurement: 5
