DTD-210A

The 200 series of addressable detectors has been developed using the most innovative technical advances. Its completely new design makes the 200 series one of the most elegant on the market, ideal for facilities in which the balance between functionality and aesthetics is necessary. Detnov’s 200 range of addressable detectors is made up of 4 detector types, all of them available with and without isolator. There are a 58ºC rise-of-rate detector, a 78ºC heat detector, an optical detector and an opticalheat detector. All of them are compatible with Detnov’s CAD-150 and CAD-250 families of addressable control panels. The 200 series of addressable detectors’ addresses are assigned through the PGD-200 programmer (Isolator version support auto adressing). The use of this tool saves double address mistakes, because the programmer automatically handles the address to be assigned. Connections between the addressable system’s detectors and modules must be made with a 2 x 1.5 mm2 twisted and shielded cable with a maximum length of 2 Km (changing the seccion of the cable, number of element and using calculation software loop can reach up to 3500m). To meet the EN-54 requirements, the wiring must be done in a closed loop. Precise short-circuit isolators must be installed to facilitate the location of possible faults. The loop accepts up to 250 addresses. The DTD-210A rise-of-rate detector detects a quick temperature increase in a fixed period of time, or a temperature higher than 58ºC. In both cases the detector will go into alarm status, and the detector’s integrated LED will light up. The temperature control is carried out through a thermistor which is controlled by a circuit, based on the most advanced technology. The 200 series detectors require the Z-200 base in order to connect. This connection base includes a blocking option which avoids it being tampered with. A tool is needed to remove the detector from the base. Detectors in this series have non-polarity technology, facilitating system wiring and saving a huge amount of time in commissioning the system.
