The new 200 series of analogue 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 analogue detectors is made up of 4 detector types. They are a 58ºC rise-of-rate detector, a 78ºC heat detector, an optical detector and an optical-heat detector. All of them are compatible with DETNOV’s CAD-150 family of analogue control panels.

The 200 series of analogue detectors’ addresses are assigned through the PGD-200 programmer. The use of this tool saves double address mistakes, because the programmer automatically handles the address to be assigned.

Connections between the analogue 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. 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 elements.

The DOD-220A smoke detector is based in an optical dark chamber, which, thanks to its design, avoids unwanted air flows and facilitates the guidance of the smoke to the optical sensor. The detection principle is based on the Tyndall effect; the detector goes into alarm status due to the scattered light caused by the smoke particles being received by the optical sensor. The camera is protected to avoid the entrance of dirt and insects. This detector also incorporates compensation algorithms which avoid false alarms due to the dirtiness of the optical chamber, postponing equipment maintenance.

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.

The protected area is 60 m2 and the maximum installation height is 12 meters.
