The design of the new analog detectors of the 200 series uses the latest technological advances. Their innovative style converts the 200 range into one of the most elegant on the market and the ideal solution for installations that seek a balance between functionality and aesthetics.
The Detnov range of detectors in the 200 series is available in 4 models: a thermovelocimetric detector (58 ºC), a thermal detector (78 ºC), an optical detector and an optical-thermal detector. All of these devices are compatible with the Detnov analog units of the CAD-150 family.
The address of the analog detectors of the 200 series is assigned by means of the PGD-200 programmer. The use of this tool avoids any duplicate error, since the operation is performed automatically.
The detectors and modules of the analogue system must be connected using a twisted and shielded 2 x 1.5 mm2 cable, limited to a maximum loop length of 2 km and ensuring that the loop is closed (EN-54 requirements). The necessary short circuit isolation modules must be installed to simplify the location of any faults. The maximum number of elements that the loop can support is 250.
The DTD-215A is triggered in the event of a rapid increase in temperature within a defined period of time (EN54-5 value for C-grade detectors) or when the temperature reaches 78ºC. In both cases, the detector switches to the alarm state and its LED lights up.
The connection of the analog detectors of the 200 series is imperatively dependent on the presence of the Z-200 connection base. This base, provided with a locking mechanism that prevents its manipulation, can be removed only by the use of a tool.
Thanks to the technology they use, the polarity of the detectors in this series does not matter. This specificity minimizes connection errors and saves a lot of time during installation.
The covered protection area is 20 m2 and the maximum installation height is 6 m.
