Two-position detectors security line radio wave detectors PREDEL, designed for use as a means of security signalling. The detectors provide detection of a person crossing the detection zone (ZO), and the issuance of an alarm notification by opening the alarm loop circuit when the intruder crosses the ZO. The detectors are characterised by a small width of the required exclusion zone.
The detectors without the index "A" remain operable at temperatures from 233 to 338 deg. K (minus 40 degrees C to 65 degrees C). The detectors with index "A" remain operable at temperatures from 213 to 338 deg C (from minus 60 deg C to 65 deg C). K (minus 60 degrees C to plus 65 degrees C). Detectors with index "B" are made in explosion-protected version and maintain operability at temperatures from 213 to 338 deg C (from minus 60 deg C to plus 65 deg C). K (from minus 60 degrees C to plus 65 degrees C).
The detectors use unregistered operating frequencies of 24.15 GHz. The following equipment can be included in the detectors' delivery set.
