On the market, there are many movement detectors based on a PIR sensor. For a simple usage, like for example lighting of a garage entry. Probably, it´s not necessary to use a top quality sensor with exactly defined specification and with wide possibilities of adjustment if you´d like to use it for example for a simple lighting of a garage entry. But a for a frequented corridors, security devices, lighting switching, … it´s surely beneficial if having a detector which we can rely on. Detectors from company Finder belong to such category. Finder offers five basic series:
● 18.01/18.11 - detector with a wide detection angle and a universal assembly with a possibility of an easy selection of a spce to survey. Typ 18.01 is suitable for indoor applications, 18.11 also outdoor.
● 18.21/18.31 - detector for ceilings with a surface or recessed assembly
● 18.41 - detector for hotel or office corridors, up to 30x4m range (depending on a height of a ceiling)
● 18.51 - highly sensitive ceiling type with a square detection pattern (up to 8x8m), suitable for schools, offices and also low activity zones. High sensitivity enables operation in 2 modes - “presence” and “movement”. In this case even a minimum movement, like for example a work on a PC is sufficient to activate the detector. Such a sensitivity can help to prevent for example an unwanted locking of building and activation of alarm, when you already think, that there´s nobody inside (but in fact, somebody is still there :-)).
● 18.61 - specific product for a wall assembly, 180° angle of survey, detects a half-circle with up to 18m diameter.
All types have elements for adjustment - ambient light sensitivity and a switch-on time of a contact (from a last detection). New types - 18.41, 18.51 and 18.61 also have the third adjusting element - sensitivity of the sensor itself. Thanks to them, it´s possible to adjust a detector to meet requirements of a given application. Logic of switching is an “addition”, i.e. if in time of a switched-on contact occurs another detection, the sensor will prolong the switch-on time for the selected time, i.e. no switch-off of the output contact (neither a short one) will occur. All types are designed for mains applications (96-253VAC) and they have a relay output (10A contact). Contact at types 18.41, 18.51 and 18.61 is also able to switch 400VAC.
Types 18.41, 18.51 and 18.61 are supplied with a rich set of accessories enabling a comfortable and aesthetic mounting as suspended ceiling, recess mounting (for example into a wall) and surface mounting.
Detailed information will provide you the Finder 18.01-31 and Finder 18.41-61 datasheets as well as the Finder 18 flyer (DE) and the attached video.
