Finder Type 18.5K – KNX Presence and Movement Detector

Finder.jpg

A new technological product has been added to the range of presence and movement detectors of Series 18: this is the type 18.5K detector with KNX technology.

Type 18.5D

 

The new movement sensor uses the reliable and tested detection technology that already characterizes the previous Series 18 detector models and is suitable for applications in building automation systems featuring the KNX standard.

Technical features:
Specifically designed to sense micro movements, this sensor is the ideal solution for the management of lighting systems in offices and work environments in general and schools.

The sensor lens has been developed to obtain higher sensitivity in the detection of micro movements and guarantees two reading and sensitivity areas, identified as
•a movement area, which is larger and covers an area of 8×8 m;
•a presence area, which is more important for detecting small movements, and covers an area of 4×4 m.

The type 18.5K movement and presence sensor is provided with 2 software outputs, one of which is controlled according to the light measured by the internal sensor (this function can be disconnected), and is also appropriate for particular types of systems where it is necessary to control both the lighting and the heating/air conditioning.

There is also a third software output that sends only movement information to the KNX Bus: thanks to specific software inputs, sensors can be networked in Master/Slave configuration. This functionality is particularly suitable for controlling large rooms.

Accessories included in the package:
The detector is supplied complete with supports that can be used for ceiling or suspended ceiling mounting and is powered directly by the KNX Bus.

Finder Introduces Type 18.5D Movement and Presence Detector

Finder.jpg

Type 18.5D

Finder presents its new movement and presence detector Type 18.5D with Bluetooth programming technology, and DALI (Digital Addressable Lighting Interface), making programming through a smart phone easier than ever.

The detection of small movements make this detector particularly well suited for applications in schools, offices and other environments where there is not necessarily high levels of movement.

A special lens has been developed to sense both normal movements and micro movements. Normal ‘movement’ is detected over the wider area of 8 x 8 meters, while the ‘presence zone’ has increased sensitivity for the detection of small movements within a central area of 4 x 4 meters.

Through the use of Bluetooth LE (Low Energy) technology programming the detector’s operating characteristics can be easily and conveniently done using an Android or iOS smartphone.

After installing the 18.5D, simply download the Free App Finder Toolbox from Google and Apple’s official stores and set all the required parameters.

Finder Type 072.11 New Relay and Sensor Combination Detects Liquid Leakage

Finder.jpg

Finder Type 072

With the recent reminders of the need to protect against flood water and other detrimental water leakage, Finder has expanded its range of liquid level control relays with the introduction of the 072.11 surface water sensor.

Working in conjunction with a liquid level control relay from the 72 series range, the surface water sensor has been designed to sense water levels as low a 1 mm, making it ideal for a range of applications, from detecting spillage around vending machines in sensitive areas such as computer suites, to the early detection of flood water in the basement or ground floor of a home.

Reinforced electrical isolation between the three circuit elements within the level control relay helps the system designer meet the personal safety required in virtually all equipment standards, and low voltage makes the sensor safe to touch.
