Gira KNX presence detector Standard

Energy-efficient light and climate control

The Gira KNX presence detector Standard is used for presence monitoring and motion detection indoors. It is installed on the ceiling and detects even the slightest motion in a range of 360°. This enables various functions in the KNX system such as lighting, heating, and ventilation to be controlled entirely as required and in an energy-efficient manner. Three digital PIR sensors ensure quick and precise motion detection. The crossed light paths of the sensors ensure that the detection range is covered without any gaps.

A brightness sensor is integrated for daylight-dependent lighting control. In addition, the Gira KNX presence detector Standard is able to analyse user behaviour and independently optimise the overrun time. This saves energy and conserves the light source by preventing unnecessary switching on and off. Only a minimum and maximum value must be specified for this purpose. Depending on the duration of the movement detected in the room, the Gira KNX presence detector Standard will select a correspondingly short or long overrun time.

Precise presence and motion detection

The Gira presence detector Standard doesn't miss a thing: It is equipped with three digital PIR sensors, which cover a range of 360° (3 x 120°). At a mounting height of 3 m, it has a nominal range of approximately 12 m at desk height and 20 m at floor height.

Sensor sensitivity can be adjusted individually

The sensitivity of the three PIR sensors can be set individually and flexibly adapted to individual installation scenarios – which enables movements to be reliably detected and prevents accidental triggering. In addition, the range of detection can be limited using a clip-on screen.

Daylight-dependent lighting control

An integrated brightness sensor measures the current light intensity, thus providing the option of lighting control depending on the daylight available. This means that the lighting is only switched on when the room is not bright enough. If there is sufficient daylight, the lights stay off. The dusk stage of the brightness sensor can be set via the ETS, by teach-in function on the device or using any control devices such as the Gira touch sensor 3.

Diverse potential applications

The Gira KNX presence detector Standard can be used as an individual device, main unit, or auxiliary unit, and is thus suitable for equipping a wide range of properties. When used as a main unit or auxiliary unit, semi-automatic, as well as fully-automatic control is possible. There is a choice of three preconfigured operating modes: presence detector, ceiling monitor and alarm device.

Energy-saving optimisation of the overrun time

Adaptive overrun time:

The Gira KNX presence detector Standard offers the option of continuously analysing user behaviour, thereby independently optimising the overrun time (transmission delay). This saves energy and conserves the light source by preventing unnecessary switching on and off. The longer the period during which motion is detected in the room, the longer the overrun time. In contrast, if a room is only entered for a brief period, the Gira KNX presence detector Standard also selects a short overrun time. Occupants can freely define the minimum and maximum values themselves.

Short-term presence function for conference or training rooms:

The short-term presence function was developed as an addition to the adaptive overrun time especially for light and climate control in conference and training rooms. If the Gira KNX presence detector Standard detects motion only briefly, it selects the minimum overrun time regardless of the self-taught value. As a result, lighting, heating, and ventilation will not remain switched on unnecessarily if somebody enters the room temporarily during a long conference break, e.g. the cleaning staff or catering service.

Large detection range

The maximum range of detection on the ground is approx. 20 m for a mounting height of 3 m.

Influence of the direction of motion on the size of the detection range

Movements of people who pass by the side of the device (tangential, left) can be detected from a greater distance than movements of people approaching or moving away from the device straight on (radial, left).

Installation

The Gira KNX presence detector Standard is delivered as a ready-to-connect complete device with an integrated bus coupler for flush-mounted installation. The device can also be fastened directly on the ceiling with the optional surface-mounted housing. When used as a motion detector, installation heights between 2.20 m and approx. 5 m are possible. If the device is used as a presence detector, a mounting height of 3.5 m should not be exceeded.
