Gira KNX presence detector Standard

• Precise presence and motion detection
• Daylight-dependent lighting control
• Energy-saving optimisation of the delay time
• Three digital PIR sensors

• Sensor sensitivity can be adjusted individually
• Diverse potential applications
• Large detection range
• Integrated bus coupler

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.

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

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 using the teach-in function on the device, or by using any operating devices such as the Gira pushbutton sensor 3.

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.

Adaptive delay time:

The Gira KNX presence detector Standard offers the option of continuously analysing user behaviour, thereby independently optimising the delay 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 delay time. In contrast, if a room is only entered for a brief period, the Gira KNX presence detector Standard also selects a short delay 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 delay 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 delay 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.

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

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).

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.
