Control by motion sensors

Lighting in some spaces can be controlled by the PIR detectors, which switch lights on an off depending on the activity of people, the level of outdoor lighting and other conditions.

This solution is mainly suitable for the lighting of communication lines in the house (e.g. children do not need to look for switches at night), or automatic control of lighting in selected rooms.

PIR intrusion detectors can evaluate the movement of people, either by connecting the detectors directly to the Foxtrot system (which provides the function of the ESS control panel), or indirectly by reading the information from the PIR detectors of a separate ESS control panel connected to the Foxtrot system by a communication interface.

It is necessary to count with a slower response of the PIR intrusion detectors to a motion detection (a change in the setting of the detector, e.g using a jumper, etc., can to some extent help to eliminate false alarms), and also the location of the PIR intrusion detector in accordance with the security of the building may not always be consistent with the requirements for e.g. lighting control (the detector is located to primarily intercept an intruder entering e.g. through the window, while the lighting control system needs to capture the person entering through the door, etc.).

In some cases it is better to use the PIR detectors to control the lighting directly - either they need to be positioned to optimally respond to the movement of people inside the house, or in locations where the security system is not installed.

There is a CFox module we have designed specifically for these applications, the C-RQ-0400R-PIR, which is supplied in a number of designs according to the customers´ wishes - see the example below,

or you can connect suitable PIR detectors to the DI inputs of the Foxtrot system. Either conventional intrusion detectors can be used, or special PIR control detectors - e.g. the Vantage FL-MS MINI mentioned in the example below, which have the optimum position in the room in terms of controlling the lighting.
