with two outputs,

180° surveillance, for wall mounting

Microprocessor-based h i g h l y s e n s i t i v e passive infrared presence detector

w i t h d a y l i g h t s e n s o r for demand-dependent control of lighting systems,

especially in rooms frequently used, and for the control of HVAC equipment.

Operates on AC 230 V, control output AC 230 V for lighting and potential-free

HVAC control output.

The QPA82.1 presence detector is a self-contained unit designed for demanding control

of lighting systems and HVAC equipment.

It is used especially in spaces that are occupied on a temporary basis, where the

presence of a moving infrared source (persons, vehicles, etc.) shall be detected with

great reliability, even at great distances.

One special field of use is ceiling mounting, enabling the space to be divided into

vertical sections with clearly defined detection zones.

The presence detector can be used in all kinds of spaces where, for maximum energy

savings, demand-dependent control is given preference over fixed time scheduling.

• Long corridors, halls, subterranian garages, entrance halls, auditoriums, training and

conference rooms, or

• Workplaces where the light should not be switched on by people passing by (ceiling

mounting).

• Especially in rooms that are frequently used, spaces requiring an extensive detection

zone, or

• Where vertical sections with clearly defined detection zones are required (version for

wall mounting fitted to the ceiling).

• Control of lighting systems

Control of fans

• Switchover of temperature setpoints

• Activation of room air conditioners

• Control of circulating pumps

Functions The QPA82.1 presence detector has an infrared sensor which detects changes in passive infrared radiation in the space, which are then converted into electric control pulses. It captures changes in the thermal pattern caused by the smallest physical movements. This is achieved by making a comparison of the thermal radiation of the moving infrared source (person, vehicles, etc.) and the constant thermal radiation of the environment.

fitting, the inscriptions on both unit sections must be mirror-inverted. Caution! Do not exert any pressure on the plastic insert (optics) of the unit! • After applying the operating voltage or after fitting the detector, the unit will be switched on for 1.5 min (initialization phase), that is, the lighting and HVAC outputs are deactivated. This is followed by a 9-minute service phase. During that phase, the output for lighting responds with no delay if the brightness changes.
