AQUA S digital passive infrared detector with dual pyroelement

AQUA S is a digital passive infrared detector equipped with a double pyroelement, designed for operation in systems powered by 24 V AC/DC. The device uses a digital motion detection algorithm, which improves resistance to interference and false alarms.

• Digital passive infrared detector with dual pyroelement
• Digital motion detection algorithm to reduce false alarms
• Interchangeable Fresnel lens and three-stage sensitivity adjustment
• Pre-alarm function and tamper contact to protect against opening the housing
• AC or DC 24V AC/DC power supply

Application and functions of AQUA S detector

The primary purpose of the AQUA S detector is to detect a violation in the protected area in intrusion detection systems. With the ability to replace the Fresnel lens and three-stage sensitivity adjustment, the detection characteristics can be adapted to the specifics of the room and user requirements. The built-in pre-alarm function allows the system to react in advance to emerging movements, and the tamper contact provides protection against unauthorized opening of the device's housing.

The detector can also be used to perform building automation functions when the alarm system is not activated. In such applications, the signal from the detector can control, for example, the lighting on, as well as the opening or closing of doors, which increases the comfort of the protected facility without the need for additional motion detectors.

Design and operating conditions

The design of the AQUA S detector includes a double pyroelement and a digital signal processing algorithm, which improves the stability of operation and resistance to environmental interference. The 63 x 96 x 48 mm housing provides a compact footprint for unobtrusive use in various types of rooms. The device meets the requirements of environmental class II and is suitable for operation in a wide temperature range of -30 to +55 °C, which allows installation in various climatic conditions.

The detector is designed for systems operating on voltages other than the standard 12 V - it can be powered by 24 V AC/DC, with a rated supply voltage of 24 V AC/DC ±15%. The maximum current consumption is 27 mA or 14 mA (depending on the operation mode indicated in the documentation), and the weight of the device is 93 g. The recommended mounting height is 2.4 m, which allows for a proper detection field according to the characteristics of the Fresnel lens used. The detectable speed of movement is within the range of 0.3 to 3 m/s, which corresponds to typical human movements in the protected area.
