Infrared Sensor Wired Ceiling Satel AQUA Ring S

The SATEL AQUA Ring S is a wired infrared (PIR) ceiling-mounted motion detector with a compact oval enclosure measuring 97 mm × 97 mm × 29 mm. Designed for ceiling installation where wall mounting is impractical—for example in rooms with full-height glazing or display cases—the detector covers large open spaces and integrates into 24 V systems. It uses a dual-element PIR sensor and a digital motion detection algorithm that provide reliable detection with improved resistance to interference and false alarms. The device includes adjustable sensitivity, a pre-alarm feature and a tamper switch for enclosure protection. In addition to security detection, the detector can be used for basic building automation tasks such as switching lights or controlling doors when the alarm system is disarmed.

Advantages

The AQUA Ring S offers stable motion detection through a dual-element PIR sensor combined with a digital algorithm that reduces false alarms and improves immunity to environmental disturbances. Its ceiling form factor and compact dimensions make it suitable for locations where wall mounting is not possible, while the built-in pre-alarm and tamper switch add layers of physical protection. Three-step sensitivity control allows on-site tuning to match room size and activity levels. Compatibility with 24 V DC or AC supply makes the unit suitable for systems that operate at higher supply voltages.

Suitable for

• Ceiling-mounted intrusion detection in rooms with glazed or open walls
• Coverage of spacious interiors such as halls, showrooms or retail areas

How to use

Mount the AQUA Ring S to a ceiling surface at the recommended height for optimal coverage and connect it to a 24 V DC or AC supply according to the installation diagram supplied with the device. Adjust the sensitivity control depending on the size of the protected area and typical activity patterns to balance detection range and false alarm immunity. Configure the detector within the alarm control panel or automation controller to assign output behavior for alarm, pre-alarm and idle states. Verify detection coverage by performing a walk test and fine-tune placement or sensitivity as required.

Usage recommendations

Place the detector centrally in the area to be protected and avoid mounting near strong heat sources, air vents or objects that generate rapid temperature changes. Use the three-step sensitivity setting to reduce false activations in environments with frequent movement or temperature fluctuations, and include the tamper switch in routine checks to ensure enclosure integrity.
