Satel AQUA S Dual PIR Motion Detector 140° 15m, with Pre-Alarm Function and Interchangeable Lens - 24V AC/DC Power Supply

The microprocessor-controlled, fully digital Satel AQUA S detector is characterized by high sensitivity and resistance to interference. Thanks to its state-of-the-art digital temperature compensation mechanism, the detector can be used in a wide temperature range.

Pre-Alarm Function
The pre-alarm is indicated by a brief flash of the LED when disturbances detected by the sensor in the monitored area do not meet the alarm criteria. The sensitivity of the pre-alarm depends on the sensitivity of the detector, which can be set at the pins. Frequent pre-alarms can trigger an actual alarm.

The first 30 seconds after the power supply is turned on is the startup time of the detector, indicated by rapid blinking of the LED. Only after this time has elapsed is the detector fully operational.

• Can be powered by either DC or AC 24V.
• Dual pyro element.
• Universal mounting bracket included.
• Tamper protection against opening the housing.
