AQUA RING
CEILING MOUNT
DIGITAL PASSIVE INFRARED DETECTOR
The microprocessor-based, fully digital AQUA RING detector is characterized by high
sensitivity and interference resistance. Due to an advanced digital temperature compensation
feature, the device can work in a wide temperature range. A dual element pyrosensor is used
in the detector. The processor performs two-way signal analysis, based on value and
quantity.
The detector is provided with a prealarm feature. Prealarm is signaled by a short flash of the
LED after changes which do not meet the alarm criteria have been sensed within the detector
coverage area. The prealarm sensitivity depends on what sensitivity is set on the detector
pins. Frequently occurring prealarms may cause an alarm.
For 30 seconds after the power-up, the detector remains in the starting state, which is
signalized by a rapid LED blinking. Only after this time has elapsed, the detector will be ready
to work.
The detector monitors the supply voltage. If the voltage drops below 9 V (±5%) for more than
2 seconds, the detector will signal a trouble by activation of the alarm relay and by steady
light of the LED indicator. Restoration of a minimum 9 V (±5%) voltage will turn the signaling
off.
Explanations to Fig. 1:
1 - terminals:
NC - relay (NC)
TMP - tamper contact (NC)
COM - common ground
12V - supply input
2 - red color LED to indicate:
– prealarm – short flash (approx. 120 ms);
– alarm – lit up for 2 seconds;
– starting state – blinking rapidly;
– low supply voltage – red light.
3 - pyroelement.
4 - tamper contact.
5 - fixing screw hole.
6 - detector configuration pins:
PIR SENS.
LED ON/OFF - enabling/disabling the LED signaling. The signaling is enabled when
