AQUA PRO
DIGITAL PASSIVE INFRARED DETECTOR
The microprocessor-based, fully digital AQUA PRO 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 quad pyroelectric sensor 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
detected within the coverage area. The prealarm sensitivity depends on what
sensitivity is set on the detector pins. Frequently occurring prealarms may cause
an alarm.
The detector requires to warm up for the first 30 seconds after applying power.
Warm-up is indicated by a rapid LED blinking.
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.

Lenses

An extra wide (EWA) lens is installed in the detector. Optionally, lenses with other
characteristics (coverage patterns) can be purchased and installed.

Note: The detector operating range should be selected to match the size of
space where the detector will be installed. The size of the space along the
main direction of detector positioning is not to be less than 1/3 the nominal
range of the detector. Improper selection of the lens may cause excessive
sensitivity and trigger false alarms.

Installation

1. Open the enclosure as shown on Fig. 4.

2. Remove the electronics board.
3. Make suitable openings for screws and cable in the enclosure base.
4. Pass the cable through the prepared opening.
5. Fix the enclosure base to the wall or to the attached bracket.
Note: For compliance with the requirements of EN50131-2-2, the detector shall
be installed directly on the mounting surface, without the additional bracket.
