DIGITAL PASSIVE
INFRARED DETECTORS
AQUA & AQUA Pro
aqua_dwa_e 06/04
The microprocessor-based, fully digital
AQUA series detectors feature high
sensitivity and interference resistance.
The AQUA detector employs a dual
pyro electric element, and the
AQUA Pro - a quad element.
CONTACTS:
NC - alarm relay (NC)
TMP - tamper contact (NC)
COM - ground (0V)
12V - supply input (9-16V DC)
Three pairs of pins are used for setting
the detector working parameters (see
Table).
The LED lights red for approx. 2s when
the detector is actuated, which enables
the installer to check the detector for
correct functioning and to
approximately determine the protected
area.
The detector features a prealarm
function. The prealarm does not
actuate the relay and is indicated by
a short flash of the LED, lasting
approx. 120ms. It is activated when the
ambient disturbances recorded by the detector do not meet the alarm criteria. The
prealarm sensitivity is not affected by the detector sensitivity, which is set with jumpers.
For 30 seconds after the power is turned on, the detector remains in a starting state,
which is signalized by rapid LED blinking. Only then the detector enters its operational
readiness state.
The detector monitors the supply voltage. If the voltage drops below 9V (±5%) for more
than 2 seconds, the detector will signalize a violation state until a voltage of minimum 9V
(±5%) is restored.
INSTALLATION
The detector is designed for indoor installation. It can be mounted on the wall, either
directly or on the included holder. Prior to installation of the detector housing, remove the
electronics board and make adequate openings for screws and cable in the rear panel of
the housing. It is advisable that you exercise particular care to prevent the pyro
element from getting dirty or damaged during installation.
The scale provided on the detector board (see Fig.1) is intended for properly setting the
pyro element against the lens installed in the housing. If the detector is to be mounted at
