DIGITAL PASSIVE INFRARED DETECTOR
AQUA RING
CEILING MOUNT
aquaring_e 06/04
The microprocessor-based, fully
digital AQUA series detectors
feature high sensitivity and
interference resistance. A dual pyro
electric element is used in the AQUA
RING detector.
TERMINALS:
NC
- alarm relay (NC)
TMP
- tamper contact (NC)
COM
- ground (0V)
12V
- supply input (9-16V DC)
Three pairs of pins are used to set the detector working parameters (see Table)

Low sensitivity
Medium sensitivity
High sensitivity
LED indicator ON
LED indicator OFF
- pins open - pins shorted
The LED lights red when the detector is actuated, which enables the installer to
check the detector for correct functioning and to approximately determine the
protected area.
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 ceiling mount. Prior to installation, remove the
electronics board and make adequate openings for screws and cable in the
housing.
Be careful so as not to soil or damage the pyro element in the process of
installation.
