AT-OPSEN
Optical Sensor
INSTALLATION INSTRUCTIONS
General Information
Please read these instructions carefully and
keep them in a safe place for future reference.
These instructions must be followed to ensure
proper operation.
The OPSEN optical sensor has been
specifically designed for use with TraceTek
and AquiTron™ leak detection systems.
The OPSEN is designed for use in ordinary
areas with temperatures of 0°C to 50°C (32°F
to 122°F).
Zones / Regions
Probes with terminal strips and built in
resistors (weighted lengths) equal to 8 metres
(25 feet) for the first sensor and 16 metres
(50 feet) for each subsequent sensor when
used on the TraceTek TTDM or TTSIM-1/1A/2
alarm & locator panels.
If sensors are used alone on a circuit, without
sensing cable, the ‘zones’ setting within ‘units’
can be used on the panels.
Power Supply
Each OPSEN requires a 12Vdc power supply. Power is available from
a separate power supply unit: AT-PSU-1 for 1 to 10 sensors.
The 12Vdc should be connected as detailed below, care should be
taken when connecting the power as the sensor is polarity sensitive.
The Bulk OPSEN cable is colour coded for connection into the
TraceTek and AquiTron™ panels: white 12Vdc (+) and blue OV (-)
should be used for the power cables.
Power indication
The sensor unit is provided with a GREEN LED to indicate power
present.
Alarm indication
In the event of a leak being detected the units RED LED will
illuminate.
Indication will also be displayed on the following leak detection
panels:
AT-SZA, single zone indication.
AT-DIM, single zone indication.
AT-MZA, individual zone indication.
TTDM, distance or zone number/region/area name.
TTSIM-1/1A/2, via the master panel or BMS a distance or zone
number/region/area name is available.
Detection time
The Optical sensor head will detect the presence of a liquid within
seconds of it making contact. The alarm activation on the OPSEN
(Red LED) will be immediate, however, alarm indication on the leak
detection control panel will depend on the model selected.
Application Liquids
The OPSEN has been designed for use with hydrocarbon based
liquids such as fuels and oils. The sensor will also detect other none
aggressive liquids.
The OPSEN optical sensor head will also detect water and many
other chemicals.
For further liquids please contact your distributor.
