WHAT IS CBL’S LINEAR HEAT
DETECTION
• Temperature detection in
the form of a continuous
cable.
• A sealed cable structure
and high temperature
resolution enables early
fire detection, even in
areas with a high
accumulation of dirt, fog,
ice and vibration.
• Mechanically allows
installation at point of
risk.
LIST SENSOR CABLE
• An early warning temperature detector.
• For applications where ,due to critical environmental
conditions, conventional detectors can only be
implemented to a limited extent or not at all.
• An intelligent hybrid censoring cable that can pinpoint to
the meter where the temperature variations have occurred.
• The cable operating temperature is – 40°C to + 85°C
range (for short periods +200°C) with a temperature
resolution of 0.1°.
DETECTION
• Differential detection.
• Absolute alarm detection.
• Low temperature detection.
• Grouping of sensors into zones by programming
• Independent thresholds for each zone (resolution 0.1°)
• Registration of the max. differential temperature per zone
LIST SENSOR CABLE SYSTEM
• The list system can be installed in conjunction with a
conventional fire system.
• Highly sensitive external sensors can be added.
• List system is a temperature measuring and fire detection
system based on a sensor cable,which measures
temperature along its length, up to 2.5km with a high
resolution, thus enabling sensitive and reliable monitoring
under harsh environmental conditions.
• Application examples are illustrated.
TUNNELS
• Road, Subways, Railways.
• Maintenance free system
• Insensitive to exhaust
fumes,salts,humidity and
vibration.
• Exact location of fire.
• Easy installation in new and
existing tunnels.
• Monitoring of connection
tunnels.
RAILWAY HANGERS
• Railway,sub-way and bus
marshalling yards.
• Insensitive to weather
influences.
• Easy installation.
• Maintenance free system.
• Exact localisation of fires.
• Adjustable alarm
thresholds.
POWER STATIONS AND
SHIPPING
• Cable trays, double floors,
suspended ceilings.
• Fire detection in
inaccessible areas .
• Fire detection on parking
decks of ferries.
• Protection for important
energy and data cables.
• Alarms given on
overheating cables.
• Exact localisation of
overheating cables.
• Turbine bearing housings.
BELT CONVEYORS
• Power stations, chemical
industry,fodder industry.
• Insensitive to dirt.
• Detection of overheated
idlers.
• Monitoring of delivery
points.
• Monitoring of belt-drivers
with additional sensors.
INDUSTRIAL PLANTS
• Petroleum depots.
• Petrol transporters filling
stations.
• Cold storage houses.
• Food preparation areas.
• Coffee roasters.
• Composting plants.
• Spray painting facilities.
• Fodder dehydrators.
• Historical buildings.
BUILDINGS AND MULTISTOREY CAR PARKS
• Early warning temperature
detection system.
• Communication rooms.
• Monitoring of critical
cables in inaccessible
areas.
• Car parks.
• Saves valuable time with
exact localisation of
temperature variation.
• Lift shafts and escalators
protection.
SENSOR CABLE SEC 15
• The temperature data transmission is made in digital code.
• Maximum cable lengths of 2 x 250m per control unit.
• The SEC 15 cable consists of a 2 core flat cable, with
integrated temperature sensor circuits fixed in user
definable distances.
SEC 15 CABLE

• Operating range temp
-40°C … +85°C
(short periods)
max. +100°C
• Resolution

• Measuring cycle
10 seconds
• Diameter
13 mm
• Bending radius
min. 20 cm
• Cable length
2 x 250m per SCU
• Marking
each sensor
• Halogen free jacket
• FRNC jacket (flame retardant, non-corrosive)
SENSOR CABLE SEC 20
• The SEC 20 cable consists of a 4 core flat cable, with
sensors mounted at predetermined intervals 1, 2, 4 or
8 meters.
• The sensors contain an ASIC, which is a user specific
circuit, and a semiconductor temperature sensor.
• In both cases, the application determines the distance
between measuring points (sensors).
• The cable can also be branched according to the
application. Measuring points have fixed addresses,
therefore enabling their physical location.
