ALARM AND SECURITY
Applications
Fire alarm systems
Monitoring of firedoors (e.g. on ships)
Monitoring of security fences
Prison security and alarms
Factory machine alarms
Alarm monitoring on conveyor systems (e.g. mines and
tunnels)
Monitoring of emergency lighting
Control of CCTV cameras
Specific tasks
Monitoring of smoke detectors
Temperature measurement
Detection of firedoors open/closed through limit
switches or magnets
Detection of doors/windows open/closed
Monitoring of sensors on security fences
Transmission of alarms from machine monitoring
devices to a central location
Monitoring of pull–cord switches and conveyor belt
alarm signals with exact position indication
(e.g. mines and tunnels)
Frequent checking of emergency light operation and
reporting to central location
Dupline
®
key benefits
Bus–powered small–sized input modules and sensors
like inductive, magnet proximity, PIR and temperature
makes installation cost–effective, fast and flexible
Steep learning curve when electricians are trained to
install and maintain systems
Free topology provides easy and flexible installation
Noise–immune, robust and well–proven system
Simple point–to–point transfer of signals is easy to make
Use of existing wiring reduces cost
Transfer of alarm signals over long distances
Easy to expand and change the installed system
TRAFFIC SYSTEMS
Applications
Monitoring of alarm signals from railway crossings and
reporting to central location.
Control and monitoring of trackshifter heating.
Control of railway tunnel ventilation.
Remote control of unmanned railway stations.
Control and monitoring of emergency generators in airports.
Control and monitoring of taxi and runway lights in
airports.
Specific tasks
MGathering of alarmsignals over long distances (seve-
ral kilometers)
Measurement of trackshifter temperatures
Measurment of environmental temperature and humidity
Open/close gas valves
Firing of gas heater
Measurement of gasconcentration
ON/OFF switching of lights and ventilators over long
distances
Monitoring of the status of runway lights and announ-
ciate alarms to control tower
Dupline
®
key benefits
Dupline
®
can transmit up to 10 km without a repeater
There is no limit to the transmission distance when
repeaters are cascaded
Existing wires can be used for Dupline
®
and can run in
the same cable conduit as the power
It is easy to engineer, install and maintain the installa-
tion due to the straight forward and flexible nature of
Dupline
®
Dupline
®
solves the combination of long distance
transmission and high distribution of I/O’s in an econo-
mical way
