SenseTek is your supplier of the Alarmline LWM-1 thermal cable detection systems. A distinction can be made between analog self-resetting systems and digital systems.

Analog systems use a controller that provides alarm transmission of the connected sensor cable. The sensitivity of the system can be programmed into the controller by means of a PC. Digital systems can be used with or without a controller. The systems work as a fusing cable where the two wires melt together when the alarm temperature is reached. When a digital cable is connected to a controller, a system is created that shows where the cable has been fused, in other words where the fire alarm has been.

The analog Alarmline system has an EN54-22 certificate and can therefore be used in certified fire alarm systems. It is necessary, however, to agree on an adapted fire size, since the standard Dutch test fire 7 does not generate sufficient heat to allow the system to react within the combustion time. Digital cable systems with alarm temperatures of 78°C and 88°C are EN54-28 certified. The other alarm temperatures are not yet available with an EN54-28 certificate.

The specifications for the Alarmline thermal detection system are:

    • Can be installed up to 7.5 meters.
    • Unlikely of false alarms even in polluted areas
    • Sensor cable is easy to install
    • Special coated sensor cable for durability
    • Controller can be installed up to 500 meters from the sensor cable
    • Easy to maintain system
  • Can be installed in explosive environments

Alarmline cable and its associated controllers allow integration with many fire alarm and extinguishing control systems offering a complete system solution. The use of ATEX approved junction boxes and Intrinsically Safe barriers enable the Alarmline system to be used in hazardous areas.

Alarmline LWM-1

Alarmline systems have been on the market for many years. The LWM-1 system in particular has been widely used in the past 20 years. Such installations are therefore still in use at many locations worldwide. For maintenance on LWM-1 systems and for replacement of system parts, SenseTek can still supply Alarmline LWM-1 parts.
