Kidde Alarmline LWM-1, SenseTek introduces the linear thermal detection system. The system comprises of a controller unit and your choice of the length of the sensor cable. The Kidde Alarmline thermal detection system does not only warn you at a maximum alarm temperature, but also when there is a fast increase in temperature (rate of rise) so that a fast detection is guaranteed.

The Kidde Alarmline system is completely programmable with DIL switches, without the need for a laptop computer. This means a very rapid commisioning period. The Alarmline system meets the standards of detector rating A1, A2, B, C and P. Because of the EN54-5: 2000 certification the system can be used in certified fire alarm systems.

The specifications for the Alarmline thermal detection system are:

  • Can be installed up to 7.5 meters.
  • Maximum cable length of 300 metres within EN54-5 specifications
  • 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 Digital is a twin conductor cable with temperature sensitive insulation protecting the inner conductors. Alarmline Digital operates by melting the internal insulation at a predetermined temperature, this results in the conductors short circuiting which provides a fire alarm signal. Fire and Fault conditions are provided by continuously monitoring for a short circuit (Fire) or an open circuit (Fault) state by the fire alarm panel.
