Sinteso S-LINE fire detectors

S-LINE detectors for sophisticated applications

S-LINE intelligent detectors are the ultimate when it comes to fast response and false alarm resistance. Using Siemens' innovative ASAtechnology™ they provide exceptional detection response to a wide range of fire types. The special signal analysis process employed by S-LINE fire detectors is very reliable in preventing false alarms caused by deceptive on-site phenomena, such as:

  • Machine exhaust gases

  • Industrial dust

  • Steam

Customizable protection in any environment

> ASA neural fire detector FDOOTC241

- Detection properties same as FDOOT241-A, plus earliest possible detection of fires producing CO

- Highest immunity with highest sensitivity

- 2 optical

- 2 heat

- 1 carbon monoxide

> ASA neural fire detector FDOOT241-A

- Early detection of flaming fires involving solid and liquid materials and of smoldering fires

- The simultaneous analysis of smoke density and temperature in combination with ASAtechnology signal evaluation increases the protection against deceptive phenomena such as dust and steam

- 2 optical

- 2 heat

> ASA wide spectrum smoke detector FDO241

- Early detection of smoke-forming smoldering and flaming fires

- Operating according to the scattered light principle with a sensor for optical forward scatter

- Like the FDOOT241-A, its opto-electronic sampling chamber keeps out extraneous light while optimally recognizing smoke particles

- 1 optical

> ASA heat detector FDT241

- Detection of open flames and fires accompanied by a rapid rise in temperature

- The heat detector measures the ambient temperature and the temperature inside the detector housing, so that it can instantly detect an increase in temperature

- 2 redundant temperature sensors can be used either as a differential heat detector or as a maximum heat detector

- 2 heat

> FDF241-9 flame detector

- Detects smokeless liquid, gas fires and smoke forming open fires arising from the burning of materials containing carbon

- For highest application requirements (inside and outside)

- 3 infrared sensors

> FDL241-9 linear smoke detector

Early detection of smoke-forming flaming fires e.g. in:

- Warehouses

- Halls with complex ceiling structures

- Factory halls

- Sensor and reciever in 1 housing
