Harsh environments –
for example in industry, with frequent deceptive environmental phenomena such as dust, steam or welding fumes.

Moderate environments – such as office buildings and shopping centers, with average risk to people and occasional deceptive environmental phenomena.

Clean environments – such as server rooms or patient rooms, where the top priority is protection of people and data.

ASA neural fire detector FDOOTC241

- Detection properties same as FDOOT241-9, plus earliest possible detection of fires producing CO
- Highest immunity with highest sensitivity

- 2 optical
- 2 heat
- 1 carbon monoxide

ASA neural fire detector FDOOT241-9

- 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 FDOOT241-9, 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
