Description

Addressable Analog Heat Detector with a Thermal Sensor – FAH-425-T-R Bosch

Addressable manually and automatically.
AVENAR detector 4000 is a new range of automatic fire detectors that offer extraordinary precision and speed of detection.
Models with two optical sensors (double optic) are able to detect the slightest presence of smoke.
The range consists of models with swivel, with manual and automatic addressing, and models without swivels with automatic steering setting.
Sensor technology and signal processing. Individual sensors can be configured in the FSP-5000-RPS programming software.
All sensor signals are continuously analyzed by the internal evaluation electronics (Intelligent Signal Processing, ISP) and are linked together by an integrated microprocessor.
The link between the sensors means that the combination detectors can also be used where some smoke is expected, steam or dust during the course of normal operation.
The alarm is only triggered automatically if the combination of signals corresponds to the characteristics of the location field, selected when programming.
Consequently, the number of false alarms is lower., the duration of the sensor signals is analyzed after the detection of fires and faults, it remains as the place for higher detection reliability for each individual sensor.
In the case of the optical and chemical sensor, the response threshold (trend compensation) actively adjusts.
Manual or timed deactivation of individual sensors is possible for adjustment to extreme interference factors.
AVENAR detector 4000 offers all the features of LSN improved technology:

• Flexible network structures, including T-tap without additional elements (non-swiveling T-tap on models without swivels)

• Until 254 LSN improved elements per loop or branch line

• Manual or automatic addressing of the detector, with or without automatic detection

• Power supply for components connected via LSN bus

• Unprotected fire detection cable can be used

• Cable length up to 3.000 m (con LSN 1500 A)

• Backward compatibility with existing LSN systems and central units

• Control of the electromagnetic impact in the environment to carry out the rapid analysis of the causes (EMC values ​​are displayed on the control panel) What's more, the range offers all the advantages of LSN technology.

Control panel programming software can be used to change detection characteristics based on room usage.
