Product Description

The FCP-320/FCH-320 Conventional Automatic Fire Detectors works on the basis of the 

conventional technology and combines standard detection methods such as scattered light 

measurement and temperature measurement with gas measuring technology at the highest 

configuration level.

This method uses state-of-the-art processing methods to evaluate the signals from the gas 

sensor and scattered light sensor or thermal sensor.

Security against false alarms is thus increased significantly and detection time is reduced in 

comparison with the fire detectors generally available on the market today.

Thanks to the higher information content of the multisensor detectors, the use of detectors is 

possible in environments where pure smoke detectors cannot be used.

The detectors are available in the following configuration levels:

–

FCP-OC320: Combined optical, gas-sensitive smoke detectors

–

FCP-OT320: Combined optical, thermal smoke detectors

–

FCP-O320: Optical smoke detectors

–

FCH-T320: Thermal detectors.

The detector's timeless and innovative design is a result of the cooperation between 

engineers and designers. With this design it is possible to reconcile the contradictory goals of 

a generous installation space and a small detector.

The placement of the individual display on the detector tip is the first externally visible 

characteristic of the installation-friendly development concept. The stable and robust 

detector base need no longer be aligned due to the position-independent position of the 

individual display.

It is suitable for surface and flush mounting and includes separate mounting points for 

dropped ceiling and concealed sockets. In addition, it fits all common bore patterns. For 

surface mounting, the cable may be fed through on the side. 

The integrated strain relief for interfloor cables prevents the removal of cables from the 

terminal after installation. The terminals are easily accessible; a retainer for the end of line 

resistor is integrated. Cable diameters of up to 2.5 mm

2

 can be used.

It can be equipped with a damp room seal so that all installation requirements can be covered 

with one base.

The 320 Series detectors are available with either a 420 Ω alarm resistor or a 320 Ω alarm 

resistor. The operating voltage range is 8.5 V DC to 32 V DC, which allows the detectors to be 

used with almost every common conventional fire panel.
