Fire detection:

KIDDE-DEUGRA detectors in the engine room help detect fires:

In the case of a fire and/or overheating, the detectors send alarm signals to the control unit and automatically trigger the fire fighting process. Point detectors or linear sensors serve as detectors.

They not only report a fire, but also when the fire has been extinguished. All detectors, of course, are operational again after the successful fire fighting.

Line detectors:
FIREWIRE is the fire warning wire in the form of a stainless steel capillary with coaxially seated electrode. At an increase of temperature, both the resistance and capacity changes. If a certain threshold value is exceeded, the linear detector triggers the fire fighting system. The FIREWIRE may be installed in the area to be protected in such a way that it continuously covers the entire room.

FIREWIRE: The temperature detector, which is produced in standard lengths of 150 cm to 600 cm. By means of special couplings, FIREWIRE elements can be interconnected up to a length of 30 m.

Point detector:

Mechanical point detectors.

Mechanical point detectors operate according to the principle of specific thermal expansion: If a fixed temperature is exceeded, they transmit a triggering signal to the respective control unit. After the fire-extinguishing process, the point detectors simply reset.

Electronic Point Detector

DTF detectors essentially are nothing but extremely fast-responding NTC resistors. They have an extremely robust housing to protect against water and mechanical damage.  
 In practice: The alarm temperature can be set by means of corresponding software individually in the control unit.

Safety: The mechanical mounting and electrical connection is simple and safe via a plug connection according to VG 95234.
