Detection and extinguishing

The heart is a tube-shaped linear fire sensor named Lifdes™ (Linear fire detection source). This patented sensor, produced with a high-molecular polymer, is stressed by a pressure of 15 bar. Connected to a fire extinguishing bottle via a valve, it is permanently under this pressure and will burst if its ambient temperature rises above 110°C. In this way, it acts like a linear sensor that will always be activated right where the activation temperature has been reached first. Practically at the same time as the pressure drops in the burst Lifdes sensor, the valve of the bottle will be opened and the machine is switched to “EMERGENCY STOP”. The extinguishing agent is introduced via a separate extinguishing line and appropriately arranged extinguishing nozzles. The system requires no external power for the detection and extinguishing of fire. This happens pneumatically, and is therefore insensitive to all kinds of technical interferences. Incorrect activation of the system is virtually impossible.

Measurement

The Sinorix al-deco STD object protection system measures the quantity of the extinguishing agent online, monitors the pressure of the detection line, the operating as well as the main power status. The interface displays all functions optically/acoustically, for example an alarm is activated when the loss of extinguishing agent exceeds 20% as well as in case of a fire incident. In case of a power outage, the functions of the interface will be held up by means of a battery. The system can be reset in a controlled manner with the key switch. Therefore, it is possible to instantly put the machine tools into operation again after a fire incident. However, the fact that the Sinorix al-deco STD object protection system is not yet operational will be clearly communicated and recorded.

Alarming

An alarm is given either optically/acoustically (fire alarm) or through the interface. A connection to an existing fire control panel is possible. Additional signals such as loss of extinguishing agent, ON/OFF of the extinguishing system, fire alarm etc. can be used via potential-free contacts for other applications as well.

Maintenance and recommissioning

The maintenance of the system is displayed electronically and can be carried out, just as a recommissioning after a fire incident, by the operator himself - with the help of the corresponding documentation if required. The extinguishing agent containers are fitted with a special filling adaptor and can be refilled from any gas refilling station.
