d-LIST System

The maintenance-free sensor cable SEC 15 is the central sensor element of our resettable linear heat detector d-LIST. The sensors are fully shielded against environmental influences and operate reliably in a temperature range from -40 °C to +85 °C (it can also resist short-term heat up to +120 °C). Depending on the project requirements, the sensor distances can be freely selected between 0.5m and 10m. With the help of connection boxes, it is also possible to branch the sensor cable routes.

The evaluation of the measured temperatures takes place in the d-LISTcontroller evaluation unit. The intelligent evaluation algorithms avoid unfailing false alarms. Up to 32 programmable sections enable alarm and fault messages to be forwarded to external systems via protocol. The wear-free components guarantee a long service life. In addition, the evaluation unit is RoHS-compliant and features low power consumption.

The housing of our connection box CBO 15 is made of glass-fibre reinforced polycarbonate, is UV and weather resistant and free of halogens, heavy metals, PVC and silicones. Up to two SEC 15 sensor cables can be injected into the connection box, and a combination with other individual sensors is also possible. The connection box can withstand a temperature range of -35 °C to +60 °C.

Our ESD-A5 single sensors have proven themselves many times over in their high resistance to corrosion, pitting and a variety of chemicals. Not at least thanks to the heat-conductive potting compound, which ensures a hermetic seal. The maximum number of individual sensors per sensor cable connection A / B to SCU 800 or d-LISTcontroller contributes up to 50 individual sensors with a total cable length of 100 m and 51 to 99 individual sensors with a total cable length of 50 m.

For training and demonstration purposes, we have developed a simulator for the d-LIST system. With the SEC 15 simulator CSM 30, up to 31 sensors can be simulated; this also includes fault simulation by switching off one of two sensors that can be activated. as well as alarm simulation by manual heating at the 30 sensor markings.

Our SECcon 15 pre-assembly, which is individually tailored to the respective project requirement, enables easy installation and commissioning of our SEC 15 sensor cables and CC 15 connecting cables by means of plug connectors. The mechanical coding of plug and socket ensures correct polarity reversal. This means that neither special tools nor special knowledge are required on site and the duration of installation and commissioning is drastically reduced.

The two universal connection modules establish the connection between the sensor cable, the individual sensors and the connection cable. The universal connection module UCM 15-SEC is suitable for the connection box CBO 15-SEC and enables connection of up to two sensor cables SEC 15. The universal connection module UCM 15-ESD belongs to the connection box CBO 15-ESD and enables the connection of one sensor cable SEC 15 in combination with up to four individual sensors ESD-A5, or of up to eight individual sensors ESD-A5, as required.

With our linear heat detector d-LIST, the open data protocols enable direct communication with external systems (FACP and/or PLC). The Modbus RTU protocol is transmitted via serial RS232 or RS485 interfaces.
