3 Basic System d-LIST SEC 15 and SCU 800

4 SCU 800 Memory for lists Volatile Timer None – Timer (volatile)
Housing Aluminum Diecast Housing Power supply 24 V DC Displays LEDs Processors 1 Memory for lists Volatile Timer None – Timer (volatile) Interfaces 1 (RS232 or RS485) Cablellength 2x 250 m (incl. connection line) Sensors 2x 99 Groups 64 Grouprelays 16 Redundance/ Loop No

5 Cabledesign SEC 15 Cable jacket Aluminum shield Filler material Sensor
Flat ribbon cable Strain relief

6 SEC 15 2- wires Sensorcabel weight 0,35 kg/m Connection
Cable design 2- wires Sensor distance min. 0,25 Meter Standard distances 1, 2, 3, 4 and 5 m Measuring range -40 °C to 85 °C; short term 120 °C Sensorcabel weight 0,35 kg/m Connection Up to two single sensorcables can be connected to the Control - and Evaluationunit SCU 800 Installation with sepparate connectionbox possible as well. Connection boxes CBO 5 ESD / CBO 5 SEC

7 Imprint – Address – Sensornuber
Address (fix) Logical sensor number (Programmable)

8 SEC 15 - Imprints Cablenumber yyy = Serial number zz = Sensor distance
3-digit Measuring point imprint Imprint 1: Imprint 2: Imprint 1 Imprint 2 180 °

9 Measuring cycle Measurement Reading Temperatures Test Evaluation
Alarm? Set alarmrelay Output of protocol

10 Addressing / Data reception

11 Addressing - Advantages
Branchable Bidirectional No termination necessary Free numbering System with different sensordistances possible Usage of external sensors

12 Test - Plausibility Validity of temperatures Temperature jumps

13 Alarmevaluation: Maximum temperature alarm
SCU 800 (EN 54-5:2001: Responseclass A1) Message Standard value Scope Pre signal Warning max. 90% of maximum - threshold value Device Alarm Fire alarm! 50°C Group

14 Alarmevaluation: Referenceprofile Referencevalue Adjustment / Sensors with ambient temperatures without quick temperature fluctuations. Temperature (°C) Measuring Cycle Current temperature Reference temperature

15 Alarmevaluation: Difference temperature alarm Quick rise of environmental temperature leads to Difference-temperature alarm. - Reference Temp. - Current Temp. Presignal HEATING Alarm  FIRE! - DT

16 Alarmevaluation: Difference temperature-Alarm
SCU 800 (EN 54-5:2001: Responseclass A1) Message Standard value Scope Presignal T-increase 50% of Difference temperature threshold Device Alarm Fire alarm 2,8 K Group

17 Maximum Differencetemperatures
Help for the adjustment of the Difference temperature thresholds One table per section Maximum 8 entries per table With a simultaneous increase of several differencetemperatures in a section, only the highest value is entered

18 Alarmevaluation Responsetime (EN54-5, Class A1) (SCU 800)
Rise of airtemperature Lower Threshold Upper Threshold 1 K / min 29 m 00 s 40 m 20 s 3 K / min 07 m 13 s 13 m 40 s 5 K / min 04 m 09 s 08 m 20 s 10 K / min 01 m 00 s 04 m 20 s 20 K / min 00 m 30 s 02 m 20 s 30 K / min 00 m 20 s 01 m 40 s

19 Frostalarm evaluation
SCU 800 Information Standardvalue Scope Presinal Frost warning 5°C above Frostalarmthreshold Device Alarm Frost alarm -40.0°C (no evaluation) Group

20 Connectionboxes for SEC 15
Size: mm x 130 mm Protection class: IP66 Material: Polycarbonate, red cover Accessory kit: Closing caps, fittings, installation instructions CBO 5-SEC CBO 5-ESD-T

21 Installation parts Polyamid cable clip CLIC 15

22 Installation with wireties
SEC 15: FEMC Polyamid wireties for rope installation (Length 270 mm)

23 Installation Stainless steel bracket with striker: SEC15: MDC 15
Stainless steel bracket (Wst , metal sheet thickness 1,5 mm) SEC 15: MDJ 15 SEC 15: MDJ 15 S Stainless steel wireties (201 mm) MDC MDJ

24 Signalisation: Collective relays
Alarmtype SCU SCU 800/16 Firealarm 1 Presignal Frostalarm Fault 1Per Sensorcableconnection or with additional pcb, one output for Alarm and fault

25 Signalisation: Grouprelays
Alarmtype SCU SCU 800/16 Firealarm Presignal Frostalarm Fault

26 Signalisation: Relays
Relay outputs are codable via jumpers / resistors Normally open contact (NO) Normally closed contact (NC) For closed current supervision

27 Signalisation: Interfaces
SCU 800 RS232 1 RS485 LAN (Ethernet) USB 1One serial: either usable as RS232 or RS485.

28 Signalisation: Protocols
SCU 800 Modbus TCP Modbus (Seriell)1 1 IEC LIST2 3964R 1RS232 or RS485 2LISTgraph II Visualisation, Master / Slave communication
