3 Basic LIST system SEC 20, CBO and LISTcontroller

4 LISTcontroller 19“ 1U rack Non-volatile Timer LISTcontroller Housing
Power supply 24 V DC Displays LEDs, LCD Processors 3 Memory for lists Non-volatile Timer RTC (Goldcap) Interfaces 4 (2x RS232, RS485, LAN) Cable lengths 3.200 m (+ max. 300 m connection line) Sensors 320 Groups 254 Group relays 256 Redundance / Loop Yes 4

5 Cable design SEC 20 Cable jacket Aluminum shield Filler material
Sensor Flexible flat cable Strain relief 5

6 SEC 20 SEC 20 4 wires min. 0,5 meter -40 °C to 85 °C
Cable design 4 wires Sensor spacing min. 0,5 meter Standard spacing 2, 4, 5, 8 and 10 m Measuring range -40 °C to 85 °C Sensor cable weight 0,45 kg/m Connection At the beginning of each single sensor cable , a connection box shal be provided, in which the connectioncable connects the Listcontroller to the sensorcable via CCM connection module. Connection boxes CBO 20 6

10 Addressing / Data reception SEC 20
Digital addressing Analog data 10

11 Addressing - Advantages
Branchable Bidirectional No termination necessary Free numbering System with different sensor distances possible 11

12 Test - Plausibility Validity of temperatures Temperature jumps 12

13 Alarm evaluation: Maximum temperature alarm
LISTcontroller (FprEN 54-22:2012: Response class A1N and A2N) Message Standard value Scope Pre- signal Warning max. 90% of maximum - threshold value Device Alarm Firealarm! 55°C Group LISTcontroller (FprEN 54-22:2012: Response class BN) Message Standard value Scope Pre- signal Warning max. 90% of maximum - threshold value Device Alarm Firealarm! 70°C Group 13

14 Alarm evaluation: Reference profile Reference value adjustment / sensor for ambient temperatures with normal temperature development. Temperature (°C) Measuring Cycle Current temperature Reference temperature 14

15 Alarm evaluation: Differential temperature alarm Quick rise of environmental temperature leads to differential temperature alarm. - Reference Temp. - Current Temp. Pre-signal HEATING Alarm  FIRE! - DT 15

16 Alarm evaluation: Differential temperature alarm
LISTcontroller (FprEN 54-22:2012: Responseclass A1N, A2N and BN) Message Standard value GScope Pre signal T-increase 50% of Difference temperature threshold Device Alarm Fire alarm 2,5 K Group 16

17 Maximum Differential temperatures
Help for the adjustment of the Difference temperature thresholds One table per section/group Maximum 8 entries per table With a simultaneous increase of several differential temperatures in a section, only the highest value is recorded One Table per section (group), helps for the manual, later adjustment of the diff value, if there are false alarms 17
