IEC 60079-11 Ex Group: IIC 2 Smoke Detection Panels SDS-4, SDS-8, SDS-16 and Extension Units SDS-E8, SDS-E12, SDS-E16, SDS-EC16 2.1 System Description A block diagram of the SDS-48 including earting points will be shown in drawing SDS-48-Ex-1.tcd (see appendix). The smoke detection panels exist of 2 self-contained functional areas, the detection unit and the evaluation unit. The detection unit will be penetrated by hazardous atmosphere. The evaluation unit is separated from the detection unit and will not be penetrated by hazardous atmosphere. The extension panels are compound only of detection units. Every detection unit contains one intrinsically safe circuit with max. 8 smoke detectors type XP95 I.S. 55000-640, the same number of airflow indicators type 605 and one Detector Connection Module with max. 8 resistors 1KOhm 3 Watt. The evaluation unit and the detection units contain the following components: Galvanic Isolators KHD0-CS 1.54 and/or KHD0-CS 2.54 Smoke Detector XP95 I.S. Pressure Switch Type 605.99622 Resistor R1 1KΏ / 3W Resistor R2 22KΏ / 1W A circuit diagram of the intrinsically safe circuits will be shown in drawing SDS-48-Ex-2.tcd (see appendix).

safetec 2.2.2 Max. Temperature Rise in Resistors under Fault Conditions The resistors, which are integrated into the circuit, are simple apparatus according IEC 60079-11 clause 5.7. They do not add any capacitors or inductances. The resistors are small parts with a surface area smaller than 1000 mm², which allows a maximum temperature of 150 C for T5 (IEC 60079-0:2007 clause 5.6.2). R1: Resistor 1K Ω surface area: ~ 275 mm² (< 1000 mm²) rated power dissipation: 3 W max. power supply from isolator: 0,653 W temperature rise at 1W power dissipation: 120 K (see datasheet) temperature rise at 0,653 W: 78,4 K max. environment temperature: 45 C max. temperature rise at 0,653 W: 123,4 C (< 150 C) R2: Resistor 22KΩ surface area: rated power dissipation: max. power dissipation: thermal resistance temperature rise at 0,036 W: < 1000 mm² 1 W 28V*28V/22KΩ= 0,036 W 108 K/W ~4 K 3 Fan Unit SDS-M0440 / SDS-M0441 The fan unit SDS-M0440/SDS-M0441 is protected by method c (constructional safety).
