1. DECENTRALISED CONTROL SYSTEM BY EK ENGINEERING WWW.EKEINDIA.COM E: INDIA.EKE@GMAIL.COM MOBILE: +91-96809 66000 (INDIA)

2. TYPE OF CONTROLLER ARCHITECTURE: Centralised control system Only one controller located at centralised area All sensors, transmitter connect to this controller via digital bus or analog circuit. Digital output or control command will be given by the controller, hence each control cable will originate from this centralised controller. Require large space for bigger control system High cable cost WWW.EKEINDIA.COM E: INDIA.EKE@GMAIL.COM MOBILE: +91-96809 66000 (INDIA)

3. CENTRALISED SYSTEM ARCHITECTURE: 3 S1 Control Unit / Panel Control Room / Area S = CO, NO, NO2, SO2 sensor (multi or single detector) Communication cable: 2 x 2-core twisted, shielded cable S2 S6 S7 S5 S8 Sn S4 S3 To BMS / SCADA Fire Alarm System Fan MCC panel (and VFD panel) WWW.EKEINDIA.COM E: INDIA.EKE@GMAIL.COM MOBILE: +91-96809 66000 (INDIA)

4. TYPE OF CONTROLLER ARCHITECTURE: De-Centralised control system (Staggered architecture) Based on Master – Slave architecture Master controller is installed at central space, while slave modules are installed in staggered manner at sensor / transmitter Zone areas Communication cable will connect all slave to Master, hence to/fro communication will happen between master and slove controller All sensors in the zone will connect to slave controller of the zone via digital communication bus or analog circuit Control cable will originate from Zone Slave centralised controller, thus low cable cost Suitable to handle high number of sensors / transmitters WWW.EKEINDIA.COM E: INDIA.EKE@GMAIL.COM MOBILE: +91-96809 66000 (INDIA)
