  1. Intelligent Detection Systems Benefits of intelligent detection systems include: • integrity of system confirmed continuously • pre-alarm facility • high flexibility of system configuration • performance log for each detector • condition check for ease of maintenance • verification of alarm levels

  2. Context Plus – Advanced Features • alarm flag for fast response/location of detection • protocol parity bit for basic error checking • alarm interrupt for prioritised MCP response/location • addressing with patented XPERT card • electronics-free base • pure digital protocol transmission • return device address for integrity check

  3. Context Plus – Advanced Features • low-profile design • pure white finish • high environmental performance • polarity insensitive • no insect-related alarms • easy to install • smooth action detector base • Polished finish - easy to clean • meets approvals world-wide

  4. Reliable Detection Ionisation Smoke Detector Optical Smoke Detector Heat (standard) Detector Heat (high temp) Detector Multisensor Detector

  5. Digital count Fire Pre-alarm Normal 55 45 8 Fault 0 Control Panel Response Thresholds

  6. Interfaces Input/output unit (with bi-directional isolator) Sounder control unit (with bi-directional isolator) Switch monitor (with bi-directional isolator) Zone monitor (with bi-directional isolator)

  7. Switch Monitor • monitored input for pre-alarm, alarm and fault conditions • monitoring for open/short circuit faults in contact wiring • red/yellow LED indication for input status (fire/fault) • Switch Monitor Plus has ‘delay’ and ‘reset’ facilities • built-in bi-directional short circuit isolator

  8. Switch Monitor

  9. Zone Monitor • loop-powered • head removal monitoring allows zones of detectors and MCP’s • compatible with intrinsically safe devices • built-in bi-directional short circuit isolator

  10. Zone Monitor Unit

  11. Input/Output Unit • loop-powered • monitored input for normal, alarm for fault conditions • additional non-monitored opto-isolated input • red LED indication for energised relay • red/yellow LED indication for input status (fire/fault) • built-in bi-directional short circuit isolator

  12. Input/Output Unit

  13. Sounder Control Unit • each module monitors and controls one sounder circuit • continuous or pulsed sounder circuit operation • pulsing of sounder circuits can be synchronised • group control address facility available • red/yellow LED indication for sounder circuit energised/fault conditions • monitoring of local PSU available • built-in bi-directional short circuit isolator

  14. Sounder Control Unit

  15. Quality Product Testing Robust designs to withstand transportation, handling and life-cycle • EMC – radiated immunity, conducted immunity, transient bursts, surges & electro static discharge • environmental – elevated/cyclic humidity & high/low temperatures • corrosion – sulphur dioxide & saline spray • mechanical stress, impact, shock & vibration Over-testing is conducted to exceed international standards
