Anatomy of a Control System Anatomy • Brains – decision making control panel • Eyes/ears – Sensors and detectors • Central nervous system – cable network • Cardiovascular System – Power supplies • Muscles – Power switching panels (MCCs) Minimise single points of failure Protect critical functions Provide early warning and contingency planning Defined failure modes “Peoplefeelbetterinin.

Anatomy of a Control System Controls: Should be Application Specific – fire alarm systems are not always appropriate as life safety control systems Should be designed with resilience, backup and reliability Not BMS, BAS or HVAC/process control systems • Open/Closed Protocol? • Only operate on first activation (subsequent signals are locked out) • Key enabled Firefighters override “Peoplefeelbetterinin.

Anatomy of a Control System Brains - Decision making system OPV Panel • Controls the whole system • Makes decisions based on a programmed cause and effect • Displays the status of the system • Allows the system to be overridden • pr. EN 12101 -9 “Peoplefeelbetterinin. Coltconditions” | |www. coltgroup. com www. coltinfo. co. uk

Anatomy of a Control System 230 Vac Supply Expandable modular system to suit the needs of the project “Peoplefeelbetterinin. Coltconditions” | |www. coltgroup. com www. coltinfo. co. uk

Anatomy of a Control System OPV Control System • Bespoke/unique design for smoke control - the system design is tailored specifically to this application • Configurable failsafe operation of the system – continues to operate in its last known start on loss of comms • Configurable failsafe operation of individual vents and dampers, should the control panel, or the network connection from the panel, fail. • Watchdog timers in all nodes (including sensors and control panels), to detect malfunctions or loss of data. • Error detection and correction on all data links. • Programmable CAE, with full boolean logic, allows for complex control algorithms and interactions, far more so than a fire alarm system. “Peoplefeelbetterinin. Coltconditions” | |www. coltgroup. com www. coltinfo. co. uk

Anatomy of a Control System OPV Control System • Allows devices within a zone to be in different states, according to device type and CAE. • Allows for active closed as well as active open states (fire alarm systems typically only have active and standby states) • 8 level priority system provides comprehensive prioritization of control • Multiple thresholds per sensor allows various control states according to circumstances. • Provides non-fire operation of vents and dampers, for day-to-day ventilation and air control. “Peoplefeelbetterinin.

Anatomy of a Control System Sensors and detectors Any Apollo addressable device can sit on the network: Smoke Detectors Heat Detectors Manual Call Points Override Switches I/O devices - allow switching of up to 3 24 Vdc or 230 Vac items and 3 inputs • Pressure Sensors • Temperature Sensors • • • “Peoplefeelbetterinin.

Anatomy of a Control System Cable Network Comms and power networks must be protected. Should be installed with metal clips to maintain installation in a fire. Fire rated cabling to Category 3 of BS 8519 for Life Safety Systems. Tested under fire conditions for: - Heat Water jet Impact 3 Phase Power Cables should be classed as F 120 Comms/230 Vac/24 Vdc Cables should be PH 120 + “Peoplefeelbetterinin.

Anatomy of a Control System Testing and maintenance • Smoke control is a life safety system, covered by the RRO. Testing and maintenance is covered by BS 9999 Annex V • Regular testing – weekly • Three monthly full test • Annual inspection and maintenance by a competent person BS 9991 BS 9999 SCA Guide BS 7346 -8 Documentation “Peoplefeelbetterinin.
