  1. Linkage Connecting system components

  2. Basic concepts • Allows configuring automatic actions • Triggering outputs based on specific inputs • Used for removing human reliance • Also used as backup to normal operations

  3. Linkage Types Local Linkage (Self Contained) Internal Variable Linkage (Controller Based) Reaction Linkage (Global – System Wide)

  4. Local linkage • Reader Alarms to Auxiliary Relays • Alarm Panel Inputs to Output relays • Only Control Outputs from same device • Limited Configuration Options • Only power to Device Required • Very Useful for Redundant Backup • Extremely Fast Reacting • Removes Reliance on Human Operators

  5. Local Linkage - Example Sensor Device changes input state to ‘Alarm’ Alarm Input Linkage action is internal to the device, no outside action Output changes state in reaction to alarm input

  6. Local Linkage Programming

  7. Internal variables - general • Configured in Software, stored in Controller • Can affect any device on controller • Inputs from one device can control another • PC’s or network not needed • Very fast acting • Removes requirement for extra wiring • Also useful for redundant backups • Removes Reliance on Human Operators

  8. Internal variables - what • Alarm Panel Relays • Reader Auxiliary Relays • Masking Individual Alarms • Masking Alarm Groups • Unlocking Doors • Time Zone Activation • Testing Active Alarms Before Masking • Can be Long List of Many Functions

  9. Internal variables - when • Alarm Panel Inputs • Reader Alarms • Reader Auxiliary Inputs • Access Grant • Access Deny • Duress • Can Count Access Grants • APB Area Counts

  10. Internal Variable- Example Devices change mode to OPEN on designated readers Alarm Input Change is detected in controller, signal is sent to devices to change state Sensor Device changes input state to ‘Alarm’

  11. Internal Variable - Configuration

  12. Reactions - general • Configured in Software, stored in PC’s • Can affect any device on System • Inputs from one device can control any other • PC’s must be Functioning • Requires APACS PRO software • Uses Network to send info to other PC’s • Removes Reliance on Human Operators

  13. Reactions - what • Alarm Panel and Reader Relays • Wave File Sounds • Live Video and Video Verification • CCTV Control (Camera Selection, etc.) • Changing Reader Modes • Paging Systems • External Program (Word, Email, etc.) • Time Delays (Pause) • Can Be Long List of Many Functions

  14. Reactions - when • Menu Selection and Hot Keys • Graphic Map Buttons • Event Message Masks • Access Grants from Specific Cards • Any Type of Alarm Input • Trigger only During Certain Times • Configure Menus for Operator Selection

  15. Reaction - Example Alarm Mode Station receives message and reaction is executed Alarm Input Sensor Device changes input state to ‘Alarm’ -Email is sent -Popup message displayed to guard Sensor Device changes input state to ‘Alarm’ Controller detects change, sends message to Alarm Mode station

  16. Reaction - Configuration

  17. What about…? • What is the best solution for the following? • Open all doors in response to an input from PAGA (Public Address & General Alarm) system? • Turn on lighting? • Notify the security director when perimeter alarms are detected after midnight? • Sound an alarm when a gas alarm is pulled?
