Operation Control-By-Event Operation112 AFP-200 PN 15511:H2 10/14/20024.3.8 How the Control Panel Indicates a Panel Circuit Trouble• The SYSTEM TROUBLE LED flashes• Trouble relay turns on• A message is sent to the LCD display, History buffer, and installed printers,terminal mode LCD-80s, and CRT-2s• A TROUBL status banner and a B ELL C IRCUIT Type Code is displayed on the LCDdisplay, along with information specific to the device, as shown in Figure 107.Figure 107 Sample Display of a Panel Circuit in Trouble4.4 Control-By-Event OperationControl-by-event (CBE) is done through 99 software zones. Each system point(detector, control module, monitor module, relay module, or NAC) may list up to fivezones in its program information. A general alarm zone (Z00) may be listed for output(control) points, but is not necessary to list for input points. Z00 is not activated bynon-alarm or supervisory points.If any input device (detector or monitor module) becomes active and it is not disabled,it activates all software zones in its list. An output device (control or relay module, orNAC) that is not disabled is turned on if any of the software zones in its list are active.This is basically an “or” functionality. Zones 90 through 99 are reserved for specialfunctions such as releasing (Refer to Section 3 “Programming”).Control-by-event (CBE) control is done through 99 software zones. Each input point(detector, monitor module) and output point (control or relay module, NAC/PanelCircuit) can be programmed to list up to five software zones. Non-Alarm orSupervisory points do not activate software zone Z00 (general alarm).Zones 90-99 are reserved for special functions such as releasing (refer to Section 3“Programming”).Input and output devices with listed software zones work as follows:• Inputs – When an input device (detector or monitor module) activates, so do allsoftware zones listed to the input device.• Outputs – When a software zone activates, the output device (control or relaymodule, NAC/Panel Circuit) turns on.Figure 108 shows an illustration of simple CBE for Zone 04.Figure 108 CBE ExampleTROUBL BELL CIRCUITPANEL CIRCUIT NO. 1Z00 SHORT CIRCUIT10:21A 07/24/98@ B01Status banner TROUBLType Code BELL CIRCUITAddress of the NAC(B01-B04)Type of trouble (shortcircuit shown)Input – Detector atSLC address 12listing Z04 in itsCBE.D12Z04B04Z04Z04Output –NAC/Panel CircuitB04 listing softwarezone Z04 in its CBE.Software Zone – Zone 04Technical Manuals Online! - http://www.tech-man.com
