4.4 Control-By-Event Operation

Control-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 five zones 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 by non-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, or

NAC) 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 special functions 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/Panel

Circuit) can be programmed to list up to five software zones. Non-Alarm or

Supervisory 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 all software zones listed to the input device.

• Outputs – When a software zone activates, the output device ( control or relay module

, NAC/Panel Circuit) turns on.

Figure 108 shows an illustration of simple CBE for Zone 04.
