14 System Events Option
•
System Events provide a flexible way of performing more complex cause-and-effect programming than that
available from the standard zonal ringing. Most systems do not require system events.
•
Individual detectors can be made to generate system events.
Entry via a PC is strongly recommended if many detectors are to generate events. (Refer to
the PC Programming Manual for further information). If there are only a small number to
enter, then this can be done directly from the “Device” change option on any of the loops.
•
Event numbers can be any number from 1 to 200. Event number 0 is used to denote an “unused” event input or
output.
•
The events can be shared over a network of panels if required by setting the Network, System Events to be
“[Global]”.
•
For example, say the operation of a call-point on panel 1 on loop 2, address 3 in one building is required to
energize an extract fan connected to relay 2 on panel 6. The steps to achieve this would be
1. At panel 1, add an arbitrary system event number ( Say 20 ) to the call-point.
2. At panel 6, allocate the extract fan output to system event 20.
3. Check that both panels have the Network option set for System events to be global.
•
Most system events are latched and held until the panel is reset. Transient system events will automatically be
removed once the device that caused the event is restored to its normal condition.
•
Input devices with action set to "Non-latched" create transient events. A transient event is held local to the panel
of origin - it is not transmitted over the network.
14.1 Event Modes

Press
4
to select the ‘Events’ option from Page 3 of the commission menus. The display shows the event options
available:
System Events : 1)General 2)Logic
3)Define outputs
•
All System Events apart from the “General” events are normally programmed on a PC.
