14 System Events Option
•
System Events provide a flexible way of performing more complex cause-and-effect programming
than that available from the standard zoned 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.
•
System Event numbers can be any number from 1 to 200. Event number 0 is used to denote an
'unused' event input or output.
•
These 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 as follows:
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.
An unlatched (transient) event used with a second event through a logic sequence to create a
third event will be latching.

All System Events apart from the 'General' events are normally programmed on a PC.
