EST3 Rules-Latch,Set,Low,Med,High,ENABLE (how it works)

Rules- Latch,Set,Low,Med,High,Enable,disable (how it works)

The EST3 can use Priorities to turn outputs on and off.

e.g.
OFF -LOW SUP '*_Alarm_*'
OFF -MED SUP '*_Alarm_*'
OFF -HIGH SUP '*_Alarm_*'
OFF -SET SUP '*_Alarm_*'
OFF -LATCH SUP '*_Alarm_*'

OFF SUP '*_Alarm_*' SAME AS OFF -MED SUP '*_Alarm_*'

Priorities also use counters, Which Means if an output is turned on or off more then once it will count the number of times
e.g.
on -LOW '1Alarm'
on -LOW '1Alarm'
on -LOW '1Alarm'
On -MED '1Alarm'
On -MED '1Alarm'
OFF -HIGH '1Alarm'


Output 1Alarm has a count of
(On low 3 times, On medium 2 time, Off high)
Which means the output is off.


SET: how it works
The SET takes control of the output without reseting the counters. The counters will count up and down while the SET has control.
Once the SET is back to its Normal state, the priorities and counter take control back.

SET is what the ALARM SILENCE button uses. If the Alarm Silence is pressed all AV's are set to OFF and held there.
If pressed again the priorities and counter take control back and the AV's turn on. If the system is reset and the
devices which was in alarm resets, the Alarm Silence LED goes just as if you press the ALARM SILENCE button.

[ALARM SILENCE]
ALARMSILENCE:
OFF -set AUDIBLE '*',
OFF -set visble '*';



LATCH: how it works
The LATCH sets the output on or off and resets all priorities and counters to ZERO.
e.g. OFF -LATCH '1Alarm'
The output is now in the Quiescent state (at rest or inactive state)
Note: if you LATCH off an output that is in Alarm when the device is resets all its outputs will be OFF with a count of ONE.
Be careful with the LATCH.

DISABLE/ENABLE: how it works
When a output is DISABLE it works the same as the SET with respect to counters and priorities
OUTPUT IS:
Disable - ( off )
On -High - ( off )
Enabled - ( ON )

Also if you select {Restore Event on Disable} under the project->operations tab, This can be very useful when a device goes into ALARM, you can disable the INPUT and all the OUTPUTS will be Restored.

IRC3 - The irc3 system used the term "Latch with a 99'' and "Set priority 00" which work the opposite of the EST3 system, so do not get confused.

By using the EST3 display you can turn outputs on/off (latch,set,high,etc) to test what will happen, I used a switch panels's LED as the output
