2.4 Evacuate
Pressing the evacuate button will operate the sounders if they are not already sounding. This will
override an intermittent sounding alarm. ‘Evacuate’ will be displayed on the display along with the
panel number where the button was pressed. The text location for this panel and the date and time
is displayed. A buzzer on the control panel sounds continuously. By default AUX relay 1 operates
and the hard-wired sounder circuits energise.
2.5 Alert
The alert function is designed as a warning. Pressing this button will cause the sounders to sound
an intermittent tone. It will not override an evacuate or alarm tone, but will be displayed on the
screen in a similar way to the Evacuate message. The buzzer sounds continuously whilst in this
state. By default AUX relay 1 does not operate and the hard-wired sounder circuits pulse once per
second.
2.6 Silence
If the system is in an alarm or alert state, from either a smoke detector, break glass or panel,
pressing this button will silence the sounders. A message will appear on the screen indicating the
operation is taking place. It can take several seconds for the complete system to silence. The
internal buzzer will now sound intermittently. A subsequent alarm condition from a different unit or
pressing either Evacuate or Alert will cause the sounders to re-sound.
If a fault is being displayed operation of this button will silence the internal buzzer. Any subsequent
faults will re sound the buzzer.
In both of the above situations the silence LED above the button will be illuminated. The events remain
on the screen. On the EDA-M200 the LED’s are not fitted and the status is indicated on the top line of
the LCD.
In alarm the silence operation by default clears the sounder relays and AUX 4; the AUX mask may be
reconfigured using the PC software.
2.7 Reset
Once the system has been silenced, whether it be a fault or alarm condition, Reset will cause the
system to return to normal. The reset button is disabled for six seconds after the silence has been
pressed. The display will be cleared and a message will appear indicating the system is resetting. If
the alarms or faults persist they will be redisplayed and actioned upon accordingly. If there were faults
prior to an alarm condition reset will cause the faults to be re-displayed.
In alarm the reset operation clears AUX 1 and 3 by default. In fault the reset operation clears AUX 2
by default, but will clear the relays programmed to operate on fault using the PC. These options may
be reconfigured by the system engineer.
Pressing Reset for 3 seconds in a system normal state will cause the lamps test function to operate.
This will in turn flash all LED’s and flash the LCD. This should be done as part of the routine weekly
system test.
2.8 Print
Momentarily pressing the print button will print earlier events in reverse order as previously displayed
on the screen, starting with the most recent event first. When the required events have printed, a short
press of the print button will cause the printing to cease. The print operation will terminate
automatically once the entire log has been printed. A message appears on the LCD whilst the printer
is finishing. This will take a few seconds as printing is terminated and the paper is fed out. To feed the
paper through the printer press and hold the print button for the required amount of paper feed and
then release the button. The printer is only available on the EDA-M150. If a printer is not fitted a
suitable message will be displayed.
