ACOUSTICS INHIBITION

This menu allows to disconnect momentarily the acoustics corresponding to the different events that can be displayed. If the
event that went off the acoustic reappears or a different one appears, then the acoustic will be automatically activated.
The events with a corresponding acoustic are the following:
• Ventilation Level Acoustic –one per group- (1st and 2nd speed).*
• Alarm Level Acoustic –one per group-.
In the highest reading mode, the detector causing it will be displayed.*
• Saturation Acoustic: Equipment Bottom of scale for the different gases.*
• General Group Fault Acoustic: Group/s nº are displayed.
• Detector Error Acoustic: Detector/s nº are displayed.
• Sensor Error Acoustic: Detector/s nº are displayed.
• Power Fault Acoustic.
• Battery Fault Acoustic.
• WARNING, PRE-ALARM and ALARM acoustic with explosive gases.
* Just if the activated acoustics for these modes have been programmed.
1. Press ACOUSTIC INHIBITION to disconnect the acoustic signal while the event is displayed.

5. OPERATION MODE WITH EXPLOSIVE GASES -EXP-

The function of the VENTILATION (AUTO/MAN/STOP) push button will be limited to activate the different electrovalves of gas
cut in each group (Gr1 – Gr2) manually. It will be necessary the system to be in Pre-alarm mode.
1. Press VENTILATION.
"Auto" is displayed.
2. Press VENTILATION again.
"Manu" is displayed.
3. Press ENTER to memorise.

ALARM LEVELS

EUROSONDELCO includes 3 programmable alarm levels.
WARNING: An acoustic signal goes off when the 10% L.E.L. is reached -default level programmed-.
PRE-ALARM: An acoustic signal goes off and Relay 1 in Group 1 is activated when the 20% L.E.L. is reached -default
level programmed-.
ALARM: An acoustic signal goes off and Relay 2 in Group 1 is activated when the 40% L.E.L. is reached -default
level programmed-.
Relays 3 and 4 will have the same functioning than the previously described for groups 1 and 2.
