3.2.3 Advanced mode question
The system ask about advanced mode yes or not option. In advanced mode user will
be able to select A+B speaker lines configuration. Once selection is done system will
follow these steps to self-configure.
a) Zones and speaker lines. Zones
The system checks automatically the loudspeaker lines, looking for the ones that are
being used. They must be connected in order since when the equipment detects a line
with impedance higher than the measurement range (600 Ohm), it considers that neither
this line nor the following ones will be used.
When the user wants to use a line with high impedance (more than 600 Ohm), install
an end of line terminal (LDATFL2) in order to let the equipment recognize it as a zone in
use. All the detected zones are configured with active line supervision, but this can be
changed from the menu
Configuration/Zones
.
Using the active line supervision volume controllers cannot be used, because the input
impedance varies depending on the adjusted level.
b) CIE Interface (Fire Detection Central)
The system checks that the inputs are connected correctly with the specified
terminators (2.2.3). When it detects the end of line (EOL) devices the supervision of the
general input and/or the connected zone inputs will get activated. If the EOL devices are
not detected they will remain active without supervision, working in dry contact mode.
c) Battery
Battery management depends on the installation of the charger accessory EN54-4.
The system checks if the microSD card is installed with the charger module. In this case,
the system will check that there is an installed battery, checking the voltage and the
internal impedance. Minimum working voltage is 10,5 V with a maximum impedance of
200mOhms
. We recommend to adjust impedance according to installed battery once
this is 100% charged.
d) ACSI devices
Connected ACSI devices always are automatically detected after some seconds.
Using the automatic configuration they remain installed in the system so that a failure will
appear later if any Voice Alarm Panel (VAP) or microphone (MPS) get disconnected.
It should also be tested that the devices addresses are correctly configured and that
the end of line device of the last bus device is active.
e) Backup amplifier
The backup amplifier is activated automatically and amplifier supervision too. It will
show failure if in any moment any of them stops working or does not offer the gain level
calibrated.
f) Setup Report
Once auto setup is finished screen will show the number of zones and lines installed
and ACSI devices detected. Check this info and configure manually if necessary.
