due to voltage drop (Safety threshold 9,6V), be-
cause this condition can damage the battery
Dynamic Test The Dynamic Test monitors the oper-
ating capacity of the battery. Failed Test (battery does
not meet the Test requirements) will be signalled by the:
Ø Warning power trouble event;
Ø ON status of the G indicator on Keypads.
If this occurs, the backup battery must be replaced im-
mediately, otherwise, the system will be unable to func-
tion in the event of Mains failure (black-out).
Battery trouble restoral will be signalled by the:
Ø end of the Warning power trouble event;
Ø Off status of the G indicator on Keypads.

The Main Unit Tamper Microswitch is enabled by the
initial closure of the Control panel. Therefore, it cannot
trigger a Tamper on Panel event on first power up.
Likewise, if the Panel is opened during a programming
session (via Keypad or computer), the Tamper
microswitch will be inhibited thus unable to trigger a
Tamper on Panel event until the Programming ses-
sion ends, and the Panel is closed again.
n Note about Switching Power Supply
KYO320 control panel supports BAW50T12 Switching
Power Supply (factory default).
If it is necessary more Power Supply/Battery charger
the BAW75T12 is avaible (accessory item). In this
case it is necessary to remove the BAW50T12 from the
backplate of control panel and so work carefully through
the following steps.
1. Disconnect the BAW50T12 from Main Board;
2. remove the screw (57a) and pull the BAW50T12
from the hook on the backplate of control panel;
3. Before installing cut the two BAW75T12 wires for
connecting battery;
4. Insert the BAW75T12 in the same location of
BAW50T12 (Figure 1): before in the hook and then
secure the screw (57a).
5. Connect the connector (53) on Main Board and if
scheduled the termal probe (KST), connector (62);
Otherwise KYO320 control panel can manage
BXM12/30-B and BXM12/50-B Power Stations
(see page 7).
