1. AutoStandby mode
The purpose of the operation in Standby mode is:
» limiting the power consumption from the battery while the primary AC 230 V power is lost;
» reduction of heat generated by the amplifier modules while working on the primary power source at any preset time,
if the system does not have any active matrices it goes into standby / idle mode.
Principle of Standby operation
Standby mode is activated automatically and every time when the following conditions are met simultaneously:
» there has been a loss of primary power supply (230 V) and the system switched to battery power
or
» system has no active audio matrices and operates in Normal mode (no Alarm).
While working in active Standby mode the AutroVoice miniVES system periodically changes its operating states to the
following sample states:
» active_state
» suspended_state
Duty cycle of the above conditions is as follows:
» suspended_state – 85 seconds
» active_state – 5 seconds
Central processing unit actions in Standby mode:
» Periodically sends signals to the amplifiers indicating the current mode and operating state to enter
amplifiers into power saving mode.
» Periodically sends signals to all the control cards (xCtrl-2, xCtrl-4) informing cards about the current state of work
( active_state / suspended_state ) to force a power saving state to control cards (or exit from this state).
» Each time while sending a command to change the state of the control card – it verifies whether the card has changed its
state and if it properly reacts to read state.
» Switching control and error reporting is done automatically after sending commands to change the status on active_state
and confirmation from the card it has exited this mode.
Amplifier module actions in Standby mode:
» During operation in the suspended_state amplifier modules enter a reduced power mode (amplifiers stop working and do
not consume energy or consume a minimum value of it).
» During operation in the active_state amplifier modules that entered a reduced power mode return to normal operation.
Standby mode is called using the Standby function.
» That function can be activated by using:
Ű timers (it can be called in a cyclic manner at any preset time);
Ű any logic inputs;
Ű programmable “Key” push buttons;
Ű automatic run in the absence of active matrices defined by the user time [min]
AutoStandby .
» This function can be activated under the following conditions:
Ű system is not in alarm mode;
Ű there are no active audio matrices with
Emergency / Service priority;
Ű system is powered from the primary source 230 VAC (while switching to emergency battery power it happens
automatically if the system is not in alarm mode and there are no active Emergency / Service matrices).
AutoStandby – the function is activated / deactivated by the user on the level of the configuring software in the form of a check-
box. The function is activated in the absence of active audio matrices of Emergency / Service priorities after the time defined in
the Configurator has passed.
