It is recommended to use timing power socket 1 to supply power for the system partition amplifier, but when
the power consumption of the amplifier exceeds 400VA, a power time sequencer is needed, that is to say, the
timing power socket 1 drives the power time sequencer, and the sequencer drives the amplifier. Timing power
sockets 2, 3 and 4 can externally connect sound source devices for power supply.
3—3 Running of typical system
3—3.1 After confirming that the line is connected well, start the power of the device with a special switch key,
the power indicator light will begin to flash yellow; and the starting time will be about 40s. After it is
started, the power indicator light will stop flashing, and turn green; a language selection interface will
appear on the screen, then you can click the language selection button on the touch screen (optional),
and you will enter the main interface. And also, you can operate it via the touch pad at the right side of
the screen. Move on the touch pad with your finger, and the cursor on the screen will move accordingly.
After the cursor moves to the button that you need, you can just click the touch pad to complete the
selection. Or you can connect a mouse to the USB interface to operate it. The special version for
Chinese Mainland has no language selection interface. After it is started up, it will directly enter the
Chinese main interface.
3—3.2 Generally, the “program control” button below the main interface will shine (otherwise you can click it
to let it shine), and the system will run under the program control (programming method is detailed in
section 4). Under this condition, the background music provided by the DSPPA special sound source and
inner CD will play on time according to the programs preprogrammed by the user; chime will played
punctually and automatically at program control timing points, and the corresponding power channel will
be opened or closed automatically on time. And also, the system will correspond to the telephone, remote
call, alarm partition breaking in.
3—3.3 Alarm signals from the fire control center will start the first class prior partition breaking in itself, and the
scope of alarm breaking in is determined by the program. Within the alarm break-in area, all other
programs are overridden by alarm whistles or voice files (e.g. evacuation command) determined by the
program, until the alarm is cleared. However, the emergency microphone on the front panel can override
the alarm whistles for easily giving on-the-spot commands.
Alarm signals from the fire control center will also start the telephone module to dial an alarm call
(special function).

Signals from the remote call terminal will start the second class prior partition breaking in, and the
break-in area is determined by the remote call terminal. Only when an alarm is given in the called area,
the call in this area will be prohibited. There can be 48 remote call terminals, of which the priority will be
determined by the manufacturer. When a call area is occupied by a call terminal, the partition indicator
lights of other call terminals will flash, and terminals with a low priority will have no right to occupy,
while terminals with a high priority can take over it. Call volume can be adjusted by adjusting the
MIC
VOLUME
at the back of the terminal (see details in MAG2588 specification), or by entering the "
call
setting
" interface in the "
system setting
" (see 4-10).

Telephone can start the third class prior partition breaking in (second to alarms, partition calls), and the
break-in area (phone receiving area) and speaking area will be determined by the preprogrammed
program. When the telephone module receives a phone call, it will automatically “lift off the hook”, and
