How to trigger fire emergency alarm?
There are two kinds of trigger mode on rear panel: Electric Level or Short Circuit. As diagram shown
above, in Electric Level mode, only when a short circuit occurs between two poles of the 10K resistor, it
will trigger the appropriate emergency; In Short Circuit mode, press the trigger switch, internal A and B
short-circuit is turned on, it will trigger the corresponding amplifier to send out an emergency signal. (Note:
one input can trigger several output, it can be configured in PC software).
4.3 View Working Status of Zone Amplifier
In Main Menu, press Zone Amplifier to view submenu:
1. Network Status: Online/Offline; this icon shows physical and logical connection state between host and network.
“Online” is displayed in green and “Offline” is displayed in yellow.
2. AC Power: Normal/Fault. This icon shows AC ~220V main power status: “Normal” or “Fault”.
3. Sleep: Open/Closed. This icon shows working status of zone amplifier when there is no input signal. Closed:
amplifier controller won’t turn into power saving mode when there is not input signal; Open: amplifier will turn into
power saving mode when there is not input signal.
4. DC 24V Backup Power: This icon shows backup power status: Normal/Fault/Unconfigured. It will show as
“Normal…” (in green) while host has detected that DC 24V is connected; it will show as “Fault…” (in yellow) while
battery voltage is low, battery is disconnected, operating temperature exceeds the set value or charger is faulty; it
will shown as “Unconfigured” (in grey) while there is not battery connected. (Only when system has equipped with
backup power, you can enter and view. To view working status of other zone amplifiers’ backup power, please press

•
Network Status: Online or Offline (detect communication connection of charger), it will show as Online when it’s
normal.
•

disconnected).
•
Battery: 3 kinds of statuses: Connected, Normal-voltage/Disconnected, Low-voltage/Connected, Low-voltage (system
can detect accumulator’s voltage).
•
Battery Operating Temp. Range: +80,-30 Celsius degree (Temp. unit has 2 modes: Celsius and Fahrenheit—configure
in software, default setting is Celsius).
•
Battery Operating Temp.: +00 Celsius degree (system detects accumulator operating temp.) Check other charger
status by pressing up and down icon when there is more than one charger.
