2. System Overview
Nowadays the building is higher and higher and the area need to be controlled at the same time is becoming
wider and wider. If EVAC System also is designed based on the traditional analog technology, there are problems
about signal attenuation from the long-distance, electromagnetic interference between dierent space, the cost
of construction and maintain, the system centralized control and monitor, the data backup, the more redundancy
and so on.
EVAC System is designed for solving all the above problems. It is a perfect PA system solution that meets the
demands of re alarm, public address and BGM. It is controlled by eective MPU Module without linkage problem

equipped with four main ampliers, it will show: 01 02 03 04)
• Main Amplier: Normal/Fault/Sleep. It shows working status of main amplier: it shows as Normal when main
amplier works well; it shows Fault when amplier output AMP loop is short-circuited or faulty. If sleep function is on
and more than 3 minutes without input signal, it will switch to sleep-mode to save power (congure in software).
• Spare Amplier: Normal/Fault/Sleep. It shows working status of spare amplier: it shows as Normal when spare
amplier works well; it shows Fault when amplier output AMP loop is short-circuited or faulty. If sleep function is on
and more than 3 minutes without input signal, it will switch to sleep-mode to save power (congure in software).
• Physical Zone: Normal/Open/Short/Ground. It shows channels working status of current main amplier: it shows
as Normal when connection is good; it shows as Open when loop between H and C is open-circuit; is shows as Short
when loop between H and C is short-circuit; it shows as Ground when H and C of output terminal is grounded.
• Switch Instruction: How does amplier changeover switch main amplier to spare amplier automatically? For exam-
ple: If rst channel main amplier breaks down, rst spare amplier will be switched to main channel 01 output; if third
channel main amplier breaks down, rst spare amplier will be switched to main channel 03 output; if several main am-
pliers break down at the same time, system will switch in following order: CH1>CH2>CH3>CH4>CH5>CH6>CH7>CH8.

How to trigger the re alarm?
How to trigger re 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 amplier to send out an emergency signal. (Note:
one input can trigger several output, it can be congured in PC software).
