product that automatic monitoring and signal alarm for power and industrial.

2，FUNCTIONAL CHARACTERISTICS
1）The panel includes digital display and power on self test (POST).Integrated design.
2）Provide with test (light test), confirm (accept), return（reset）, signal recall and clear function. With
function buttons.
3）Provide with manual and automatic accept function, automatic accept time limit (0-200s) able to set.
4 ） Signal alarm type able to distinguish: accident signal S, warning signal Y, position signal P, all
available to set.
5）Alarm window color: able to choose red, white, yellow, green, accord to signal alarm type, separated
by color is more arresting and visually.
6）Input signal status: switch contact (h), switch hold contact (E), and pulse hold contact (C). (Note)
7 ） The input signal is normally open and normally closed. For each signal, the normally open and
normally closed alarm (default) can be set, and the normally closed variable normally open alarm can be
set.
8）Signal delayed alarm: 0-9999ms delay alarm time limit able to set.
9）Device bring with buzzer, when accident happy it sounds “bi---”, warning signal sounds short beep “bi,
bi, bi, bi”, position signal doesn’t sound.
10）Device with accident and warning signal alarm output contact, able to activate electric bell, enhance
the alarm effect.
11）With remote signal output contacts, connect to other devices or as an accident stop signal.
12）It has the device power disappearance contact output.
13 ） Provide with digital communication output, RS485 serial communication contact, MODBUS
communication protocol.

◆Note: Explanation of input signal status and alarm procedures

When“h” is selected as the input signal state (default), the workflow is as follows:
Line Run Button Alarm status Light plate Sound status Remark
1 Normal - Normal Off Silent
2A Abnormal - Alarm Flash Sound Alarm
2B Abnormal Silence Alarm Flash Silent Alarm hold
3A Abnormal Confirm Comfirmed Bright Silent Alarm hold
3B Normal - To line 4 Instant alarm
4 Normal - Normal Off Silent Automatic reset
When the state of the input signal is "C" or "E", the work flow is as follows:
Line Run Button Alarm status Light plate Sound status Remark
1 Normal - Normal Off Silent
2A Abnormal - Alarm Flash Sound Alarm
2B Abnormal Silence Alarm Flash Silent Alarm hold
3 Abnormal/Normal Confirm Comfirmed Bright Silent Alarm hold
4A Abnormal Reset - To line 3 Alarm hold
4B Normal Normal 灭 无声 Manual reset
Note: The signal is normal if the signal is not alarmed, and the signal abnormal is if it is alarmed

4，DEVICE ALARM AND TESTING

1）POST (power on self test), when device power on, digital display window on device panel
shows in sequence 【0.0.0.0.0】【1.1.1.1.1】…【7.7.7.7.7】【8.8.8.8.8】alarm window all
light 【9.9.9.9.9】alarm window all light scroll display 【CA n L】(for power indicate). POST
finish. "n" is the total number of circuits of the alarm device.
2） Press “test” button, all alarm window flash, buzzer sounds, output audio equipment
act. Release test button, return to monitoring status.
3）When signal alarm, recording alarm window flash, and buzzer sounds, output audio
equipment act to start electric whistle sound. Digital display window shows recording loop
number.
4）Press “confirm” button (or 0-200s affirm automatically), alarm window turns from flash to
light, buzzer silence, output audio contact return, electrical whiles and bell silence.
5）When signal return, switch type contact input signal recording alarm window lights off.
Retention type contact input signal alarm window remain alarm, require manual reset (press
“reset” button), and alarm window lights off.
6）Long press “recall” button, alarmed signals will shine one by one which followed alarm
sequence by FILO (first in last out) rules. At the same time LED display shows alarmed loop,
maximum 200 signals can be recalled, and alarm signals have priority.
