easy installation and use, and small maintenance. This product is widely used in industries such as power,

2. Functional Characteristics

1. User Interface: The device panel is equipped with a digital display, setting buttons, and a power-on self-test function.
2. Built-in Buttons: Features built-in function buttons for testing (lamp test), confirming (accepting), silencing, resetting, and recalling.
3. Duty Switching: Equipped with manned/unattended switching functions.
4. Confirmation Modes: Supports both manual and automatic confirmation. The automatic confirmation time can be set from 0 to 200 seconds.
5. Alarm Type Distinction: Can be configured to distinguish between Accident signal (S), Warning signal (Y), and Position signal (P).
6. Light Signboard Colors: Available in Red/White, White/White, Yellow/White, and Green/White. Color differentiation makes the alarm type more eye-catching and intuitive.
7. Input Signal Types: Can be set to Switch type contact (H), Switch type holding contact (E), and Pulse type holding contact (C). (See Note below)
8. Normally Open/Closed Selection: For each signal, it can be set to Normally Open to Normally Closed alarm (default), or Normally Closed to Normally Open alarm.
9. Signal Delay: The delay alarm time can be set from 0 to 9999 ms.
10. Built-in Buzzer: Emits a continuous long beep for accident signals and intermittent short beeps for warning signals. Position signals do not trigger the buzzer.
11. External Sound Alarm Output: Equipped with accident and warning signal alarm output contacts to activate electric horns and bells, enhancing the sound alarm effect.
12. Remote Signal Output: Features accident and warning remote signal output contacts, which can be connected to other devices or used as accident stop signals.
13. Power Loss Output: Equipped with a device power disappearance contact output.
14. Digital Communication: Features an RS485 serial communication interface supporting the MODBUS communication protocol.

Note: Input Signal Contact Types

• Switch Type Contact (H): Momentary closing contact. When a system failure occurs, the contact closes and triggers the alarm. After the fault is resolved, the contact opens and the alarm automatically resets.
• Switch Type Holding Contact (E): Momentary closing contact. When a system failure occurs, the contact closes and triggers the alarm. After the fault is resolved, the contact opens, but the alarm signal remains active. Manual reset is required.
• Pulse Type Contact (C): Pulse momentary closing contact. When a system fault occurs, the contact closes for 1 second and then opens. The alarm signal remains active. After the fault is resolved, manual reset is required.
