1.NOTE
This 8-channel flashing alarm device supports standard TTL signal input (0–5V, high-level trigger) and relay control output (ON/OFF).
Power Supply
Supports AC220V or DC24V power input. Please confirm the correct power supply before installation to prevent equipment damage.
Operating Conditions
Recommended operating environment:
Temperature: 0–50°C
Humidity: ≤85% RH
Keep away from strong corrosive gases and harsh environments.
Input Requirements
Passive contact input only. Do not apply any external voltage or power to the input terminals.
Alarm and Mute Function
When multiple alarms are triggered simultaneously, pressing the mute button will silence the buzzer while the corresponding alarm indicators remain active until all alarm conditions are cleared.
Optional Functions
External mute button and external test button functions are available upon request.
