1. Product Overview
The Sonew Automatic Power Cut Failure Alerter is designed to provide immediate notification in the event of a power outage or failure. It features an LED indicator to show the power status and emits a loud 120dB siren when the power supply is interrupted. This device is ideal for monitoring critical appliances like freezers, or for security in industrial and mining enterprises, substations, telecommunications rooms, and farms.

3. Setup and Installation
3.1 Battery Installation
The device requires one 9V battery for operation during a power outage. The battery compartment is designed as a drawer-type cover for easy access.

Figure 3.1: Battery Installation
Locate the drawer-type battery cover on the bottom of the unit. Slide it open and insert a 9V battery, ensuring correct polarity. The diagram shows the positive and negative electrodes for proper insertion. The device will not function without a battery.- Locate the battery compartment cover on the bottom of the unit.
- Slide the cover open.
- Insert a 9V battery, paying close attention to the positive (+) and negative (-) terminals as indicated inside the compartment. Incorrect polarity will prevent the device from working.
- Slide the battery cover back into place until it clicks securely.
3.2 Connecting to Power
Once the battery is installed, connect the alarm to a standard AC power outlet. The device is designed for high voltage resistance.

4. Operating Instructions
The Sonew Power Cut Failure Alerter operates automatically once properly set up.

Figure 4.1: LED Indicator
The red LED on the front of the device indicates the power status. When illuminated, power is present. When it goes out and the alarm sounds, it signifies a power failure.
- Normal Operation: When the device is plugged into an active power outlet and the switch is "ON", the LED indicator will be lit, signifying that power is present and the device is monitoring.
- Power Outage Alarm: If the AC power supply is cut off (e.g., due to a power outage, circuit breaker trip, or unplugging), the device will immediately activate its 120dB siren. The LED indicator will turn off.
- Muting the Alarm: The siren will continue to sound until power is restored or the device is manually muted. To mute the alarm, slide the on/off switch to the "OFF" position.
- Power Restoration: Once power is restored, the LED indicator will light up again. If the alarm was muted, you will need to switch it back to the "ON" position to resume monitoring.
