I. Product features:

power off alarm is also called power failure alarm and data center power off alarm. When the power grid is cut off or the power supply wires and cables are cut off, the alarm will be whistle immediately, and the alarm will not be stopped until the power supply is restored or the battery is exhausted, it is suitable for computer rooms, electrician duty rooms, power companies, etc. It can also be used for household monitoring of anti-theft alarm when wires and cables are stolen. The power indicator light of this product can make the power supply status of the power grid clear at a glance; The design of high voltage resistance can work at 260V for a long time, and it is not easy to damage even if the power grid voltage exceeds the standard in the middle of the night; The drawer-type battery cover switch is convenient, the battery can be easily replaced; The built-in trickle automatic charger can use both ordinary batteries and rechargeable batteries; When using rechargeable batteries, the standby life is up to 10 years, it can prevent underreporting accidents caused by battery failure not being found.

II. Technical performance:

1. Alarm mode: the alarm can be whistle when the power grid is cut off or the power supply wires and cables are cut off until the power supply is restored.

2. Monitoring voltage: AC175V ~ 265V. Products with AC/DC3V ~ 48V, 380V and other voltage can be customized.

3. Working voltage: DC9V(1 GF22 battery).

4. Alarm volume ≥ 115 decibels.

5. Power indicator light: it can make the power supply status of the power grid clear at a glance.

6. High voltage resistance Design: professional circuit design can work at 260V for a long time, even if the grid voltage exceeds the standard in the middle of the night, it is not easy to damage.
