1. Product features:
The power failure alarm is also called the power failure alarm and the computer room power failure alarm. When the power grid is cut off or the power supply wire or cable is cut, it will immediately sound the horn to alarm. It will not stop the alarm until the power supply is restored or the battery is exhausted. Applicable In computer rooms, electrician duty rooms, power companies, etc., it can also be used for burglar alarms when households monitor the theft of wires and cables. The power indicator of this product can make the power supply status of the grid clear at a glance; the high-voltage 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 be damaged; the drawer-type battery cover is convenient to switch, and the battery can be easily replaced; The current automatic charger can use both ordinary batteries and rechargeable batteries; when using rechargeable batteries, the standby life is as long as 10 years, which can prevent false alarms caused by undetected battery failure.
