The Mobeye PowerGuard CM4100 is a compact and easy-to-understand 4G LTE-M/2G alarm notification device for monitoring external power sources. The voltage is monitored by simply inserting the adapter into the socket. In the event of a power failure, the contacts will be informed via push notification/call/SMS/email. The PowerGuard is equipped with batteries that take over the functions in the event of a power failure. In the event of a power failure, the detector operates in "low power mode" to conserve battery power. Alarm messages and test messages are still sent. The device has two additional inputs (NO/NC). Devices, external sensors or contacts connected to these inputs will also be monitored. Various settings, such as alarm delays in case of power failure, user-defined alarm texts etc. are easy to program. https://elecena.pl/product/19068774/10387-gsm-power-failure-detector 2021-07-14 https://elecena.pl/product/19068774/10387-gsm-power-failure-detector 2022-07-01 https://elecena.pl/product/19068774/10387-gsm-power-failure-detector 2022-07-26 https://elecena.pl/product/19068774/10387-gsm-power-failure-detector 2022-10-08 https://elecena.pl/product/19068774/10387-gsm-power-failure-detector 2022-12-13
