H3S Power Alert

 

The power alert system from H3S is a remote GSM mains monitor designed to transmit text messages to stored phone numbers when a mains failure is detected. The unit can store up to three numbers, which are set by sending commands via text message to the phone number associated with the inserted SIM card. When a mains failure is detected the unit will send up to four messages, once an hour, warning of a mains failure to each one of the stored numbers. After this time the unit will enter status mode and will not come back online until power is restored. The unit also has an auxiliary input to which and external switch may be connected.

 

 

Before the unit can be used a valid, full sized SIM card needs to be inserted. The SIM card will need to be already registered with the SIM card provider and have credit on it if it is pay as you go. The SIM will also need to be unlocked and not PIN protected, which most SIM cards are by default. It is recommended that the SIM card be first tested in a regular mobile handset to ensure that it is working properly, as not all providers can guarantee reliable operation. It may also be worth disabling voice message notifications.
