Boltek GSM-1 Text Message Notification Dialer

The GSM-1 connects directly to the ERL-10 Programmable Relay Module to send SMS messages automatically when local lightning is detected without the need of a computer or laptop after the ERL-10 alarms are configured. The GSM-1 supports over 500 numbers and can be controlled by a single master cell phone by sending SMS commands to add and remove numbers.

In the standard configuration, the ERL-10 receives data from the EFM-100C Electric Field Monitor, when lightning is detected, the relay module will activate a switch which then signals to the GSM-1 to send messages to the numbers programmed into the GSM-1. Once lightning is no longer detected, another message will transmit indicating an all clear status.

A valid GSM/GPRS micro SIM card with a text/data plan from a cell phone provider is required for operation.
