It’s a very simple but clever idea. This fire/smoke alarm has a quad-band GSM chip to allow it to send SMS alerts to your phone whenever it detects smoke. Great for the Smart Home.
Considering how glued we are to our mobile phones, this is a useful feature. I would like to know if there was a fire in my house, even if I’m not there to hear the ear-splitting scream of the smoke detector.
According to the manufacturer:
Each Text Messaging Smoke Alarm has a 9V Lithium battery that will provide a minimum of 36 continuous activations. Zero activations can result in a life span in excess of 5 years. Average usage should result in a battery life of 2-4 years. If tested weekly the battery will need to be replaced every 3-6 months.
Each unit comes with a bespoke pay-as-you go SIM.
