The FIRETEXT SMOKE ALARM:
1. Independent of mains power supply
2. Internal GSM module therefore not reliant on additional hardware
The FIRETEXT alarm is not reliant what-so-ever on mains power supply and is therefore truly a stand alone safety device.
The FIRETEXT 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.
