Battery powered SMS Smoke Alarm. Upon activation the alarm generates a user-defined text message which can be sent to a maximum of 4 mobile recipients.
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.
