7. A method of monitoring a voltage level of a battery in a life safety device, the method comprising:
-
periodically measuring the voltage level of the battery;
providing an audible low battery warning when the voltage level of the battery generally equals or is less than a low battery threshold; and
silencing the audible low battery warning for a random time period when the voltage level of the battery is determined to be generally equal to or less than the low battery threshold. - View Dependent Claims (8, 9, 10, 11, 12)

13. A method of monitoring a voltage level of a battery in a life safety device, the method comprising:
-
periodically measuring the voltage level of the battery;
entering a low battery mode when the voltage level of the battery generally equals or is less than a low battery threshold, wherein the low battery mode includes providing an audible low battery warning; and
entering a low battery silence mode by silencing the audible low battery warning for a random time period when the voltage level of the battery is determined to generally equal to or less than the low battery threshold. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20)
