First Claim
Patent Images
1. A life safety device, comprising:
- a battery monitoring module configured to measure a voltage level of a battery;
an alarm module configured to provide an alarm when the voltage level is less than or equal to a low battery threshold; and
a silence module configured to automatically select a random time period and to silence the alarm for the random time period.

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; automatically selecting a random time period; and silencing the audible low battery warning for the 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; automatically selecting a random time period; and entering the low battery silence mode by silencing the audible low battery warning for the 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)
