Time's up! Race to replace the alarms in affected buildings!

How to tell an alarm is at end-of-life

1. Check Date Code

Remove one alarm from the mounting bracket and check date of manufacture printed on the back. If dated 2013 or earlier, the alarm needs replacement. Continue checking alarms on site as many buildings had alarms installed in all units at same time.

2. End-of-Life Signal

Alarm “chirps” 5 times with 5 Green LED flashes once per minute. These chirps will repeat even if batteries are replaced.


BRK alarms in 2013 were designed for 7-Year end-of-life. The states highlighted in blue adopted CO legislation in 2013 and will be experiencing the end of live "chirp".
