siren offline

Hi @mckstl01,

Most likely, the batteries in your Siren need to be replaced. To replace those, follow these steps:

1. 
   
2. Slide the Siren up and off of its mounting bracket.
   
3. Using a Phillips-head screwdriver, remove the four screws that are holding the battery cover in place.
   
4. Remove the battery cover. This will expose four AA batteries, which can then be replaced.
