Fire Alarm sounders are a critical part of any fire alarm system. Most modern systems whether it be a wired or wireless fire alarm usually will have electronic sounders. The bell sounders are usually found on the older type of system.
The minimum sounder level on a fire alarm protecting a commercial building is 65 decibels, or 60 decibels for the outer rooms. However, sleeping areas require 75 decibels at the bed head.
Wireless fire alarm sounders have now started incorporating the base sounder along with wired systems, but the cost for the wireless fire alarm sounders can be quite expensive.
