A middle school is being expanded by two classrooms and about six small offices and supports spaces. The addition is separated by a fire barrier from the main school, and the existing school has a temporal-3 horn/strobe fire alarm system throughout (and is fully-sprinklered).
Current code requires an emergency voice/alarm communication system for the expansion, which the design team intends to provide.
The question is how to address the interaction between the new voice system and the existing? Is this purely and AHJ call?
Ideally, the school should consider upgrading their entire fire alarm system to voice for a cohesive message and best benefit. However, funding is very tight and we're not confident they'll have the support they need to do a full upgrade at this time.
