Will manually turning off a shunt trip breaker set off the fire alarm?

Manually turning off a shunt trip breaker should not set off the fire alarm. The only way that the breaker could set off the fire alarm when turned to the off position is if there is an auxiliary contact on the breaker connected to the fire alarm circuit. This is not usually done because the breaker should be able to be turned off when doing maintenance on the breakers circuit. If the breaker is a mandatory feed breaker to a piece of fire alarm equipment and shouldn't be left in the off position it might have a trouble circuit connected to the fire alarm panel. A trouble alarm on a fire alarm panel is different from an alarm circuit alarm.
