The alarm sounded around 5 am, waking residents out of their sleep to evacuate the building.
VFD units found a single sprinkler head had activated and controlled a fire in the bedroom of one apartment, according to a statement from the City of Victoria.
Firefighters extinguished the fire with a minimal amount of water, which further reduced the damage in the apartment building.
VFD personnel immediately worked to ventilate the apartment and turned off the sprinkler system to minimize water damage.
Residents were able to re-enter their apartments around 6 a.m. No deaths or injuries have been reported.
The cause of the fire is currently under investigation.
