At 2 p.m. Thursday, Patton State Hospital on East Highland Avenue between North Victoria and North Palm avenues will test four air horns used as an alert system for the large hospital campus. The horns will possibly be heard throughout the San Bernardino and Highland communities. It will only be a test, and there is no cause for alarm.
The test will consist of a 40-second horn blast at 2 p.m. and three 3-second horn blasts at 2:05 p.m.
