Commercial Fire Alarm Testing: What to Expect on Test Day
A well-planned fire alarm test is quick and low-drama. Here is what happens and how to prepare.
1.Monitoring is placed on test
Before testing, the technician notifies the central station so alarms are not dispatched to the fire department.
2.Tenants are notified
Occupants should know when horns and strobes will sound. Healthcare and occupied sites often test in phases or after hours.
3.Initiating devices are tested
Smoke detectors, heat detectors, pull stations, duct detectors, and waterflow and tamper switches are activated to confirm the panel receives each signal.
4.Notification appliances are verified
Horns, strobes, and speakers are checked for operation and audibility.

7.Monitoring is restored
The technician confirms the central station is receiving signals normally before leaving.
