Understanding The Process Of Commercial Fire Alarm Testing

Posted on

Commercial fire alarm systems play a critical role in protecting lives, assets, and property. These systems provide early warnings in case of fire, allowing occupants to evacuate the premises safely and timely. To ensure their reliability, these systems must be regularly tested. Here's how commercial fire alarm testing is conducted.

Initiating the Testing

Before any testing begins, it is important to alert the local fire department and the alarm monitoring company to avoid triggering a false alarm. Additionally, building occupants should also be informed about the scheduled testing to prevent unnecessary panic.

Visual and Physical Inspection

The testing process begins with a visual and physical inspection of all components of the alarm system. This includes control panels, pull stations, smoke detectors, heat detectors, audible and visual alarms, and auxiliary functions. 

The inspector checks for any physical damage, obstructions, paint or dust accumulation, or any other issue that might hinder the alarm's operation.

Functional Testing

Once the visual inspection is complete, a functional test is conducted. For manual pull stations, this involves physically activating the device to ensure it triggers the alarm. Smoke detectors are typically tested using canned smoke or a specialized smoke detector tester, which simulates smoke particles to trigger the detector. 

Heat detectors are tested using a heat gun to ensure they activate at the correct temperature.

Audible and Visual Alarm Testing

Audible alarms and strobe lights are tested to ensure they are loud enough and bright enough to alert all occupants in the event of a fire. For large buildings, this test is typically performed in sections to ensure every area is covered.

Control Panel Inspection

The fire alarm control panel serves as the system's brain, receiving signals from detectors and initiating alarms. During testing, each alarm signal is confirmed at the control panel. Additionally, the panel's power supply, backup batteries, fuses, and interfaces are inspected to ensure proper operation.

Communication Interface Testing

Many fire alarm systems are connected to a monitoring service or the local fire department. A test signal is sent to ensure the communication interface is working correctly, and the signal is being received.

Restoring the System and Reporting

After all tests are completed, the system is reset, and all activated devices are returned to their normal state. A report is then compiled detailing the inspection and testing procedures, results, and any necessary maintenance or repairs. This report is crucial for code compliance and insurance purposes.
