At CCTV Glasgow, we pride ourselves on being experts in the field of fire safety and alarm systems. Ensuring the safety of building occupants and assets is paramount, and one of the key components of this safety is the regular testing of fire alarm systems.
Key Takeaways:
- Fire alarm testing ensures the safety of building occupants and compliance with standards.
- There are different types of fire alarm tests, each with its own purpose.
- Regular inspections and tests are crucial for maintaining a safe environment.
- Modern fire alarm systems are software-driven and can be easily modified, but this also means they need thorough testing to ensure changes don’t introduce new issues.
Why Fire Alarm Testing is Essential
Fire alarm systems play a pivotal role in ensuring the safety of building occupants. Their primary function is to alert individuals of potential fire hazards, allowing them to evacuate promptly. But how can one be sure that these systems will work flawlessly when needed? This is where fire alarm testing comes into play.
Ensuring Safety of Building Occupants
A malfunctioning fire alarm system can lead to disastrous consequences. Regular testing ensures that the system will function correctly during an emergency, providing timely alerts to occupants.
Compliance with Standards
In the UK, fire alarm systems must comply with specific standards, such as the NFPA 72, the National Fire Alarm and Signalling Code. Regular testing ensures that systems remain compliant, avoiding potential legal repercussions.
Protecting Business Assets
Beyond the safety of individuals, fire alarm systems also play a role in protecting physical assets. A timely alert can prevent extensive damage, saving businesses significant repair and replacement costs.
Types of Fire Alarm Tests
Fire alarm testing isn’t a one-size-fits-all process. Different tests serve different purposes, ensuring comprehensive system functionality.
Testing the People and Their Response
Some tests aim to evaluate how people respond to fire alarms. These tests require individuals to treat the alarm as real, regardless of whether they know it’s a test in advance2.
Testing the Alarm Installation
Other tests focus on the alarm system itself, ensuring that all components, from the sounders to the sensors, function as they should.
What Happens During a Fire Alarm Inspection and Test
Understanding the testing process can help businesses prepare and ensure smooth execution.
Informing the Local Fire Department
Before any testing begins, the local fire department must be informed to avoid triggering a false alarm.
Testing All System Components
Fire safety technicians will test all parts of the system, from fire alarm panels and strobes to fire doors and elevators.
Specific Items to be Inspected and Tested
A comprehensive fire alarm test will include checks on:
- Smoke and heat detectors: Ensuring they detect and respond to threats.
- Annunciators and zones: Confirming they provide accurate location information.
- Batteries: Checking they can power the system during outages.
- Output relays and activations: Ensuring they trigger appropriate responses, like unlocking doors.
- Flow switches, tamper switch, and low-pressure alarms: Confirming they detect issues in sprinkler systems.
| Component | Purpose | Testing Frequency |
|---|---|---|
| Smoke Detectors | Detect smoke in the air | Monthly |
| Heat Detectors | Detect a rise in temperature | Bi-annually |
| Fire Doors | Prevent fire spread | Annually |
| Batteries | Power the system during outages | Annually |
| Annunciators | Provide location information | Annually |
Duration of Fire Alarm Inspection and Test
The time taken for a fire alarm inspection and test can vary based on several factors.
Factors Affecting Duration
The size of the facility and the complexity of the fire alarm system are the primary determinants of the testing duration. For instance, a small office might only require an hour, while a large multi-building facility could take several days.
Importance of Thoroughness
While it might be tempting to rush through the process, thorough testing is crucial. Cutting corners can lead to oversights, potentially compromising the safety of building occupants.
Employee Awareness and Preparation
For businesses, preparing employees for fire alarm tests is essential.
Familiarity with Fire Drill Procedures
Employees should be well-versed in the building’s fire drill procedures. This ensures orderly evacuations during real emergencies and tests.
Notification about Upcoming Tests
Before testing, employees should be informed. This minimises panic and confusion, especially if the test involves sounding the alarms.
Frequency of Fire Alarm Inspections and Tests
Regular testing is non-negotiable. But how often should these tests occur?
Annual and Biennial Tests
Every year, fire safety technicians must test fire alarm control panels, initiating devices, alarm communication equipment, and remote annunciators. Every two years, tests should also include sensitivity tests for smoke detection devices.
Ensuring Continued Reliability
Fire alarm systems, including alarms, strobe lights, and smoke detectors, are often the most effective way to alert everyone in a building of an emergency. Regular maintenance ensures their continued reliability and proper functionality.
Frequency of Fire Alarm Inspections and Tests
Ensuring the reliability and effectiveness of fire alarm systems requires regular inspections and tests. But how often should these tests occur?
British Standard BS 5839-6: 2019 Guidelines
According to the British Standard BS 5839-6: 2019, fire detection and fire alarm systems for buildings should undergo a fire alarm test weekly. This routine check ensures the system’s optimal performance for fire safety.
| Test Type | Frequency | Purpose |
|---|---|---|
| Weekly Test | Every week | Check the system’s operational status |
| In-depth Inspection | Every 6 months | Comprehensive system check by a fire alarm engineering company |
Types of Fire Alarm Systems
There are primarily two types of fire alarm systems:
- Manual Systems: These systems, such as break glass units, are installed at exit points in a building. They allow individuals to manually raise the alarm during emergencies.
- Automatic Systems: These systems detect environmental changes like heat, smoke, and carbon dioxide. Any significant change triggers the alarm automatically.
Conducting a Fire Alarm Test
To ensure the effectiveness of the test and the safety of the premises, certain steps should be followed:
- Preparation:
- Read the manufacturer’s instructions.
- Inform staff about the test.
- Conduct the test at a consistent time every week.
- If connected to an ARC (Alarm Receiving Centre), notify them and set the system to ‘test’ mode.
- Testing:
- Use a manual call point reset key for activating and resetting the manual call point.
- Activate a manual call point.
- Confirm the alarm sounds.
- Reset the manual call point and the fire alarm control panel.
- A different call point should be tested each week.
Fire Alarm Maintenance
Regular maintenance is crucial for the longevity and efficiency of a fire alarm system. The responsible individual, such as a property manager or fire warden, must ensure that a competent specialist conducts this maintenance. All maintenance activities should be recorded in a logbook.
Recording Fire Alarm Tests
A fire alarm logbook is essential for recording all maintenance, tests, and repairs. This logbook should always be on the premises and available for inspection by the Fire and Rescue Service (FRS).
| Logbook Entries | Purpose |
|---|---|
| Dates and times of alarms | Record genuine and practice alarms |
| Faults and actions taken | Document system issues and resolutions |
| Test dates | Track regular system tests |
| Service dates | Monitor system maintenance |
| System alterations | Note any changes to the system |
Preventing False Alarms
False alarms can be disruptive and reduce trust in the fire alarm system. To minimise them:
- Ensure the fire alarm type matches the building’s needs.
- Maintain the system regularly.
- Investigate all false alarms and take corrective action.
- Implement a filtering process to determine the cause of the alarm before alerting the fire brigade.
Common Mistakes During Weekly Tests
Avoiding common pitfalls ensures the effectiveness of weekly tests:
- Not having the reset key or code for the fire alarm control panel.
- Testing the same call point repeatedly.
- Not documenting the test in the fire alarm logbook.
- Forgetting to remove the test key.
- Relying solely on the ‘evacuate’ button on the main control panel.
- Not having backup batteries.
