China Emergency Light Manufacturers - Self-Test Emergency Lighting: Test Items
Added: (Fri Mar 29 2019)
Pressbox (Press Release) -
According to the law, emergency lighting devices must be routinely tested. These tests should be documented and the results include all archived maintenance and rectification results. Recommendations for minimum test schedules are provided in relevant national standards.
Testing emergency lighting does not require much effort or difficulty, but checking the lamp startup, operation and duration of each lighting fixture can be labor intensive and therefore expensive. It also requires that each installation require multiple key switches to be located so that each fixture can be seen as each test is performed - this increases the cost of the initial installation and may reduce the aesthetics of the property.
Buying self-checking emergency lighting can bring many benefits, including reduced labor costs and time, and initial costs may be higher, but overall they provide a very short payback period, making it a choice to consider when starting a project. .
China Emergency Light Manufacturers explains the benefits of self-checking emergency light units:
• Easy to install - no need for key switches / data lines, etc.
• Convenient - Mandatory testing without disrupting the normal use of the building
• Due diligence - conduct automated tests and indicate failures
• Reduced maintenance - The self-test unit identifies faults in fixtures that require maintenance and then highlights any faults to maintenance personnel, saving them from searching for faults in the building
• Reduce wasted time - Save on personnel to check each emergency lighting fixture
• Interlaced testing - Luminaire testing will take place at different times, which means that any area is still protected in a real emergency.
• Cost savings - no dedicated staff is required to initiate testing and inspection of fixtures. Maintenance personnel only need to correct the fault and reset the system
The self-test unit uses a precise internal clock programming to interrupt the permanent mains supply at set intervals and initiate an emergency lighting test. The self-test unit provides 3 pre-programmed settings:
1) Perform a short-term test every week/month
3) Complete the test duration every 12 months (according to the recommendations of BS5266 and EN50172)
During the initial power-up of the self-test unit, the system will go through the commissioning phase - the internal clock will start at a random time between 0-24 hours, which avoids all of the lamps entering the test at the same time. After the initial charging time (usually between 48-72 hours), the device will be fully tested. Based on the results and assuming all results are satisfactory, the LED status indicator will show positive/health status. Once this is done, the internal microprocessor will initiate a standard programming test plan.
Manual testing of self-test emergency lighting units is still possible.
Monitoring results.
A single tri-color LED indicates system status:
• Health - The green LED is always on (pulse once per minute, indicating that the microprocessor is active and operating normally.
• Battery High/Low - Amber LED flashes and internal buzzer sounds for 10 seconds every 4 hours
• If the fault is cleared, the LED will return green.
During the test:
• Green LED is always on
• Pass the test - LED returns green
• Test failed - red LED flashes, internal buzzer sounds for 10 seconds
• every 4 hours
*Before the indicator returns to health, the fault must be corrected and manually retested (by pressing the test button)
