IEC 62034 Automatic Test

According to HK FSD, Technical Guidance May 2021 and FSD Circular Letter No. 5/2021, PPA/104(A), 5th Revision, emergency lighting with self-contained batteries shall be inspected periodically. For automatic testing devices, it shall be designed in accordance with IEC 62034:2012 - Automatic test systems for battery powered emergency escape lighting.

Our test system will start automatically after mains supply is not interrupted for 5 days. After a random delay days for different device,  a commissioning test is started. This avoids adjacent devices testings at the same time. Monthly functional tests and annually duration test will then be repeated.

The firmware supports full IEC 62034 - ATS Type S, including the following tasks:

IEC 62034 

IEC 62034/BS EN 50172/FSD Requirements Automatic Test
Commissioning Testing

a. Once every month a functional test in accordance with BS EN 50172 not longer than 10% of rated duration should be carried out.

60 sec

b. Once every twelve months a full rated duration test, should be carried out and the results should be entered in a register.

c. The luminaire should be functioning properly to maintain the stipulated lighting level and the normal power supply should be restored after the test.

d. If automatic testing devices are used, the above item a – c should be complied with.


Functional and Duration Tests

Functional and duration tests are two types of tests performed to ensure exit sign functionality and reliability.

  • Functional test is performed once a month to check the basic functionality. The test also checks the hardware parameters, such as various voltage and current. The test duration is 60 seconds.
  • Duration tests are performed once a year. The tests is the same as functional test but with additional battery life check with a full rated battery discharge.
  • Commissioning test are the first duration tests. They are typically performed after the device has been installed and configured.


Test Performed Functional

1. System Changeover

2. Lamp voltage

3. Lamp current

4. RTC battery voltage

5. Battery charging voltage

6. Battery charging current

7. Battery discharging voltage

8. Battery discharge time


Automatic Test Flowchart

Network Configurations

1. Configuration with WiFi

    • Automatic upload test results to cloud
    • Automatic monthly monitoring and logging
    • Automatic test results reporting
    • Test results can be requested via app

2. Configuration without WiFi

    • Test results can be requested via app
    • Use mobile phone hotspot to sync test results
    • View test results and system status on app

App support

An Android app is available to simplify set up and maintenance. It helps

  • Set up new devices
  • Sync test results to cloud
  • Check test results and real time status
  • Use as Hoye IR remote controller

* An Android phone with an IR blaster is recommended. If not, a Hoye IR remote controller has to be used with the app.

Real Time Clock

  • The system has a coin battery powered real time clock (RTC)
  • The battery can last more than 10 years
  • The RTC provides accurate time and calendar for system and automatic test schedule
  • RTC is automatically calibrated with internet time

Records of Test Results

To ensure high reliability, all test results are saved in two sets of data backups:

  • Internal flash memory: This can store up to 20 years of data.
  • Cloud storage: The number of test results that can be stored in the cloud is virtually unlimited.

After an automatic test, the test result is saved to internal flash memory immediately. If a Wi-Fi connection is available, the data is also uploaded to the cloud.


ARM 32-bit Processor

The core of the system is controlled by an ARM 32-bit processor, which is more powerful and faster than previous generations.

System parameters, such as current and voltage from battery, charger and lamp, are sampled several thousand times per second. This provides fast and accurate response for system operations, fault monitoring and automatic test system.

Years Warranty

Hours of LED Life


LED Chips

The series incorporates best of best Nichia LEDs from Japan. The LEDs have the longest LED life and the best performance in the industry. They are IES lM-80-2008 (Measuring Lumen Maintenance of LED Light Sources) certified for the best reliability and performance. For eye safety, the LEDs are also IEC 62471:2008 (Photobiological Safety of Lamps and Lamp Systems) certificated.

IR Remote Control

The infrared remote control makes maintenance easier than ever. It can be used to set the LED exit sign system settings and self-test functions.

  • Panel brightness dimming control in normal operation
  • Flashing model in emergency mode
  • System changeover test (simulate traditional test button)
  • On-demand self-test

Status Indications

Two LED indicators provide a rich set of status indications for system status and faults. Operators can use the information to quickly identify and diagnose problems.


Normal Status

  • Charging
  • Battery charged
  • Functional test pending
  • Duration test pending


Fault Status

  • Battery fault
  • Lamp fault
  • Charger fault
