To confirm your IOTA ILBHI SP 2H HE SD HV emergency lighting equipment is functioning properly, consider these steps:
Automatic Testing: The unit conducts self-tests monthly (60 seconds) and annually (120 minutes). These tests work with the Threaded Body Test Switch (TBTS). A flashing bi-color indicates any failures; consult Table A in the manual for specific diagnostic codes.
Manual Testing: To manually test, press and hold the TBTS button for two seconds. Only initiate the test when the TBTS status indicator light is GREEN. The test runs for 60 seconds and can be stopped by holding the TBTS button for two seconds during the test.
Load Calibration: This is necessary when the LED load changes. Calibration occurs automatically 48 hours after installation. To manually initiate it sooner, hold the TBTS button for 20 seconds. Failures during calibration will be shown on the TBTS.
Maintenance: Always power down the battery circuit before maintenance. Disconnect AC power and the battery circuit, following manual instructions. After maintenance, reconnect the TBTS and restore AC power to the emergency luminaire.
Following these testing and maintenance guidelines from your IOTA ILBHI SP 2H HE SD HV manual will help ensure your emergency lighting is operational when needed.
