Threaded Body Test Switch
The TBTS option provides a single component for testing the emergency ballast and indicating the charge status of the battery, but in a more compact housing than other test accessory options. In normal operation, the TBTS will serve as a lit indication that the battery pack is being charged. When the switch is pressed, the indicator light turns off, and the light fixture is forced into the emergency mode. The smaller threaded body of the TBTS offers simpler installation in fixtures where limited space prohibits the installation of a typical test switch and charge indicator. The TBTS is hard-wired to the emergency ballast during installation.
