Emergency Test Switch
Emergency Test Switch Overview
The Emergency Test Switch can monitor up to 5 lighting circuits and triggers a relay/contactor if any of the monitored lines fail. The device also has a key input which is used to start and stop emergency tests by triggering the relay/contactor.
The buttons on the Emergency Test Switch are used for commissioning purposes (i.e. Enable/Disable Prolong, Set Duration Time, Enable/Disable Monitoring Lines).
Multiple Emergency Test Switches can also be used together by connecting the devices via interlinking cables. This feature will only monitor interconnected fault conditions and is not triggered if the device is in a test. The table to the right shows where this product is typically used.
