Detectomat EX4A4ex 4 Zone Ex Environment Detector Expansion Card

The EX4A4ex card adds four detector zones operating in explosive atmospheres to the ALPHA fire alarm control panel. Since each zone has its own alarm and fault LED as well as a test button, the status is read directly from the card. It is used in the protection of Ex zones such as paint shops, fuel filling areas, and chemical storage rooms. Thanks to the test button, each zone can be individually tested during periodic inspections and record-keeping becomes easier.
