SF401-400 DIN Base Series / KMF 600

Industrial Static Filament Beacons

The SF401-400 DIN base series is suitable for security, process control and industrial applications where a more robust and powerful signal is required.

These beacons are of the Static mode type (single stage alarm). Once the beacon is energised the Incandescent / halogen lamp will stay permanently on.

An advantage of this type of beacon is that it can be controlled via a remote source (ie. control panel / plc etc ) giving the beacon greater flexibility and offering a (flashing) second stage alarm. The design allows for termination inside the enclosure through the base.
