Light-emitting system:

Uses two systems: button battery or DC power supply input. The LED-lamp status display and the 7-segment display in the surge counter light up.If the unit is only powered by a button battery, the status display will light up for several seconds when you press the "SWITCH" status light-up utton.

When running on a DC power supply input, the status display will be lit all the time. In addition, if you are using multiple HOWL2 units, you can wire them in parallel to a DC power supply. (Power consumption approx. 80 mA per unit)

Additional functions for use in insulation testing:

Please remove the TEST PLUG from the front of the HOWL2 before you test the insulation of fire alarm systems. This will suppress SPD electrical discharges and meet the specified values during the tests.

Be sure to put the TEST PLUG back in its original place after finishing insulation testing. To prevent you from forgetting to put the test plug back, an alarm will sound when the HOWL2 is operated without its plug in place.

Multiple cores:

Even though the HOWL2 is small and compact, its cable can have 10 core wires.Must be installed by a qualified person.

Flexibility in mounting:

Even though the HOWL2 is small and compact, its cable can have 10 core wires.

The special adapter attaches to the HOWL2.
