The operating voltage of the unit is stated on the unit label.
The beacon can be initiated directly when power is applied, if the local link between terminals 7 and 8 is connected.
Alternatively, the local link can be removed and a remote, voltage free contact can be connected to terminals 7 an d 8 in its
place. In this case, the beacon will only flash when power is connected to the terminals and the remote contact is closed.
