The addressable VULCAN 2 A is available as an Addressable Beacon, which can be field-configured to operate in either SHADOW or AUXILIARY mode. Versions with an integrated loop isolator are also available. Depending on loop loading, up to 64 VULCAN 2 A Beacon devices can be connected to a single loop. All VULCAN 2 A devices feature DIP-switch address setting, while tone and mode selection is configured via a jumper. A potentiometer is provided to adjust the sound level if required. The VULCAN 2 A is typically used in conjunction with a detector, though an optional lid is available.
Shadow Beacon: A Shadow Beacon does not have its own address, which frees up addresses for additional detection devices. Shadow Beacons do not report back to the control panel and are therefore not monitored on the loop.
Auxiliary Beacon: When configured as an Auxiliary Beacon, the VULCAN 2 A shares the same address as the associated detector. In this mode, it monitors the address loop for commands from the control panel to the detector. When the detector is activated, the VULCAN 2 A illuminates its LED accordingly.
In the event of a confirmed fire, remaining sounders can be activated using the Evacuate command. This approach provides early warning to the room occupant while minimizing disruption to other guests in the event of a false alarm. Pressing Sounder Silence at the panel silences all active sounders. The maximum number of Auxiliary Beacons is 63, which can be assigned to addresses 1 through 63.
