Vault ceiling alarm

The Vault ceiling alarm is a type of warning device used for alerting residents of threats. This alarm is a ceiling-mounted circular device located in the corridors of Vault 101. The alarm has a strobe lamp which glows red and sweeps the immediate area during an emergency. A second lamp, nestled in the bottom of the alarm, glows white. Finally, the alarm has a klaxon for sending a loud noise for attention.

On August 17, 2277, these alarms were activated by Overseer Alphonse Almodovar. He activates the alarms in response to a successful escape attempt by the Vault Physician James, subsequently followed up by a radroach infestion.
