Title: VISUAL ALARM SYSTEM

Abstract

A vlsual alarm system, particularly a system incorporating a gas-fllled diode glow bulb, for indicating a minor alarm and also a major alarm is presented. In operation, the disclosed system responds to a signal indlcative of a caution condition by applying a d-c voltage across the glow bulb to induce a glow at one electrode. If a signal indicative of a critlcal condition is received, the system applies an a-c voltage across tbe glow bulb to produce a glow discharge at each electrode.
