The sleek design of the alarm features a user friendly touch pad with colored LED indicators for easy visual detection. The alarm horn and red LED indicator activate for a high level alarm condition. The alarm horn and yellow LED indicator activate for alarm 2. The green LED indicates 120V primary power to the alarm. Once the condition is cleared, the alarm automatically resets.
