The key functions of release warning lamps include:

Alarm Indication:
When a fire suppression system is triggered, either automatically or manually, the release warning lamp is activated to alert building occupants and emergency responders that the system has been or will be discharged.

Evacuation Notification:
The illumination of the release warning lamp serves as a visual cue for building occupants to evacuate the area immediately, as the discharge of the fire suppression system can pose a safety hazard.

System Status Monitoring:
Release warning lamps are often integrated into the fire alarm control panel or a dedicated annunciator, providing a centralized indication of the fire suppression system's status.

Placement and Visibility:
These lamps are strategically positioned in locations where they can be easily seen by occupants, such as near the fire suppression system's discharge points or along evacuation routes.

Power Supply:
Release warning lamps are typically powered by the fire alarm control panel, drawing their electrical power from the system's supervised circuits.

Maintenance and Testing:
Regular inspection, functional testing, and replacement of release warning lamps are essential to ensure their reliable operation in the event of a fire suppression system activation.
