Office Building Emergency
Alert System

Lyft, Inc., a leading American ride-hailing and mobility company, required a dependable on-premise emergency alert system to enhance safety and intruder response protocols at its 25,000-square-foot headquarters in San Francisco, CA. The office building emergency alert system needed to provide rapid, facility-wide notifications during critical situations such as intruder alerts, active shooter events, and other emergencies. To meet Lyft’s security objectives, the system was expected to deliver the following essential capabilities:

Visiplex’s wireless office building emergency alert system was successfully deployed at Lyft’s San Francisco headquarters using a centralized wireless paging base station and strategically placed emergency pull stations throughout the facility. Each pull station was pre-programmed to instantly trigger a specific, pre-recorded emergency voice message over the building’s PA system and activate corresponding color-coded beacon lights, providing clear, visual identification for events such as Lockdown, Evacuation, Severe Weather, and Fire.

The system included a network of wireless audio-visual PA speakers that delivered reliable, intelligible voice alerts across all areas of the building. Integrated multi-color beacon lights enhanced visibility and ensured ADA compliance, making alerts easily noticeable even in noisy or high-traffic environments.

All Visiplex components featured built-in battery backup, ensuring continuous emergency communication during power outages or electrical disruptions.

Beyond emergency use, the system also supports daily routine paging and facility-wide announcements, helping improve internal communication and operational efficiency.

Thanks to its modular, wireless design, Lyft’s in-house technical team was able to complete installation without the need for complex wiring or major infrastructure changes.
