Product Details

Save valuable seconds on EMS response times!

The SC-911 Strobe Controller connects in parallel with your phone line and passively listens for touch-tones. When 911, 9-911, 8-911, or the custom activation number is detected, the SC-911 flashes the built-in 0.75” LED and activates a 12VDC switched output capable of running an emergency strobe light.

A strobe light can get help to you when you need it most, providing the emergency services with a clearly visible beacon to locate your home as fast as possible, and also alerting neighbors or nursing staff of your need for assistance.

The built-in LED is useful for indoor applications, such as apartment complexes, schools, offices and assisted living housing.

The SC-911 comes complete with a 12VDC power adapter, and also provides a set of relay contacts for user application.
