Circuit Blox™ - Alarm Block - E-Blox®

The alarm block clicked into our Circuit Blox set without any hassle, and the single-piece design makes it easy for small hands to manage. It's been a solid addition to our builds—works every time so far.

My kid's been building circuits for weeks and this alarm block finally gave his creations a sound effect. It clicks right into the other blocks and the buzzer is loud enough to hear from the next room.

Snapped this alarm block into our existing set and it clicked right in without any fuss. The buzzer is loud enough that my son actually uses it as a doorbell for his room now. Wish the set came with two of these instead of just one.
