Alarm Always On

A project log for Call Box

Pushing a button will sound a piercing alarm to alert a caregiver (in another room) that attention is required.

I needed to make the alarm "always on" so that it would sound (and continue to sound) on power up.

First, find the "test" switch."

Next, create a solder "bridge" across the switch terminals from the back side.
