A longtime school maintenance worker has improved a Palo Alto campus alert system for use during emergencies, according to Palo Alto Weekly.
Teachers currently must use colored pieces of paper to indicate to first responders how things are transpiring in their classrooms: red for bad and green for good.
Mike Jacobs' "Safeguard Notifier" is a digital update for the old-school technology that replaces the paper cards with LED lights. If something goes awry, a teacher can hit a button on a key chain or lanyard that locks the doors and puts out the necessary light.
The system is not in place yet -- Jacobs is looking to raise money to spread the innovation around.
