Product Code: FDME223
Call ButtonAdresli

FDME223 is a manual alarm button electronic unit with integrated line isolator and LED indicator. Two-color LED distinguishes alarm from test condition. A short circuit in the supply line does not drop the entire circuit thanks to the integrated isolator; only the faulty section is deactivated. Used together with FDMH293-R housing and forms the basis of indoor fire button installations.
