Alarmed Touch Bars for Emergency Exits

An alarm sounds when these touch bars are pushed to open doors. Often used on emergency exits, they require a lock cylinder (sold separately) to arm and disarm the alarm. You can mount an additional lock cylinder on the exterior of the door to use as a door lock.
