ECL-230D Exit Control Lock by Detex

Code compliant, battery alarmed, rugged panic hardware with deadbolt provides managed security for secondary exits. Ideal for us with emergency exit doors in restaurants, retail shops, department stores, grocery stores, discount stores, stock rooms, warehouses, factories, airports, hotels, office buildings, municipal buildings, and government facilities.
When armed, pressing the exit bar retracts the deadbolt and sounds the alarm to allow exit. An authorized key simultaneously projects the bolt, secures the door and resets the alarm.
