The ALARM CONTROLS CORPORATION 30203 is a weatherproof back box designed to protect access control hardware from moisture, dust, and outdoor environmental exposure. It serves as a protective enclosure for compatible lock control components, mounting to door frames or wall surfaces in installations where exposed elements need a sealed housing. The 30203 is appropriate for both new installations and retrofit projects where outdoor-rated protection is required. Licensed locksmiths, security technicians, and access control installers are the typical trades that work with this component.
The 30203 is suited for commercial and light-industrial access control systems where control hardware is mounted in exterior or high-humidity locations. Typical applications include entry points exposed to rain, condensation, or wash-down environments. It is sold individually and classified under lock accessories.
Designed as an OEM-style replacement or accessory back box for access control lock hardware requiring weatherproof outdoor-rated enclosures.
Installation is typically performed by a licensed locksmith or certified access control technician. Disconnect and de-energize all associated control circuits before beginning any mounting or wiring work. Ensure the mounting surface is structurally sound and that all conduit entries are properly sealed to maintain the weatherproof rating. Follow applicable local codes and manufacturer guidelines for exterior electrical enclosure installations.
