Industrial 1430203 Electromagnetic Door Holder

The No Name / Industrial 1430203 Electromagnet Door Holder is an electromagnetic hold-open device that keeps fire-rated doors open during normal operation and releases automatically when a fire alarm is activated or power is lost. It offers wall-mount or floor-mount installation depending on the application and operates from a typical 24 VDC supply. Constructed with a steel housing and electromagnetic coil, it delivers an industrial-grade magnetic holding force and wears an industrial protective finish suitable for indoor commercial and industrial environments. Designed for fire alarm and life-safety systems, it is commonly used in fire door hold-open applications within hospitals, schools, offices, warehouses, and manufacturing facilities, and is compatible with fire alarm and access control systems. Maintenance teams and system integrators rely on it for repairs, replacements, retrofits, and upgrades to life-safety deployments. Common replacements include Dorma EM Electromagnetic Door Holder, Secu-ritron M62 Electromagnetic Door Holder, and Edwards 1504-AAQ Electromagnetic Door Holder.
