Mircom MS-404U

The Mircom MS-404U is a non-coded, single-action emergency manual station finished in bright yellow enamel for quick visual identification, distinct from standard red fire alarm pull stations. Built from extruded aluminum, pulling the handle releases both a normally open and a normally closed switch, making it suited for emergency door control or similar peripheral device release applications.
