The manual call points provide a textured finger-hold area that includes Braille text. In addition to PUSH IN and PULL DOWN text, there are arrows indicating how to operate the station, provided for non-English-speaking people.
Pushing in and then pulling down on the handle activates the noramlly-open alarm switch. Once latched in the down position , the word" ACTIVATED" appears at the top in bright yellow, with a portion of the handle protruding at the bottom as a visible flag.
Resetting the station is simple: insert the key, twist one quarter-turn, then open the station"s front cover, causing the spring-loaded operation handle to return to its original position. The alarm switch can then be reset to its normal(non-alarm) position manually(by hand) or by closing the station"s front cover, which automatically resets the switch.
