Notifier Conventional Manual Fire Alarm Pull Stations

The NBG-12 manual pull stations 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 sta- tion, provided for non-English-speaking  people.

Pushing in and then pulling down on the handle activates the normally-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 or hex (model dependent), 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.
