Abstract

A pull box (12) for an emergency alarm system is disclosed having a modular construction that accommodates one or more optional modules in order to provide a wide variety of possible configurations. Also, the basic design of the pull station (12) provides for its resetting without requiring a cover of the pull station to be open.
As part of the optional modules (41 and 42), the pull station may be configured to provide both local and general alarm signals, with the general alarm signal capable of being activated only by authorized personnel.
