The SG-42SK Series replaces are single contact, key-reset, manual pull stations designed for use in fire alarm systems. They are constructed from a rugged, but lightweight, die-cast metal alloy for increased performance and longevity. The SK-42SK Series is available in single action (PULL lever) or dual action (PUSH bar and PULL lever) models. All SG-42SK Series models have been tested by UL and are in compliance with the pull force requirements of the Americans with Disabilities Act (ADA).
