The UHPPOTE Wired Emergency Fire Alarm Station 9-28VDC Conventional Dual Action Manual Call Point is designed for conventional fire alarm systems. It features a key lock for added security and a dual action handle that activates the normally-open alarm switch when pushed in and then pulled down. The word "ACTIVATED" appears at the top in bright yellow when the handle is latched in the down position, with a portion of the handle protruding at the bottom as a visible flag. This call point cannot work alone and must be used with an alarm control panel. It is not UL-Certified.
