Abstract
A device and method for adjusting the height at which an alarm pull-station may be actuated. The device and method involve the use of a mechanical system in mechanical communication with an alarm pull-station. The height at which existing alarm pull-stations may be actuated is decreased without structurally, mechanically or electronically altering existing pull-stations. The device for adjusting the height at which an alarm pull-station may be actuated includes an alarm trigger operatively engageable with an alarm trigger lever of the pull-station, a rod operatively associated with the alarm trigger, and a mounting portion operatively associated with the rod, wherein the mounting portion is attached to a fixed structure and the device is disposed externally of the alarm pull-station. A spring is used between elements of the device to inhibit any unwanted downward movement of the device. Two spacers are used to engage a cover on the device to prevented unwanted withdrawal of the installed device from the alarm pull-station.
