Problems solved by technology

These friction elements typically wear over time and are susceptible to the accumulation of dirt, dust, and debris that can affect the functionality of the pull station and require additional force for actuation
Also, the elements in conventional pull stations are easily removable and do not provide a mechanism for distinguishing between accidental and intentional actuation
As a result, such pull alarms have limited reliability

Embodiment Construction

[0026] figure 1 An example of a building 20 including a fire alarm system 30 is shown in FIG. Fire alarm system 30 includes a plurality of manually operable pull alarm devices 32 positioned at various locations throughout building 20 . A plurality of pull stations 32 are operably coupled to each other, such as via a plurality of wires or a controller (not shown). As a result, if one of the plurality of pull stations 32 is actuated to indicate the occurrence of a predetermined emergency such as a fire, one or more of the unactuated pull stations 32 in other areas of the building 20 will It may be configured to generate an alarm throughout all or at least a portion of the building 20 .

[0027] now refer to figure 2 , showing in more detail the construction for the figure 1 An example of a pull station 32 used in a fire alarm system 30 of FIG. Although pull station 32 is shown and described herein with respect to fire alarm system 30 , pull station configurations for use i...

Abstract

The invention provides a hand-pull alarm device push plate. The hand-pull alarm device push plate includes a shell as well as a movable component and a hand-pull alarm device which are arranged in the shell, wherein the movable component can move between a first position and a second position. Only the application of a stable force to the movable component can make the movable component move between the first position and the second position.

Description

technical field [0001] The present disclosure relates to pull-stations for use in alarm systems, and more particularly, to manually-operable pull-stations that can be actuated and subsequently reset. Background technique [0002] Fire alarm systems often incorporate one or more manually operable pull sirens, which can be activated by a person discovering the fire to set off the fire alarm. Such pull stations traditionally include elements that are accessible through a window. To activate the fire alarm system, force is applied to the element causing the element to move and engage an adjacent switch. The status of the pull station can easily be determined visually by a simple visual assessment of the condition of the element. [0003] Conventional pull alarm devices usually include a plurality of friction elements. Similarly, there are other means configured to constrain movement of the element once actuated. These friction elements typically wear over time and are suscep...
