A fire alarm pull rank is an active fire protection device, usually wall-mounted, that, when activated, initiates an alarm on a fire alarm system. In its simplest form, the user activates the alarm by pulling the handle down, which completes a circuit and mane the handle in the activated position, sending an alarm to the fire alarm control panel. After operation, fire alarm pull stations must be restored to the ready position using a special tool or key in order to deactivate the alarm sequence and return the system to normal. Primitive manual stations requiring only a single action or hand motion to activate, can be subject to unwanted activation by jarring or accidental contact. Early strategies to cope with this conundrum included requiring the operator to break a pane of glass to release an internal spring operated means. Manual pull stations that demand two hand motions such as; lift up and pull down or push in and pull down have since replaced the break glass and single action models in many modern installations.
In Europe, Australia, New Zealand, and Asia, pull stations are generally not used; instead a manual call point is used, which is usually referred to as an MCP within the fire protection industry, as a "transmitter" in Japan, or as a "break glass" by the UK public. They are used to allow building occupants to signal that a fire or other emergency exists within the building. They are usually connected to a central fire alarm panel which is in turn connected to an alarm system in the building, and often to a local fire brigade dispatcher as well. The first modern MCP arrived in Europe in 1972 and was developed by KAC.[1]
the fire Alarm call points recieve the emergency calls and then the pull stations get a call of the call points to tell them were to go and stuff.
