ANSI manual fire alarm station plan symbol
US-style plan symbol for a manual fire alarm pull station, commonly a square with an F, at each exit.
In plain English
What does ANSI manual fire alarm station plan mean?
US plans mark manual pull stations with a square containing F or a pull-station shape, located within reach of each exit door. Single-action and double-action types are distinguished in the device schedule.
A simple example
The plan is used to check that pull stations are within the required distance of each exit and at the required height. Protective covers may be specified where malicious activation is a risk. The symbol does not show the action type or cover.
What the drawings help you do
Check location near each exit. Check covers where specified. The IEC manual call point is a break-glass or resettable push; the US pull station is operated by pulling a handle.
