## Symbol convention

Convention: IEC
Form: Manual call point
IEC 60617 installation-plan style (architectural and topographical installation symbols); independently drawn, not certified IEC geometry or a database identifier.

Fire alarm plan symbol for a manual call point that occupants operate to raise the alarm, placed at exits.

## In plain English

### What does Manual call point plan mean?

Manual call points, often break-glass or resettable push units, are drawn as a square with a filled or crossed inner square, or a circle with a dot, at their wall position. They are placed at storey exits and exits to open air so a person leaving can raise the alarm.

### A simple example

Mounting height and travel distance to the nearest call point are set by the fire code. The plan allows inspectors to check these quickly.

### What the drawings help you do

The symbol does not show whether the unit is resettable or break-glass, or whether it has a protective cover. The schedule states this.

### This particular reference

Fire alarm plan symbol for a manual call point that occupants operate to raise the alarm, placed at exits. A bell push or assistance call button looks similar on a plan; the call point belongs to the fire alarm system.

## What it represents

The symbol does not show whether the unit is resettable or break-glass, or whether it has a protective cover. The schedule states this.

## How to read it

- Check positions at each exit.
- Check travel distance coverage.

## Information to show or reference

- Tag loop and address.
- State unit type and cover.
- Give mounting height.

## Important distinction

A bell push or assistance call button looks similar on a plan; the call point belongs to the fire alarm system.

## Facts

- Placement: Storey exits and final exits
- Operation: Break-glass or resettable element
