Combined sounder and visual alarm device plan symbol
Plan symbol for a fire alarm device combining an audible sounder with a flashing visual alarm.
In plain English
What does Combined sounder and visual alarm device plan mean?
Combined sounder and visual alarm devices give both a tone and a flashing light, for areas where people may be hard of hearing, wear ear protection or work in high noise. Plans draw the sounder form with radiating light marks.
A simple example
Visual devices have a coverage volume defined by product category and mounting, so placement is checked against the coverage data. The plan should tag the category or coverage code. The symbol does not show flash rate or colour. Product data and the applicable standard define these.
What the drawings help you do
Check coverage volume for the visual element. Check where deaf or hard-of-hearing occupants are expected. A flashing beacon in a control system gives an equipment status signal; this device is a life-safety alarm.

How to read it
- Check coverage volume for the visual element.
- Check where deaf or hard-of-hearing occupants are expected.
Information to show or reference
- Tag coverage category.
- Tag circuit or loop address.
- Confirm synchronisation of flashes.
A distinction that matters
A flashing beacon in a control system gives an equipment status signal; this device is a life-safety alarm.
