80dB Minimum Alarm Sound Audible-Visual Device For Conventional Fire Alarm System
Introduction
A sounder-flasher, also known as a combination sounder-strobe or audible-visual device is a type of fire alarm notification appliance that combines both audible and visual signaling capabilities. Here's a more detailed introduction to sounder-flashers:
Audible Signaling:
The sounder component of the device is responsible for producing an audible alarm, typically in the form of a siren, horn, or other loud sound.
The audible signal is designed to alert building occupants of the emergency and prompt them to evacuate the premises.
The volume and tone of the sounder are often adjustable to ensure the alarm can be heard clearly, even in noisy environments.
Visual Signaling:
The flasher or strobe component of the device is responsible for providing a visual alarm signal.
The strobe light, which typically flashes at a rate of 1-3 Hz, is intended to attract the attention of building occupants, particularly those who may have difficulty hearing the audible alarm.
The visual signal can be especially important for individuals who are hard of hearing or deaf, as it provides a supplementary means of alerting them to the emergency.
Integrated Design:
Sounder-flashers combine the audible and visual alarm capabilities into a single, integrated device.
This design helps to streamline the installation process and ensures that both audible and visual signals are consistently placed throughout the building.
Placement and Coverage:
Sounder-flashers are strategically placed throughout a building, often near exits, stairwells, and other common areas, to ensure adequate coverage and visibility.
The placement and quantity of sounder-flashers are typically determined by local fire codes and regulations to meet the specific needs of the building and its occupants.
Power Supply:
Sounder-flashers are typically connected to the building's fire alarm system, which provides the necessary power and control for their operation.
