Sounder & Flasher

Key Features

1. Dual Functionality:

   • Combines both audible (sound) and visual (flashing light) alarms in one device for enhanced alerting capabilities.

2. Adjustable Sound Levels:

   • Sound output can typically be adjusted to suit the environment, with a range of volumes to ensure the alarm is heard clearly in various spaces (typically 90 dB to 120 dB at 1 meter).

3. Flash Rate:

   • Flashing light is synchronized with the alarm, with a typical flash rate of 1-2 flashes per second, providing a clear visual alert.

4. Strobe Light:

   • A bright strobe or LED light, often available in multiple colors (red, amber, or white), is used to visually signal a fire alarm condition.

5. Wide Operating Voltage:

   • Operates within a wide voltage range (usually 12V to 24V DC), making it compatible with a variety of fire alarm systems.

6. IP Rating:

   • Available in weatherproof and explosion-proof versions, ensuring that the unit can be used in both indoor and outdoor applications, including hazardous environments.

7. Low Power Consumption:

   • Designed to consume minimal power, optimizing the fire alarm system’s overall energy use.

8. Simple Installation:

   • Easily mountable on walls or ceilings, compatible with existing fire alarm wiring and systems.

Applications

• Industrial and Commercial Spaces:
  Used in warehouses, factories, or any areas with high ambient noise levels where the audible sound alone may not be sufficient.

• Public Buildings:
  Ideal for schools, hospitals, malls, and office buildings to ensure the fire alarm is noticed by all.

• Hazardous Areas:
  For environments like chemical plants or refineries, where both sound and light are critical for worker safety.

• Residential Installations:
  Particularly useful in multi-level homes, apartments, or buildings where individuals may not hear a traditional alarm.

How It Works

1. Alarm Activation:

   • When a fire is detected by the fire alarm system, a signal is sent to the combined sounder and flasher.

2. Sound and Flash:

   • The unit immediately activates both the sounder and the flashing light, alerting people within the area to the fire.

3. Continuous Operation:

   • The device continues to sound and flash until the fire alarm is reset or deactivated, signaling that the danger has passed.

Maintenance

1. Regular Testing:

   • Check the sound output and flash rate to ensure both are functioning properly.
   • Perform tests monthly or as recommended by local fire regulations.

2. Cleaning:

   • Periodically clean the lens of the flasher and the speaker of the sounder to remove dust or debris that could hinder performance.

3. Battery Check:

   • If the unit operates on backup batteries, ensure that the batteries are in good condition and replace them as needed.

4. Inspection:

   • Inspect the unit for any physical damage to the casing, light, or speaker. Replace damaged components promptly.

Advantages

1. Enhanced Visibility:

   • The combined visual and auditory alerts make it easy to detect a fire alarm, even in noisy or visually cluttered environments.

2. Increased Safety:

   • Helps to ensure that people with hearing impairments or those in loud environments can be effectively alerted to fire emergencies.

3. Versatility:

   • Suitable for a wide range of settings, from industrial to residential applications.

4. Cost-Effective:

   • Combines two critical alarm functions into one unit, reducing the need for separate sounders and flashers, simplifying installation, and saving on equipment costs.
