Alarm sirens

Alarm sirens are used to create a loud, high-pitched sound in case of an emergency to alert a warning or attract help. Typically, an alarm siren is used in conjunction with an alarm system, such as a burglar or fire alarm, and is designed to alert the people in the vicinity to take action or evacuate. These loud devices can be triggered manually, such as a button, however they're also activated by smoke or motion. Browse our collection at B&Q today and feel safe in your space.
