Audited Supplier How does a security siren work?
Siren alarm systems work by generating a loud, piercing siren sound when they're triggered by intruders in and around your home. When they're set off, some siren alarms also emit flashing lights to attract even more attention to your property.

An alarm siren is a critical component of security and safety systems, designed to produce loud and attention-grabbing sounds when activated. These sirens are used in various applications, including security systems, fire alarms, emergency notifications, and vehicle alarms. The features of an alarm siren may vary depending on its intended use and the specific model, but here are some common features you might find in alarm sirens:
Loud Sound Output: Alarm sirens are known for their loud and piercing sound output, which is designed to alert and grab the attention of people in the vicinity. Sound levels can range from 90 decibels (dB) for indoor alarms to 120 dB or higher for outdoor and industrial applications.
Adjustable Sound Levels: Some alarm sirens allow you to adjust the sound level to suit the environment or the specific application. This can be useful to avoid excessive noise in quieter settings.
Tone Variations: Many alarm sirens offer multiple tone options. Different tones can be used to indicate various types of emergencies or events, such as fire, intrusion, or severe weather.
Strobe Lights: In addition to audible alerts, some alarm sirens are equipped with strobe lights or visual indicators. These lights can provide a visual alert for individuals who may have hearing impairments or in situations with high ambient noise.
Dual-Tone Sirens: Some sirens can produce dual tones, often referred to as "yelp" or "warble" patterns. These variations in sound can be more attention-grabbing than a continuous tone.
Wireless Connectivity: Modern alarm sirens may have wireless connectivity options, allowing them to be integrated into larger security or home automation systems. They can be remotely controlled and triggered by sensors or alarms.
Weather Resistance: Sirens used in outdoor applications are typically weather-resistant or weatherproof to withstand exposure to the elements.
Tamper Detection: Some alarm sirens have tamper detection features to alert you if the siren is tampered with or removed from its mounting location.
