High-Output 15W Dual-Tone Internal Security Siren and Sounder A high-performance, commercial-tier 15W internal security siren engineered to deliver intense acoustic deterrence and clear audible alerts during alarm events. Featuring a durable high-impact ABS plastic housing, low current consumption, and selectable dual-tone signaling (steady and warble), this rugged sounder mounts cleanly on walls or ceilings to provide authoritative audible coverage throughout commercial buildings, schools, and institutional facilities.
High-Volume Acoustic Notification for Definitive Life-Safety Alerts
When a security breach or duress event occurs, immediate and authoritative audible feedback is essential to alert facility occupants and deter intruders. Standard low-output buzzers can easily be masked by ambient office noise, HVAC systems, or industrial machinery. The SD15W Internal Sounder is engineered to pierce through high-background noise environments, delivering an unmistakable acoustic alert exactly when it matters most.
Driven by a high-efficiency 15-Watt compression element, this siren generates up to 110 dB of sound pressure at a 1-meter distance. Housed in a clean, low-profile white enclosure, it blends seamlessly into modern corporate interiors while maintaining total structural resilience. Designed with independent dual-frequency terminals, it allows integration technicians to configure distinct audible tones for separate system alerts—such as a steady tone for structural fires and a sharp warble tone for duress or intrusion breaches.
Key Performance Features
Intense 110 dB Audible Output: Powered by a 15-Watt driver that produces a commanding acoustic output, ensuring alarm events are easily heard across expansive warehouse floors, long school corridors, or dense multi-room office suites.
Selectable Dual-Tone Signaling Architecture: Built with separate electrical inputs to deliver two distinct, installer-configured audio profiles: a Steady High-Tone (ideal for fire or evacuation tracking) and a Yelp/Warble Frequency Sweep (ideal for burglar alarms and panic events).
High-Impact UV-Stabilized ABS Enclosure: Molded from premium, impact-resistant ABS plastic that guards internal components against physical tampering, incidental environmental impacts, and yellowing from indoor fluorescent lighting.
Low Current Draw Efficiency: Engineered to optimize acoustic conversion while drawing a modest 350 mA at 12V DC, minimizing the strain on auxiliary power supply modules (such as the HSM2300) during simultaneous multi-siren activations.
Versatile Surface Mounting Layout: Outfitted with an adjustable internal mounting bracket and convenient rear wire entry channels, allowing the unit to be mounted flat onto drywall surface points, concrete ceilings, or standard electrical back-boxes.
Seamless Alarm Panel Integration: Operates on standard 12V DC nominal current, making it fully plug-and-play compatible with premium alarm control panels, including the DSC PowerSeries Neo HS2064 and auxiliary relay setups.
Ideal Security Applications
Commercial Office Corridors: Strategic placement in central hallways to ensure instant building-wide notification during a localized break-in or emergency alert.
Retail Cash Vaults & Counting Rooms: Connecting directly to under-counter panic lines to provide immediate local acoustic disorientation during high-risk ambush scenarios.
Industrial Warehouses & Mechanical Rooms: Cutting through heavy ambient equipment noise to deliver unambiguous system status alerts to facility engineers.
