Digital Security Controls SD-15WULF 15 W Dual-Tone Surface-Mount Siren

Provide audible alarm indication where an intrusion, access-control, or other physical-security system needs an attention-getting local sounder. This 15 W unit produces a dual-tone alarm signal and mounts directly to a surface, making it suited to protected interior areas where an audible alert must be heard near the event or alarm panel location. Surface mounting supports installation on a suitable wall, ceiling, enclosure, or other fixed structure selected for the protected area. The dual-tone operation differentiates the alarm sound from ordinary single-pitch audible devices and gives installers a defined signaling characteristic for the site. Its UL designation supports deployments that require this product designation as part of the alarm-device selection. Digital Security Controls SD-15WULF combines three specific selection points: 15 W audible output, dual-tone signaling, and surface mounting. Choose it when those characteristics match the system design and the installation location. Electrical connection details, mounting hardware requirements, and alarm-panel compatibility should be determined for the specific security system before installation.
