120dB Self-Contained Alarm Siren with 25W Speaker, IP65 Weatherproof Housing, Built-In Tamper Protection, and Surface or Gang Box Mounting for Indoor and Outdoor Security Installations
The Seco-Larm SH-816S-BQ is a 120dB self-contained alarm siren with an integrated 25W speaker that combines high-output warble-tone alerting and audio broadcasting in a single IP65-rated enclosure for indoor and outdoor security installations. The SH-816S-BQ operates on 9 to 15 VDC with a maximum current draw of 870mA, mounts to wall surfaces or standard gang boxes, and includes built-in tamper protection that triggers an output when the housing is opened or removed.
The SH-816S-BQ serves dual roles as both a siren and a public address speaker, accepting broadcast audio input alongside its built-in warble-tone generator. The broadcast input interrupts siren output during use, allowing voice announcements to override the alarm tone. At 6-1/8 x 4-15/16 x 4-1/2 inches, the compact enclosure fits standard outdoor alarm installations while the IP65 rating protects against water jets and dust ingress for reliable year-round operation.
Where the SH-816S-BQ Fits
- Perimeter security and outdoor alarm installations where the 120dB warble-tone siren provides audible deterrence across large areas, the IP65-rated housing withstands rain, dust, and temperature extremes, and surface or gang box mounting options adapt to walls, fences, and building exteriors
- Commercial and industrial alarm panel integration where the 9 to 15 VDC operating range connects directly to alarm panel siren outputs, built-in tamper protection feeds back to the panel when the housing is disturbed, and the 870mA maximum draw stays within standard alarm panel current budgets
- Combined siren and public address applications where the 25W speaker accepts broadcast audio input for voice announcements and emergency instructions, the broadcast input overrides the siren tone during use, and the single-unit design eliminates the need for separate siren and speaker installations
What the SH-816S-BQ Delivers
- 120dB Warble-Tone Siren: Built-in warble-tone generator produces 120dB output for effective audible alerting across large indoor and outdoor spaces. The high-output siren provides the deterrence volume required for commercial and industrial security installations.
- 25W Integrated Speaker: 25-watt peak speaker accepts broadcast audio input for voice announcements, emergency instructions, and public address functions. Broadcast input interrupts siren output during use, enabling voice-over-alarm capability from a single device.
- IP65 Weatherproof Housing: IP65-rated enclosure protects against water jets and dust ingress for reliable outdoor operation in all weather conditions. The compact 6-1/8 x 4-15/16 x 4-1/2 inch housing mounts to wall surfaces or standard single and double gang boxes.
- Built-In Tamper Protection: Tamper output rated at 100mA at 30V AC/DC triggers when the housing is opened or removed from its mount. The tamper circuit connects to alarm panel tamper zones for immediate notification of physical interference with the siren.
