SiSA Outdoor Giant Voice Siren
SiRcom USA offers breakthrough clear speech technology embedded in a high power speaker array (HPSA). SiRcom can upgrade your existing outdoor HPSA or design a new system to cover your campus, base, or facility outdoor areas with siren tones and clear voice messages.
Cost Effective: Users can easily upgrade their system as needed or leverage existing infrastructure
Secure: Software is certified to be behind Department of Defense firewalls, making this system one of the safest and most secure options available
Innovative Speech Technology: Dynamic, clear speech technology provides clearly annunciated notifications that can easily be heard over siren systems
Reliable: IP solution offers a reliable option that isn’t limited by WiFi connectivity; system includes battery backup and is continually monitored
Modern Design: Lightweight, aerodynamic design is easy to install and withstands wind gusts
Description
- Higher intelligibility: SiRcom’s vertical line arrays provide a narrow vertical output pattern for focusing sound at audiences, without wasting output energy on the floor and up in the air; the more narrow the beam, the less distortion due to reflections, resulting in higher intelligibility
- Equalized intelligibility: Vertical line arrays approximate a line source of sound, creating a nearly cylindrical sound propagation pattern, resulting in balanced sound power output; messages are clearly heard at 100 feet as well as 1,500 feet
- Directing sound where you need it: Our speakers can be mounted for omni-directional and directional speaker coverage
- Intelligibility ratings: 0.8 Common Intelligibility Scale (CIS) rating; Phonetically Balanced Word Score Test—better than 95%*
- Energy Efficient:
- Sirens only need one 150-watt driver per horn; two drivers needed for 360° coverage, equalling a fraction of the number of drivers required for traditional speaker system designs
- Utilizing Class D amplification technology and better power management, the SiRcom amplifier is over 90% efficient. This enables lower current draw and increased battery life. It also results in fewer speakers being required as well as significantly less power for a substantially larger range
