I-Force Siren


American Signal Corporation's I-Force Siren is a High Powered Speaker Array (HSPA) that is fully configurable from a directional 900 to fully omnidirectional 3600 sound propagation patterns for high power speech intelligibility. The I-Force Sirens are battery operated electronic outdoor warning devices that are capable of multiple warning signals and high-powered voice communications. These units can be triggered locally and/or remotely via SMS, radio, DTMF telephone, or satellite.


I-FORCE Sirens are designed for community, Industrial nuclear, petrochemical, or other applications that require high levels of sound pressure level output with superb acoustical performance and brilliant voice notification broadcasting.


Siren output ranges from 115dB for the IForce-1600 through to 126dB for the IForce-3200 model.

Configurations include omni-directional or quadrants for 900-3600 coverage patterns. The colour impregnated fibreglass siren horns are able to endure severe weather conditions, are maintenance free and will not rust or require painting. The Electronic Controls have a self-contained, regulated battery charging system that assures full siren operation during AC outages.

The IForce-3200 siren provides a sound pressure level of 70dB for approximately 1.6km (radial), subject to weather conditions.

Evacuation sirens provide the best form of public warning, potentially reaching the most personnel in danger - not everybody on-site has access to radio, phone or in-building Public Address to warn them of the danger.

Applications for these sirens include:

  • Emergency Services
  • Nuclear and chemical accident warning
  • Military Bases for Personnel Alert Systems
  • Golf Courses Lightning/Storm Warning and Announcements
  • Amusement Parks
  • Colleges / Universities
  • Industrial Employee Evacuation Systems
