In 1988, the Singapore Civil Defense Force (SCDF) began the search for a nationwide outdoor warning siren system. Throughout that year, they toured various siren companies across the world and in the United States. This included Whelen, Federal Signal, and Alerting Communicators of America to name a few. Ultimately, the SCDF would end up going with Hörmann for their siren system. The following photos are from the ACA tour.
