Model 450E electronic horn offers a loud, clear and distinctive tone. It’s often used for general alarming, start and dismissal noticing, coded paging and process control in noisy areas. Its 4-wire terminal block and supervisory diodes design make it ideal for fire alarm applications.

The 450E’s polycarbonate housing and polymeric speaker are corrosion resistant and weatherproof for improved durability in harsh industrial environments. It has no detectable RF emissions in a 30 MHz to 1000 MHz frequency range, which minimizes the potential for electrical device interference.
