Vandal and environment-resistant metal construction for outdoor or indoor use.


WASI -100 & WASO-100

Reflex projector Model WASO-100 and WASO-100 are for directional sound and signaling distribution where wide-angle dispersion and maximum audibility are required.

industrial communications systems

WASI-30-T & WASI-15-T

The WASI-30-T & WASI–15-T environment-resistant loudspeakers provide high intelligibility voice and siren tone transmission in medium power indoor and outdoor industrial communications systems.


EXPL-60-T & EXPL-30-T

Tone Alert Radio

Our TAR-900 is a multi-mode alert radio that serves as the perfect solution for emergency communication and mass notification. Compatible with multiple communication methods and protocols, the TAR-900 provides the flexibility and reliability with multiple notification methods. The TAR-900 is the only alert radio capable of providing both a NOAA receiver coupled with a local receiver to allow localized control of escalating events. Or, choose from any of our available input and output channels, in any combination.

ISI (Interior System Interface)

The ISI (Interior System Interface) is a special adaptation of our Universal Remote Terminal Unit (U-RTU™). It is a wireless (VHF or UHF radios) or wired transceiver designed specifically to provide a simple way to interface the (Wide Area) Outdoor Emergency Warning System to interior systems. The primary purpose of the ISI is to provide a simple generic interface to almost any interior — paging system, emergency communication system, or voice type fire alarm system used for Mass Notification.
