Cooper Notification’s WAVES (Wireless Audio Visual Emergency System) Autonomous Control Unit (ACU-340) is a supervised Individual Building Emergency Communications System, which provides supervised paging, background music, messaging, and emergency voice communications with 24 VDC battery backup. The ACU-340 is a UFC-compliant (Unified Facilities Criteria) Individual Building System, which provides full control of building notification appliances such as loudspeakers and strobe lights. The ACU-340, which includes a WAVES transceiver, interface, and antenna, can be controlled and monitored by a base-wide WAVES Mass Notification System (MNS). The WAVES base station can send messages to one ACU-340 or multiple ACUs and tie the indoor system to an outdoor MNS.

This single channel system is capable of delivering 40 watts of supervised high fidelity audio power and 2 amps of supervised 24 VDC synchronized strobe power. It comes standard with an on-board digital voice messaging system with 8 standard messages, a hand-held microphone, power supply/battery charger and numerous additional features. In a base-wide mass notification mode, the TRX-401 functions as the audio and data input/output link.

The ACU-340 is expandable to 5280 watts utilizing the ACU-PB80 (80 watts and 4 amps of strobe power), the ACU-PB160 (160 watts) or ACU-PB320 (320 watts) supervised audio power boosters. Additional expansion options include audio splitters, addressable paging splitter and telephone zone controller; supervised volume control and remote microphone; and a remote microphone expansion module.

The ACU-340 integrates with fire alarm systems and provides a signal for temporary deactivation of fire-alarm audible notification devices as required by UFC. The fire alarm system appliances are reactivated after the mass notification voice messages are delivered.

The ACU-340 also features real-time monitoring and reporting of all system components and is compatible with Cooper Notification power supply, speakers, strobes, and clusters.
