The Wheelock Series ET Vandal Resistant speakers and speaker strobes provide a full range of rugged, high performance combinations specifially designed to meet the critical needs of the life safety industry for voice and tone signaling. Available in compact, aesthetically pleasing package styles, each ET model covers both 25 and 70 volt audio systems, and has multiple wattage taps from 1/8 to 8 watts. Their high-efficiency design provides improved voice clarity and higher sound output for typical low frequency fire evacuation signal, such as the "slow whoop" and "temporal code-3".
