GENERAL:
Wheelock's Series ET70/90 Low Profile Speakers and Speaker Strobes are UL Listed under Standard 1971 for Signaling Devices for the
Hearing Impaired and UL Standard 1480 for Speaker Appliances. They are designed for multiple power requirements with high dBA output
at each power tap. All models offer a choice of field selectable taps, 1/8W to 8W for either 25.0VRMS or 70.0VRMS audio systems. The
Low Profile design incorporates a high efficiency speaker for maximum output at minimum power across a frequency range of 400Hz to
4000Hz, and features a sealed back construction for extra protection and improved audibility. The Series ET appliances also incorporate a
Speaker Mounting Plate attached to the speaker for ease of installation. The Low Profile Speaker Strobes can provide a non-synchronized
strobe appliance when connected directly to a Fire Alarm Control Panel (FACP), or provide a synchronized strobe appliance when used in
conjunction with a Sync Module (SM), Dual Sync Module (DSM), or Power Booster (PS-12/24-8). The Strobes use a Xenon flashtube with
solid state circuitry enclosed in a rugged Lexan lens to provide maximum visibility and reliability for effective visible signaling. The
241575W candela wall mounted strobes are listed at 15 candela under UL Standard 1971 and meet 75 candela intensity on axis with low
current draw. The ET70 Speaker Strobes for wall mounting only are available with a choice of five UL Listed strobe options: 2415W,
241575W, 2430W, 2475W and 24110W. The ET90 Speaker Strobes for ceiling mounting only are available with a choice of four UL Listed
strobe options: 2415C, 2430C, 2475C, and 24100C. All models are Listed for indoor use only with the backboxes specified in these
instructions (see Mounting Options).
