[phone] INSTALLATION INSTRUCTIONS
www.wheelockinc.com SERIES ET70/90 LOW PROFILE SPEAKERS AND SPEAKER STROBES

Use this product according to this instruction manual. Please keep this instruction manual for future reference.

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
241575W, 2430W, 2475W and 24110W. The ET90 Speaker Strobes for ceiling mounting only
strobe options: 2415C, 2430C, 2475C, and 24100C. All models are Listed for indoor use only

are available with a choice of five UL Listed strobe options: 2415W,

are available with a choice of four UL Listed

with the backboxes specified in these

instructions (see Mounting Options).

WARNING: MAKE SURE THAT THE TOTAL AVERAGE CURRENT, TOTAL PEAK CURRENT AND TOTAL
INRUSH CURRENT REQUIRED BY ALL APPLIANCES THAT ARE CONNECTED TO THE SYSTEM’S PRIMARY
AND SECONDARY POWER SOURCES, NAC CIRCUITS, SM AND DSM SYNC MODULES DO NOT EXCEED THE
POWER SOURCES’ RATED CAPACITY OR THE CURRENT RATINGS OF ANY FUSES ON THE CIRCUITS TO
WHICH THESE APPLIANCES ARE WIRED. OVERLOADING POWER SOURCES OR EXCEEDING FUSE RATINGS
COULD RESULT IN LOSS OF POWER AND FAILURE TO ALERT OCCUPANTS DURING AN EMERGENCY, WHICH
COULD RESULT IN PROPERTY DAMAGE AND SERIOUS INJURY OR DEATH TO YOU AND/OR OTHERS.

When calculating the total average, peak and inrush currents: Use Table 2 (for wall mount) and 2A (for ceiling mount) to determine
the highest value of “Rated Average Current” for an individual strobe (across the expected operating voltage range of the strobe), and
the highest value of “Rated Inrush Current” or “Rated Peak Current” (whichever is higher) of an individual strobe (across the
expected voltage range of the strobe), then multiply these values by the total number of strobes; be sure to add the currents for any
other appliances, including audible signaling appliances, powered by the same source and include any required safety factors.

If the inrush current or peak current exceeds the power supplies’ inrush capacity, the output voltage provided by the power supplies
may drop below the listed voltage range of the appliances connected to the supply and the voltage may not recover in some types of
power supplies. For example, an auxiliary power supply that lacks filtering at its output stage (either via lack of capacitance and/or
lack of battery backup across the output) may exhibit this characteristic.

CAUTION:

Strobes are not designed to be used on coded systems in which the applied voltage is cycled on and off.
