www.wheelockinc.com E50-241575W SPEAKER STROBES

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

GENERAL:

Wheelock’s E50 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 2W, for either 25.0VRMS or 70.0VRMS audio systems. The 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 Speaker Strobes can provide non-synchronized
strobe operation when connected directly to a Fire Alarm Control Panel (FACP), or provide synchronized strobe operation when used
in conjunction with a Sync Module (SM), Dual Sync Module (DSM), or Wheelock’s Power Supplies, PS-12/24-8MP and PS-12/24­8CP. The E50-241575W wall mounted strobes are listed at 15 candela under UL Standard 1971 and meet 75 candela intensity on axis
with low current draw. All models are UL Listed for indoor use only
instructions (see Mounting Options).

NOTE: All CAUTIONS and WARNINGS are identified by the symbol . All warnings are printed in bold capital letters.

CAUTION: The speaker strobe appliance is a fire alarm device - do not paint.

WARNING: PLEASE READ THESE INSTRUCTIONS CAREFULLY. FAILURE TO COMPLY WITH ANY OF THE
FOLLOWING INSTRUCTIONS, CAUTIONS AND WARNINGS COULD RESULT IN IMPROPER APPLICATION,
INSTALLATION AND/OR OPERATION OF THESE PRODUCTS IN AN EMERGENCY SITUATION, WHICH COULD
RESULT IN PROPERTY DAMAGE AND SERIOUS INJURY OR DEATH TO YOU AND/OR OTHERS.

* 1575W models are UL Listed at 15cd and meet 75cd on axis.

NOTES:

1. Strobes will produce 1 flash per second over the “Regulated Voltage” range.

2. All models are UL Listed for indoor use with a temperature range of +32ºF to +120ºF (0ºC to +49ºC) and maximum

humidity of 85% RH.

3. dBA is rated per UL Standard 1480 for Speaker Appliances. Frequency range of speakers is 400-4000Hz.

4. For UL applications these appliances were tested to the operating voltage limits of 16-33 volts using filtered (DC) or

unfiltered full-wave-rectified (FWR). Do not apply 80% and 110% of these voltage values for system operation.

5. Check the minimum and maximum output of the power supply and standby battery and subtract the voltage drop from the

circuit wiring resistance to determine the applied voltage to the strobes.

Table 2: UL Current Rating for Strobe Only

Maximum RMS Current (AMPS)

UL Voltage 15/75cd
DC 16-33VDC 0.090
FWR 16-33VRMS 0.145

NOTE: The maximum wire impedence between strobes shall not exceed 35 OHMS. The maximum number of strobes on a single
notification appliance circuit shall not exceed 47.

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

NOTE: Make sure that the total RMS current required by all appliances that are connected to the system’s primary and secondary
power sources, NAC circuits, SM, DSM SYNC modules or Wheelock Power Supplies do not exceed the power sources’ rated
capacity or the current ratings of any fuses on the circuits to which these appliances are wired.

WARNING: OVERLOADING POWER SOURCES OR EXCEEDING FUSE RATINGS COULD RESULT IN LOSS OF

POWER AND FAILURE TO ALERT OCCUPANTS DURING AN EMERGENCY.

When calculating the total currents, use Table 2 to determine the highest value of “RMS Current” for an individual strobe (across the
expected operating 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 peak current exceeds the power supplies’ peak 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.
