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-12/24-
8CP. 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 and wall mounting only with the backboxes specified in these
instructions (see Mounting Options).
NOTE: All CAUTIONS and WARNINGS are identified by the symbol
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.

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.
For UL applications these appliances were tested to the operating voltage limits of 16-33 volts using filtered (DC) or
4.
unfiltered full-wave-rectified (FWR). Do not apply 80% and 110% of these voltage values for system operation.
Check the minimum and maximum output of the power supply and standby battery and subtract the voltage drop from the
5.
circuit wiring resistance to determine the applied voltage to the strobes.
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.
Speaker Strobes are not designed to be used on coded systems in which the applied voltage is cycled on and off.

- Page 2 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.
- Page 3 WIRING INFORMATION: A 1.5µF blocking capacitor for DC supervision of audio lines by the FACP is factory wired in series with the speaker input. Supervision voltage must not exceed 33 volts DC. Figure 1: Figure 2: 1. Low Profile E50 Speaker Strobe models have FROM PRECEDING SPEAKER TO NEXT SPEAKER in-out wiring terminals that accept two #12 to...
