Use this product according to this instruction manual. Please keep this instruction manual for future reference.
GENERAL
The Wheelock E50H Series High-Fidelity Multi-Candela Speaker Strobes are UL Listed under Standard 1971 for Signaling Devices for the Hear-
ing Impaired, UL Standard 1480 for Speaker Appliances and ULC Listed under Standard CAN/ULC-S541-07 and CAN/ULC-S526-07 for indoor
Fire Protective Service. They are designed for multiple power requirements with high dBA output at each power tap. Series E50H, High Fidelity
Speakers, are UL Listed under UL Standard 1480 and ULC Listed under Standard CAN/ULC-S541-07 for Speaker Appliances. All models offer
a choice of field selectable taps, 1/8W to 2W, for either 25.0 V
RMS
or 70.0 V
RMS
audio systems. The design incorporates a high efficiency speaker
for maximum output at minimum power across a frequency range of 300-8000Hz. 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 Dual Sync Module (DSM), or Wheelock’s Power Supplies. All models are Listed for
indoor use only
with the backboxes specified in these
instructions (see Mounting Options).
1/8W tap setting for Private Mode only. E50H-241575W is UL Listed only.
NOTE:
All Canadian Installations should be in accordance with the Canadian Standard for the Installation of Fire Alarm Systems – CAN/ULC-
S524-01 and Canadian Electrical Code, Part 1. Final acceptance is subject to Authorities Having Jurisdiction.
WARNING
: This 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
Strobes will produce 1 flash per second over the “Regulated Voltage” range.
Ř
All models are Listed for indoor use with a temperature range of +32ºF to +120ºF (0ºC to +49ºC) and maximum humidity of 95% RH. The
Ř
effect of shipping and storage temperatures shall not adversely affect the performance of the appliance when it is stored in the original
cartons and is not subjected to misuse or abuse.
dBA is rated per UL Standard 1480 and ULC Standard ULC-S541-07 for Speaker Appliances. Frequency range of speakers is 300-8000Hz.
Ř
These appliances were tested to the operating voltage limits of 16-33 volts using Filtered (DC) or unfiltered Full-Wave-Rectified (FWR). Do
Ř
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 circuit wiring
Ř
resistance to determine the applied voltage to the strobes.

NOTE:
The maximum wire impedance 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 DSM Sync Modules or Wheelock Power Supplies do not exceed the power sources’ rated capacity or the current rat-
ings 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.
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.
E50H Speaker Strobe models have in-out wiring terminals that accept two #12 to #18 American Wire Gauge (AWG) wires at each screw
1.
terminal. Strip leads 3/8 inches and connect to screw terminals.
Break all in-out wire runs on supervised circuits to assure integrity of circuit supervision as shown in Figure 2. The polarity shown in the
2.
wiring diagrams is for operation of the appliances.
Refer to Sync Module instruction sheets SM (P83123), DSM (P83177) or Wheelock Power Supplies for additional information.

GROUNDING:
Connect ground wire to backbox. Install signaling appliance to backbox using mounting screws provided.
NOTE:
Check electrical ratings specified in tables 1 and 2 (as appropriate) to ensure proper electrical input. Ensure the speaker wiring is con-
nected to speaker terminals only, and strobe wiring is connected to strobe terminals only. Ensure the wiring at the FACP is correct.
NOTE:
Wiring method shall be in accordance with CSA C22.1, Canadian Electrical Code, Part 1, Safety Standard for Electrical Installations,
Section 32.
WARNING: Improper electrical input can damage the product or cause it to malfunction.
