for Speaker Appliances and ULC Listed under Standard CAN/ULC-S541-07 and CAN/ULC-S526-07 for indoor Fire Protective Service. Speaker strobes with amber, blue, green
and red lens are UL Listed under Standard 1638 (Visual Signaling Appliance) for Private Mode Emergency and General Utility Signaling. 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 opera-
tion 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. E50H series speakers are UL rated to meet the NFPA 72 requirement for 520Hz signals in sleeping areas when used
in conjunction with Wheelock Safepath products (see SP40S manual for more details)
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 Electri-
cal 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
:
• 1575W models are UL Listed at 15cd and meet 75cd on axis
• Strobes will produce 1 flash per second over the “Regulated Voltage” range.
• 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 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.
• 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.
• 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.
• Strobes with clear and amber lens meet the required light distribution defined in UL1971.
• Candela ratings are for clear lens. Derate approximately 25% for amber lens, 55% for green, 75% for blue and 80% for red. Model numbers will have a letter after the
H to designate lens color (A, G, B or R).

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 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 appli-
ances 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.
1. E50H Speaker Strobe models have in-out wiring terminals that accept two #12 to #18 American Wire Gauge (AWG) wires at each screw terminal. Strip leads 3/8 inches
and connect to screw terminals.
2. 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 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 connected 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.
