www.cooperwheelock.com E50 MULTI-CANDELA SPEAKER STROBES

GENERAL:

The E50 Multi-Candela Speaker Strobes are UL Listed under Standard 1971 for Signaling Devices for the Hearing Impaired and UL Standard 1480 for Speaker
Appliances. The E50A Multi-Candela Speaker Strobe with amber lens is not UL approved. 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 E50-24MCW provides four selectable candela settings (15,30,75, & 110cd), and the E50-24MCWH provides two selectable settings (135 &
185cd). All models are UL Listed for

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.

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.

6. Strobes with clear meet the required light distribution patterns defined in UL1971.

7. Candela ratings are for clear lens. Strobes with amber lens have 75% of the light output of clear lens.

NOTE: Candela setting will determine the current draw of the product.

NOTE: The maximum wire impendence 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.

LIGHT DISTRIBUTION:

NOTE: E50A with Amber lens is rated for 75% of the light output in Tables 3A & 3B.
