-6dBA +/- 37 degrees horizontal; +/- 39 degrees vertical
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

CAUTION: The candela select switch must be field set to the required candela intensity before installation. When changing the setting of the
candela select switch make certain that it clicks in place. After changing the candela setting the appliance must be retested to verify proper
operation. Improper setting of the candela select switch may result in operation at the wrong candela.
MOUNTING OPTIONS
CAUTION: The following figures show the maximum number of field wires (conductors) that can enter the backbox used with each mounting option. If these
limits are exceeded, there may be insufficient space in the backbox to accommodate the field wires and stresses from the wires could damage the product.
Although the limits shown for each mounting option comply with the National Electrical Code (NEC), Cooper Wheelock recommends use of
the largest backbox option shown and the use of approved stranded field wires, whenever possible, to provide additional wiring room for easy
installation and minimum stress on the product from wiring.

MOUNTING PROCEDURES
CAUTION: Check that the installed product will have sufficient clearance and wiring room prior to installing backboxes and conduit, especially
if sheathed multiconductor cable or 3/4” conduit fittings are used.
E50H models have an integrated Speaker Mounting Plate.1.
The Speaker Mounting Plate must be oriented correctly when it is mounted to the backbox. Turn the Speaker Mounting Plate so that the2.
arrow above the words “Horizontal Strobe” points to the top side of the Speaker Mounting Plate.
First mount the Speaker Mounting Plate to the backbox. Next slide the grille over the Speaker Mounting Plate strobe until both snaps are3.
engaged.
When terminating field wires, do not use more lead length than required. Excess lead length could result in insufficient wiring space for4.
the signaling appliance.
Conduit entrances to the backbox should be selected to provide sufficient wiring clearance for the installed product.5.
Do not pass additional wires (used for other than the signaling appliance) through the backbox. Such additional wires could result in6.
insufficient wiring space for the signaling appliance.
Mounting hardware for each mounting option is supplied.7.
All models can be flush mounted to a 4” square by 2-1/8” deep backbox in the wall (Figure A).8.
Use care and proper techniques to position the field wires in the backbox so that they use minimum space and produce minimum stress9.
on the product. This is especially important for stiff, heavy gauge wires and wires with thick insulation or sheathing.
Use care to prevent speaker cone damage when driving screws for speaker product mounting.10.
WARNING: When installing strobes in an open office or other areas containing partitions or other viewing obstructions, special atten-
tion should be given to the location of the strobes so that their operating effect can be seen by all intended viewers, with the intesity,
number, and illumination, regardless of the viewer’s orientation.
The 110cd and 135/185cd settings are Listed for use in sleeping or non-sleeping areas when installed in accordance with appropriate NFPA
Standards and the Authority Having Jurisdiction.
WARNING: Installers must advise owners and operators of buildings with sleeping occupants, e.g., hotels and motels, to warn
guests, residents and employees to not move the bed location to a position violating points (1) and (2) above or serious injury and or
loss of life may occur during a fire emergency.
WARNING: A small possibility exists that the use of multiple strobes within a person’s field of view, under certain circumstances,
might induce a photo-sensitive response in persons with epilepsy. Strobe reflections in a glass or mirrored surface might also induce
such a response. To minimize this possible hazard, cooper wheelock strongly recommends that the strobes installed should not pres-
ent a composite flash rate in the field of view which exceeds five (5) hz at the operating voltage of the strobes. Cooper wheelock also
strongly recommends that the intensity and composite flash rate of installed strobes comply with levels established by applicable
laws, standards, regulations, codes and guidelines.
If this appliance is required to produce a distinctive three-pulse Temporal Pattern Fire Alarm Evacuation Signal (for total evacuation) in ac-
cordance with NFPA 72, the appliance must be used with a fire alarm control unit that can generate the temporal pattern signal. Refer to
manufacturer’s installation manual for details.
NOTE: NFPA 72/ANSI 117.1 conforms to ADAAG Equivalent Facilitation Guidelines in using fewer, higher intensity strobes within the same
protected area.
CAUTION: Check the installation instructions of the manufacturers of other equipment used in the system for any guidelines or restrictions on
wiring and/or locating Notification Appliance Circuits (NAC) and notification appliances. Some system communication circuits and/or audio
circuits, for example, may require special precautions to assure electrical noise immunity (e.g., audio crosstalk).
