DC 16-33VDC 0.090
FWR 16-33V
RMS
0.145
When calculating the total currents use Table 2 to determine the highest value of RMS current for an individual 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 to include any required safety factors.
NOTE: The maximum number of strobes on a single notification appliance circuit shall not exceed 50.
CAUTION: These strobes are UL Listed as “Regulated”. They are intended to be used with FACPs whose notification circuits are UL
Listed as “Regulated.” These appliances shall not be used on UL Listed “Special Application” notification circuits unless the appliances
are identified to be compatible in the installation instructions of the FACP or unless the FACP is identified to be compatible in this instruction manual.
WARNING: These strobes were tested to the regulated voltage limits of 16.0-33.0 Volts for 24V models using filtered DC or unfiltered full-wave-rectified voltage. Do not apply voltage outside of this range.
WARNING: 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. The maximum wire impedance between strobes shall
not exceed 35 ohms.
CAUTION: Strobes are not designed to be used on coded systems in which the applied voltage is cycled on and off.
WARNING: Make sure that the total RMS current required by all appliances that are connected to the system’s primary and
secondary power sources, notification appliance circuits, SM, DSM sync modules, or Cooper Wheelock power supplies does
not exceed the power sources’ rated capacity or the current ratings of any fuses on the circuits to which these appliances are
wired. Overloading power sources or exceeding fuse ratings could result in loss of power and failure to alert occupants during an
emergency, which could result in property damage and serious injury or death to you and/or others.
WIRING AND MOUNTING INFORMATION
CAUTION: The following figures (A-D) 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. Check that the installed product will have sufficient clearance and wiring room prior to installing
backboxes and conduit, especially if sheathed multi-conductor cable or 3/4” conduit fittings are used.
Although the limits shown for each mounting option comply with the National Electrical Code (NEC), Cooper Notification 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.
NOTE: Surface backbox (SBB) in Figures C & D, is compatible with wiremold and conduit, mounting holes are for single-gang, doublegang, 4”sq., 3-1/2” & 4” octagon or round backboxes.

MOUNTING PROCEDURES
1. These models can be flush mounted to a 4” square by 2-1/8” deep backbox with a 4” square 1-1/2” extension ring (Figure A) or
surface mounted to a surface backbox (Figure B). Mounting hardware for each mounting option is supplied.
2. Conduit entrances to the backbox should be selected to provide sufficient wiring clearance for the installed product. Do not pass
additional wires (used for other than the signaling appliance) through the backbox. Such additional wires could result in insufficient
wiring space for the signaling appliance.
3. When terminating field wires, do not use more lead length than required. Excess lead length could result in insufficient wiring space
for the signaling appliance.
4. Use care and proper techniques to position the field wires in the backbox so that they use minimum space and produce minimum
stress on the product. This is especially important for stiff, heavy gauge wires and wires with thick insulation or sheathing.
5. These models have an integrated speaker mounting plate which must be oriented correctly when it is mounted to the backbox. Turn
the speaker mounting plate so that the arrow above the words “Horizontal Strobe” points to the top side of the speaker mounting
plate.
6. Mount the speaker mounting plate to the backbox. Next slide the grille over the speaker mounting plate strobe and attach with (2)
screws.
WARNING: The E70/90 speaker strobe appliance is a “Fire Alarm Device - Do Not Paint.”
WARNING: When installing strobes in an open office or other areas containing partitions or other viewing obstructions, special
attention should be given to the location of the strobes so that their operating effect can be seen by all intended viewers, with
the intensity, number, and type of strobes being sufficient to make sure that the intended viewer is alerted by proper illumination,
regardless of the viewer’s orientation. Failure to do so could result in property damage and serious injury or death to you and/or
others.
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 Notification strongly recommends that the strobes installed
should not present a composite flash rate in the field of view which exceeds five (5) hz at the operating voltage of the strobes.
Cooper Notification 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
accordance 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).
