Notification Appliances—E Series Speakers and Strobe Speakers 3
Introduction
The E series speakers and strobe speakers are UL Listed under Standard 1971 for
signaling devices for the hearing impaired and UL Standard 1480 for speaker appliances.
These speakers and strobe speakers are manufactured by Wheelock for use with Johnson
Controls systems. All models offer a choice of field selectable taps for
1/4, 1/2, 1, or 2 watt speaker operation. All inputs are compatible with standard reverse
polarity supervision of circuit wiring by a Fire Alarm Control Panel (FACP).
The E series design incorporates a high efficiency speaker for maximum output at
minimum power across a frequency range of 400 to 4000 Hz, and features a sealed back
construction for extra protection and improved audibility. The optional strobe for the E
series speakers incorporates a xenon flashtube with solid-state circuitry enclosed in a
rugged LEXAN®lens to provide maximum reliability for effective visible signaling. The
strobe speakers are available with a choice of four UL Listed strobe options: series LS,
LSM, MS, and IS. (Refer to the LS, LSM, MS, and IS Series Strobe Signals Technical
Bulletin for specific information regarding these strobe signals.) All models are UL
Listed for indoor use. The LS, MS, and IS models are listed for ceiling or wall mount.
The LSM models are listed for wall mount only, using the backboxes specified in this
document. (See the Mounting section of this document.)

General
Description

4 Notification Appliances—E Series Speakers and Strobe Speakers
Johnson Controls is not responsible for devices that have been improperly installed,
tested, or maintained by others. All models are UL Listed for indoor use with a
temperature range of 32 to 120°F (0 to 49°C) with a maximum relative humidity of 85%.
The speakers and strobe speakers operate on Full-Wave Rectified (FWR), unregulated
(unfiltered) DC voltage as well as regulated (filtered) DC. Performance ratings are based
on nominal input voltages 24 VDC
(20 VDC to 31 VDC).
The frequency range of the speakers is 400 to 4000 Hz. Operate only within the specified
voltage range for rated performance and endurance.
All strobe models are designed to flash as specified with continuous nominal applied
voltage. The flash rate for the strobe is approximately one flash per second at nominal
voltage. Strobes are not designed to be used on coded systems in which the applied
voltage is cycled on and off.
All candela (cd) ratings represent effective intensity based on UL 1971.
This equipment has been tested and complies with the limits for a Class B digital device,
pursuant to Part 15 of the FCC rules. These limits are designed to provide reasonable
protection against harmful interference in installations. This equipment generates, uses,
and radiates radio frequency energy. If not installed and used in accordance with the
instructions, this equipment may cause harmful interference to radio communications.
However, there is no guarantee that interference will not occur in a particular installation.
If this equipment does cause harmful interference to radio or television reception, which
can be determined by turning the strobe and/or audible equipment off and on, the user is
encouraged to try to correct the interference by one or more of the following measures:
1. Reorient or relocate the receiving antenna.
2. Increase the separation between the equipment and receiver.
3. Consult the dealer or an experienced radio/TV technician for help.

!
CAUTION: Equipment damage hazard. Although UL testing has
verified these products function at 80% of their minimum
rating and 110% of their maximum rating, Johnson Controls
recommends that the voltage applied to these products be
within their rated input voltage range. The application of
improper voltage may result in degraded operation or damage
to these products.
To verify that the signaling device is operating at rated voltages, determine the voltage
drop caused by the resistance of the Notification Appliance Circuit (NAC) wiring. Then,
subtract this voltage from both the maximum and minimum power supply and battery
voltages.

* All VFWR voltages are measured with a DC voltmeter. Multiply VFWR voltage by 1.11 to convert
values to VRMS.
Verify electrical ratings specified in Tables 1 and 2 to ensure proper electrical input.
Verify speaker wires are only connected to speaker terminals and strobe wires are only
connected to strobe terminals. Verify wiring at the panel, power supply, and/or NAC
control point is correct.
To calculate the total strobe current:
1. Use Table 2 to determine the highest value of rated average current for an individual
strobe.
2. Add this value to the total values of the strobes on the circuit.
3. Add the current for any other devices powered by the same source, including any
required safety factors.
Note: Calculate the total audible signal current in the same manner based on the input
voltage and the selected wattage of each individual speaker.
!
CAUTION: Equipment damage hazard. Improper electrical input may
damage the device or cause it to malfunction.

Installation Procedures
!
WARNING: Personal injury hazard. Under certain circumstances, the
use of multiple strobes within a person’s field of view, and
strobe reflections in a glass or mirrored surface might induce
a photosensitive response in persons with epilepsy.
To minimize this possible hazard, Johnson Controls strongly recommends that the number
of strobes installed within a single room, hallway, or other field of vision not exceed the
parameters prescribed by the
NFPA-72-National Fire Alarm Code and UL standards.
Johnson Controls strongly recommends the intensity and flash rates of such strobes not
exceed those levels established by applicable laws, standards, regulations, and guidelines.
The number of installed strobes should not present a composite flash rate in the field of
view which exceeds five hertz at the operating voltage of the strobes.
Note: NFPA 72 and ANSI 117.1 Standards provide means for determining equivalent
illumination using fewer, higher intensity strobes within the same protected area.
Installation of strobe products in sleeping areas should be wall mounted as follows:
1. The on-axis (directly in front of lens) light output should be directed at the eyelids of
the sleeping person, such as the pillow end of bed, or the bed head.
2. No part of the bed shall be more than 16 feet from the strobe notification appliance.
!
WARNING: Personal injury hazard. Installers must advise owners and
operators of buildings with sleeping occupants to warn
guests, residents, and employees not to 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.
!
WARNINGS: Personal injury hazard. When installing strobes in an open
office or other area containing partitions or other viewing
obstructions, ensure the strobes operating effect can be seen
by all intended viewers. The intensity, number, and type of
strobes must alert the viewer, regardless of the viewer’s
orientation.
!
WARNINGS: Personal injury hazard. NFPA-72-National Fire Alarm
Code requires supervision of notification appliance circuits.
Check if unsupervised circuits violate any applicable codes.

CAUTION: Equipment Hazard. Do not use in potentially explosive
atmospheres. Do not leave unused wires exposed.

Notification Appliances—E Series Speakers and Strobe Speakers 13
Refer to Figures 2 through 4 when installing units. Use mounting
Option B for E-9025 and E-9070 models. Use mounting Option A or C for E-7025 and
E-7070 models. Order plates and backboxes separately. Special plates and backboxes
are indicated in the illustrations and described in Table 9, located in the Mounting
Accessories section
Mounting hardware is included for each mounting option. You can fill the two unused
mounting holes using the short screws and retaining nuts (provided in the hardware bag)
prior to mounting the device to the backbox.
Note: The models are illustrated with the optional strobe.
!
CAUTION: Equipment damage hazard. The National Electrical Code
(NEC) Article 370-6 limits the maximum number of
conductors that can enter a backbox based on the size of the
backbox and the size of the wiring used. Johnson Controls
recommends that you adhere to the conductor limitations
shown in the tables following each mounting option.
Johnson Controls also recommends that you use a 2-1/8 inch deep extension ring added to
the 4 inch square backbox where possible to provide additional wiring room for easy
installation.
!
CAUTION: Equipment damage hazard. The mounting methods
described in this document are only applicable within the
continental United States. Extension rings provided outside
of the United States may not meet the required specifications
for successful mounting purposes and may damage your
speakers. Consult Wheelock, Inc. for appropriate mounting
instructions in countries other than the United States.
General mounting instructions:
1. Select the largest backbox possible to provide additional wiring room for easy
installation (Figures 3 through 5).
2. Select the conduit entrance to backboxes to ensure sufficient wiring clearance for
installed equipment. When extension rings are required, enter the conduit through
the backbox, not the extension ring. Use Steel City No. 53151 x 1-1/2 inch deep or
No. 53171 x 2-1/8 inch deep extension rings or the equivalent with same area cut
out in back.
Note: If a sheathed multiconductor cable or 3/4 inch conduit fitting is used, check that
the installed product has sufficient clearance and wiring room prior to installing
the backboxes and conduit.
!
CAUTION: Equipment damage hazard. Check the installation
instructions of the manufacturers of other equipment used in
the system for any guidelines or restrictions on wiring and/or
locating signaling circuits and signaling devices.

Use care and proper techniques when positioning the field wires in the backbox. Be sure
to use the minimum required space and avoid undue stress on the product. This is
especially important for stiff, heavy gauge wires and wires with thick insulation or
sheathing.
Do not use more lead length than required when terminating field wires. Excess lead
length may result in insufficient wiring space for the signaling device. Do not pass
additional wires (used for equipment other than the signaling device) through the
backbox. Excessive wires may result in insufficient wiring space for the signaling device.
Refer to Figures 6 and 7 when wiring the device. Figure 6 illustrates the polarity for the
proper operation of the strobe notification appliance. Reverse the polarity for DC
supervision of the NAC.

Notification Appliances—E Series Speakers and Strobe Speakers 19
The peak inrush current waveforms for the strobe of the E series strobe speakers are
shown below (Figure 9). Circuit fuses, control devices for the NAC, and power supplies
must be rated to handle this inrush. Current limitations will not prevent the startup unless
the power supply current limiting is achieved by a fast reacting voltage fold-back circuit.
Therefore, if the power supply does not have a fast reacting voltage fold-back circuit, the
power supply ratings can be based on the rated (steady state) current draw (Figure 9).
Make sure the system power supply is compatible with the specified inrush current.
!
WARNING: Personal injury hazard. Ensure all fuses used on NACs are
rated to handle the maximum inrush or peak current from all
devices on the circuit. Failure to do this may result in loss of
power to the NAC and the failure of all devices on that circuit
to operate.
Note: Inrush current refers to current that exceeds the nominal voltage when the strobe
is first turned on. Once the strobe is turned on, it flashes one flash per second.
Peak current indicates the current rising above the nominal voltage right after
each strobe flash.
To calculate the maximum inrush or peak current:
1. Use Table 2 to determine the highest value of rated inrush current or rated peak
current (whichever is higher) for an individual strobe.
2. Measure across the expected operating voltage range of the strobe.
3. Multiply this value by the total number of strobes on the circuit.
4. Add the inrush or peak currents from any other devices on the circuit and include
any required safety factors.

Test your alarm system per the applicable codes and standards specific to the location and
use of your facility.
The audible device and/or strobe will not work without power. The audible device/strobe
gets its power from the fire/security panel monitoring the alarm system. If power is cut
off for any reason, the audible device/strobe will not provide the desired audio or visual
warning.
The audible device may not be heard. The loudness of the audible device meets or
exceeds current Underwriters Laboratories standards. However, the audible device may
not alert a sound sleeper, one who has recently used drugs, or one who has been drinking
alcoholic beverages. The audible device may not be heard if it is placed on a different
floor from the person in hazard, or if it is placed too far away to be heard over ambient
noise such as traffic, air conditioners, machinery, or music appliances that may prevent
alert persons from hearing the alarm. The audible device may not be heard by persons
who are hearing impaired.
The signal strobe may not be seen. The electronic visual warning signal that flashes at
least once every three seconds meets or exceeds current Underwriters Laboratories
Standard 1971, and uses an extremely reliable xenon flash tube. The visual warning
signal is suitable for direct viewing and must be installed within an area where it can be
seen by building occupants. The strobe must not be installed in direct sunlight or in areas
of high light intensity (over 60 foot candles) where the visual flash might be disregarded
or not seen. The strobe may not be seen by the visually impaired.
The signal strobe may cause seizures. Individuals who have a positive photic response to
visual stimuli with seizures, such as epileptics, should avoid prolonged exposure to
environments in which strobe signals, including this strobe, are activated.
Johnson Controls recommends that the sounder and signal strobe be used in combination
to minimize risk.
The signal strobe cannot operate from coded power supplies. Coded power supplies
produce interrupted power. The strobe must have an uninterrupted source of DC power
in order to operate correctly.
