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.

UL 1971 requires a polar light distribution pattern to enhance the likelihood of alerting
hearing impaired individuals throughout an area. Figure 2 illustrates the way the standard
measures light intensity, both horizontally and vertically. Tables 3 and 4 list the UL
minimum requirements and the actual value of the light intensity of the strobe signal.
