SERIES AMT MULTITONE STROBE APPLIANCE

GENERAL:

The AMT Multitone Strobe Appliance are UL Listed under Standard 1971 for Emergency Appliances for the Hearing Impaired and
UL Standard 464 for Audible Appliances. They are listed for indoor use only

with the backboxes specified in these instructions (See
Mounting Options). Models with LS and IS strobes are Listed for wall or ceiling mounting; models with LSM strobes are Listed for
wall mounting. The LSM strobes are listed at 15 candela under UL Standard 1971 and meet 75 candela intensity on axis with low
current draw. The AMT Multitone Strobe Appliance use a xenon flashtube with solid state circuitry enclosed in a rugged Lexan
lens to provide maximum visibility and reliability for effective visible signaling.

Wheelock's AMT Appliance are unique multitone alarm signals with separate input terminals for each sound. They are the ideal
choice for suppression systems and emergency signaling systems where distinctive multiple alarm conditions are required. Eight
groups of three self-prioritized sound outputs are provided with separate electrically isolated input terminals for each sound (see Table
2 and Table 8 for sound selections). Sound output can be field set to provide either HIGH (HI) dBA or STANDARD (STD) dBA
sound output level.

All AMT Multitone Strobe models are designed for use with either filtered or unfiltered Full-Wave-Rectified (FWR) input voltage.
The AMT Multitone Strobe Appliance have separate input terminals for alarm tone activation and strobe activation. The strobes can
be easily field programmed to operate independently or in unison with all of the audible alarms. All inputs are polarized for
compatibility with standard reverse polarity supervision of circuit wiring by a Fire Alarm Control Panel (FACP).

NOTE: All CAUTIONS and WARNINGS are identified by the symbol

WARNING: PLEASE READ THESE INSTRUCTIONS CAREFULLY BEFORE USING THIS PRODUCT. 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

WARNING: THESE APPLIANCES WERE TESTED TO
THE OPERATING VOLTAGE LIMITS OF 20-31 VOLTS FOR
24V MODELS AND 10.5-15.6 VOLTS FOR 12V MODELS
USING FILTERED (DC) OR UNFILTERED FULL-WAVE
RECTIFIED (FWR). DO NOT APPLY 80% AND 110% OF
THESE VOLTAGE VALUES FOR SYSTEM OPERATION.

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 signaling appliance.

WARNING: WHEELOCK STRONGLY RECOMMENDS THAT THE VOLTAGE APPLIED TO THESE PRODUCTS BE WITHIN
THEIR RATED VOLTAGE RANGE. THE APPLICATION OF IMPROPER VOLTAGE MAY RESULT IN DEGRADED OPERATION
OR DAMAGE TO THESE PRODUCTS, WHICH COULD RESULT IN PROPERTY DAMAGE AND SERIOUS INJURY OR DEATH TO
YOU AND/OR OTHERS.

Add 25% more input current than shown in Table 2 when operating the unit at maximum input voltage.

Add strobe current from Table 4 to audible signal current from Table 2 to obtain total current for each unit, if the strobe and audible
are wired to operate in unison on a single circuit.

Anechoic dBA is measured on-axis in a non-reflective (free
field) test room using fast meter response. For peak dBA
(measured with peak meter response), add 5 dBA to anechoic
values shown in Table 3. Reverberant dBA is a minimum UL
rating based on sound power measurements in a reverberant test
room.

WARNING: AMT MULTITONE STROBE MODELS SET
ON "SIREN AND VIBRATING CHIME TONES" WITH
STANDARD dBA DO NOT MEET THE 75 dBA MINIMUM UL
REVERBERANT SOUND LEVEL REQUIRED FOR PUBLIC
MODE FIRE PROTECTION SERVICE (NOTED BY * IN TABLE

3). MODELS WITH SETTINGS WHICH PRODUCE LESS
THAN 75 dBA MAY NOT BE HEARD. THIS SETTING IS
ACCEPTABLE ONLY FOR GENERAL SIGNALING (NON­FIRE ALARM) USE. USE THE "HIGH" dBA SETTING WITH
THIS TONE OR USE A DIFFERENT TONE FOR PUBLIC
MODE SERVICE.

WARNING: MAKE SURE THAT THE TOTAL AVERAGE CURRENT, TOTAL PEAK CURRENT AND TOTAL INRUSH
CURRENT REQUIRED BY ALL APPLIANCES THAT ARE CONNECTED TO THE SYSTEM'S PRIMARY AND SECONDARY
POWER SOURCES, SIGNALING CIRCUITS, SM, DSM SYNC MODULES AND PS-12/24-8 DO NOT EXCEED THE POWER
SOURCES' RATED CAPACITY OR THE CURRENT RATINGS OF ANY FUSES ON THE CIRCUITS TO WHICH THESE
APPPLIANCES 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.

When calculating the total average, peak and inrush currents: Use Table 4 to determine the highest value of "Rated Average Current"
for an individual strobe (across the expected operating voltage range of the strobe), determine the highest value of "Rated Inrush
Current" or "Tated Peak Current" (whichever is higher) of an individual strobe (across the expected 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 inrush current or peak current exceeds the power supplies' inrush 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 recove in some types of
power supplies. For example, an auxiliary opower 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.

CAUTION

WARNING: THE STROBES ARE DESIGNED TO FLASH AS SPECIFIED WITH CONTINUOUS (NON-CODED) APPLIED
VOLTAGE. THE STROBES MAY NOT FLASH IF USED IN CODED SYSTEMS.

: Strobes are not designed to be used on coded systems in which the applied voltage is cycled on and off.

All models are UL Listed for indoor use only with a temperature range of 32oF to 120oF (0oC to 49oC) and maximum humidity of
85% RH.

CAUTION

: If Multitone Strobe Appliances are operated within 15 inches of a person’s ear, they can produce a sound pressure
level that exceeds the maximum 120 dBA permitted by ADA and OSHA rules. Exposure to such sound levels can result in damage to
a person’s hearing.

NOTE: This equipment has been tested and found to comply with the limits for a Class B digital appliance, pursuant to Part 15 of the
FCC Rules. These limits are designed to provide reasonable protection against harmful interference in residential installation. This
equipment generates, uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions,
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 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) Connect the
equipment into an outlet on a circuit different from that to which the receiver is connected, and 4) Consult the dealer or an
experienced radio/TV technician for help.
