AMT MULTITONE APPLIANCES
AMT-12/24
Use this product according to this instruction manual. Please keep this instruction manual for future reference.
GENERAL:
AMT Multitone Appliances are UL Listed for Fire Protective Service, General Signaling Service and UL Standard 464 for Audible
Signal Appliances. They are listed for both indoor and outdoor use with the backboxes specified in these instructions. (See Mounting
Options A,B,C,D,E,F,G). Wheelock's AMT Appliances are unique multitone alarm appliances with separate input terminals for each
sound. They are the ideal choice for Halon Protection 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 4 for sound selections). Sound output can be field set to provide either HIGH (HI) dBA or
STANDARD (STD) dBA sound output level. AMT Multitone Appliances can be field set for either 12VDC or 24VDC operation and
are designed for use with either filtered or unfiltered (full-wave-rectified) input voltage. All inputs are polarized for compatibility
with standard reverse supervision of circuit wiring by Fire Alarm Control Panel (FACP).
NOTE: All CAUTIONS and WARNINGS are identified by the symbol . All warnings are printed in bold capital letters.
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 COULD RESULT IN PROPERTY DAMAGE AND SERIOUS INJURY OR DEATH TO YOU
AND/OR OTHERS.
WARNING: THE AMT MULTITONE APPLIANCES MUST BE FIELD SET TO THE DESIRED INPUT VOLTAGE,
dBA SOUND OUTPUT LEVEL AND ALARM TONE BEFORE THEY ARE INSTALLED. THIS IS DONE BY
PROPERLY INSERTING A JUMPER PLUG AND ADJUSTING A FOUR POSITION SWITCH IN ACCORDANCE WITH
THESE INSTRUCTIONS. INCORRECT SETTINGS WILL RESULT IN IMPROPER PERFORMANCE AND MAY
DAMAGE THE PRODUCT, WHICH COULD RESULT IN PROPERTY DAMAGE AND SERIOUS INJURY OR DEATH
TO YOU AND/OR OTHERS.

Maximum RMS Current
(AMPS)
WARNING: CHECK THE MINIMUM AND MAXIMUM OUTPUT OF THE POWER SUPPLY AND STANDBY
BATTERY AND SUBSTRACT THE VOLTAGE DROP FROM THE CIRCUIT WIRING RESISTANCE TO DETERMINE
THE APPLIED VOLTAGE TO THE SIGNALING APPLIANCE.
WARNING: FOR UL APPLIANCES THESE APPLIANCES WERE TESTED TO THE OPERATING VOLTAGE
LIMITS OF 16-33 VOLTS FOR 24V APPLICATIONS AND 8.0-17.5 VOLTS FOR 12V APPLICATIONS USING
FILTERED (DC) OR UNFILTERED FULL-WAVE-RECTIFIED (FWR). DO NOT APPLY 80% AND 110% OF THESE
VOLTAGE VALUES FOR SYSTEM OEPRATION.
WARNING: 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, OR
WHEELOCKS POWER SUPPLIES DO 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.
When calculating the total currents: Use Table 2 to determine the highest value of “RMS Current” for an individual AMT (across the
expected operating voltage range of the AMT’s), then multiply these values by the total number of AMT’s; be sure to add the currents
for any other 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.
The AMT Multitone audible appliances produce a brief inrush current that lasts for just 2 microseconds but can reach a peak value of
8.0 Amps (11.2 amps for FWR input).

AMT MULTITONE SETTINGS:
The Jumper Plug (DP1) and Switch (SW1) of the AMT Multitone Appliances, shown in Figure 1, are used to set the input voltage
dBA sound output level and alarm tone. The factory settings are shown below. Read these instructions carefully before changing
any of these factory settings.

STEP 1:
Set desired input voltage and dBA sound output level as follows (Refer to Figures 2 and 3):
AMT Multitone Appliances are field set for input voltage and dBA sound output level by inserting a Jumper Plug (DP1) and adjusting
a four position Switch (SW1) as shown in Table 3 and Figures 2 and 3. Use DP1 to select the desired voltage and SW1 Position 1 to
select the dBA sound output level.

WARNING: DO NOT APPLY 24VDC INPUT IF THE JUMPER PLUG (DP1) IS SET ON 12. THIS CAN DAMAGE
THE UNIT. DOUBLE CHECK THE JUMPER PLUG (DP1) AND SWITCH (SW1) SETTINGS TO MAKE SURE THEY
ARE CORRECT. IMPROPER SETTINGS CAN DAMAGE THE UNIT OR RESULT IN NO SOUND OUTPUT OR A dBA
SOUND OUTPUT LEVEL THAT IS BELOW THE MINIMUM CODE REQUIREMENTS FOR PUBLIC MODE FIRE
PROTECTION, WHICH COULD RESULT IN PROPERTY DAMAGE AND SERIOUS INJURY OR DEATH TO YOU
AND/OR OTHERS.
