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

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.

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-WAVE­RECTIFIED (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.

Notes:

1. Set desired input voltage and dBA sound output level as follows (Refer to Figures 2 and 3).

2. 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.
