www.wheelockinc.com
GENERAL:
The AMT Multitone Strobe Appliance is UL Listed under Standard 1971 for Emergency Appliances for the Hearing Impaired and UL Standard 464 for Audible
Appliances. The AMT is also ULC Listed under Standard CAN/ULC-S526-02 for Visual Signaling and under Standard CAN/ULC-S525-99 for Audible Signal
Devices for Fire Alarm Systems. The AMT Strobes can provide a non-synchronized strobe appliance when connected directly to a Fire Alarm Control Panel (FACP),
or provide a synchronized strobe appliance when used in conjunction with a Sync Module (SM), Dual Sync Module (DSM) or Wheelock power supplies. They are
listed for wall mount only,
candela under UL Standard 1971 and meet 75 candela intensity on axis with low current draw. The 24MCW model strobe can provide 4 selectable candela settings (15,
30, 75, 110). The AMT Multitone Strobe Appliances use a xenon flashtube with solid state circuitry enclosed in a polycarbonate lens to provide maximum visibility
and reliability for effective visible signaling.
Wheelock's AMT Appliances 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
Appliances 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 Canadian Installations should be in accordance with the Canadian Standard for the Installation of Fire Alarm Systems - CAN/ULC-S524-01 and Canadian
Electrical Code, Part 1. Final acceptance is subject to Authorities Having Jurisdiction.
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.

NOTE:
1. Strobes will produce 1 flash per second over the “Regulated Voltage” Range.
2. The strobe meets the required light distribution patterns defined in UL 1971 and ULC-S526-02.
3. All models are UL Listed for indoor use with a temperature range of +32°F to +120°F (0°C to +49°C) and maximum humidity of 93% ± 2% RH. The effect of
shipping and storage temperatures do not adversely affect the performance of the appliances when stored in the original cartons and are not subjected to misuse.
WARNING: THESE APPLIANCES WERE TESTED TO THE REGULATED VOLTAGE LIMITS OF 16.0-33.0 VOLTS FOR 24V MODELS USING
FILTERED DC OR UNFILTERED FULL-WAVE-RECTIFIED VOLTAGE. DO NOT APPLY VOLTAGE OUTSIDE OF THIS RANGE.
WARNING: 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 STROBES. THE MAXIMUM
WIRE IMPEDENCE BETWEEN STROBES SHALL NOT EXCEED 35 OHMS.
CAUTION: These notification appliances are UL Listed as “Regulated”. They are intended to be used with FACPs whose notification circuits are UL Listed as
“Regulated.” These appliances shall not be used on UL Listed “Special Application” notification circuits unless the appliances are identified to be compatible in the
installation instructions of the FACP or unless the FACP is identified to be compatible in this instruction manual.

Use Tables 3, 3A, 4, and 4A to determine the highest value of “Rated Current” for an individual AMT strobe (across the expected operating voltage range of the AMT
strobe). Add strobe current from Table 3 or 3A to audible appliance current from Table 2 and 2A to obtain total current for each unit, if the strobe and audible are wired
to operate in unison on a single circuit. 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.
NOTE: The maximum number of strobes on a single notification appliance circuit shall not exceed 50.

WARNING: THE AMT MULTITONE STROBE APPLIANCE MUST BE FIELD SET TO THE DESIRED dBA SOUND OUTPUT LEVEL AND
ALARM TONE BEFORE THEY ARE INSTALLED. THIS IS DONE BY PROPERLY 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.
AMT MULTITONE SETTINGS:
The Switch (SW1) of the AMT Multitone Strobe Appliances, shown in Figure 2, is used to set the desired alarm tone and dBA sound output level. The factory settings
are shown below. Read these instructions carefully before changing any of these factory settings.

Factory setting is on 15 Candela.
Move the candela selector to the desired setting.
The setting is indicated by the pointer and can be seen on the bottom side of the lens.
WARNING: THE CANDELA SELECT SWITCH MUST BE FIELD SET TO THE REQUIRED CANDELA INTENSITY BEFORE INSTALLATION.
WHEN CHANGING THE SETTING OF THE CANDELA SELECT SWITCH, MAKE CERTAIN THAT IT “CLICKS” IN PLACE. AFTER CHANGING
THE CANDELA SETTING, THE APPLIANCE MUST BE RETESTED TO VERIFY PROPER OPERATION. IMPROPER SETTING OF THE CANDELA
SELECT SWITCH MAY RESULT IN OPERATION AT THE WRONG CANDELA, WHICH COULD RESULT IN PROPERTY DAMAGE AND SERIOUS
INJURY OR DEATH TO YOU AND/OR OTHERS.
STEP 2:
Set desired dBA sound output level as follows (Refer to Figure 2):
AMT Multitone Appliances cannot be field set for input voltage. AMT Multitone Strobe Appliances are field set for dBA sound output level by adjusting a four
position Switch (SW1) as shown in Table 6 and Figure 2. Use SW1 Position 1 to select the dBA sound output level.
