SERIES AMT MULTITONE STROBE APPLIANCES
INSTALLATION INSTRUCTIONS
Use this product according to this instruction manual. Please keep this instruction manual for future reference.
GENERAL:
AMT-241575W-NYC
The AMT Multitone Strobe Appliance is UL Listed under Standard 1971 for Signaling Appliances for the Hearing Impaired and UL
Standard 464 for Audible Signal Appliances. 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’s Power Supplies. The AMT-241575W is listed for wall mounting and indoor
use only
with the backboxes specified in these instructions (See Mounting Options). The 1575 candela wall mounted strobe is listed
at 15 candela under UL Standard 1971 and meet 75 candela intensity on axis with low current draw. The AMT Multitone Strobe
Appliance uses a Xenon flashtube with solid state circuitry enclosed in a rugged Lexan lens to provide maximum visibility and
reliability for effective visible signaling.

NOTE
Wheelock's AMT Appliance is a unique multitone alarm appliances with separate input terminals for each sound. It is the ideal
choice for suppression systems and emergency signaling systems where distinctive multiple alarm conditions are required. Sound
output can be field set to provide either HIGH (HI) dBA or STANDARD (STD) dBA sound output level.
The AMT Multitone Strobe model is designed for use with either filtered or unfiltered Full-Wave-Rectified (FWR) input voltage.
The AMT has separate input terminals for alarm tone activation and strobe activation. The strobe can be easily field programmed to
operate independently or in unison with all of the audible appliances. All inputs are polarized for compatibility with standard reverse
polarity supervision of circuit wiring by a Fire Alarm Control Panel (FACP).
The Series AMT is a single multitone device capable of three separate and distinct signals from three different sources together with
an ADA compliant strobe light. These devices may be employed only in the following installations:
1. Computer rooms, libraries, museums, etc. which utilize FM-200, halon inergen or any other fire extinguishing system as defined
in the Rules of the City of New York 15-08.
2. Pre-Action Sprinkler Systems
3. In lieu of the three separate and distinct signals at the Interior Fire Alarm, Smoke Detection and Sprinkler Alarm Systems control
panel.
Table 1 below shows the following sequence of tones for various systems.

For example, whenever the vibrating chime (Priority 3) is activated in a computer room protected by FM-200 agent, then the
occupants will know that one smoke detector has been activated. When the code 3 horn (Priority 2) is activated, then the occupants
will be advised to evacuate the premises and finally the bell tone (Priority 1) means the release of the extinguishing agent. The ADA
compliant strobe will be activated upon the first fire detection and will stay on throughout the sequence of operation leading to
discharge.
Please note that during any time when multiple signals are received a Priority 3 signal shall be overridden by a Priority 2 signal which
consequently shall be overridden by a Priority 1 signal.
Suitably engraved signage explaining the significance of each signal will be placed near each of the signaling devices.

The AMT Multitone Audible appliances produce a brief inrush current that lasts for 2 microseconds but it can reach a peak value of
8.0 Amps (11.2 Amps for FWR input).
* The time duration for the peak/inrush current is 10 milliseconds.
P84157 C
Sheet 2 of 8
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 AND NAC CIRCUITS, SM, DSM SYNC MODULES AND WHEELOCK’S 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 average, peak or inrush currents: Use Table 3A and 3B to determine the highest value of “Rated Average
Current” for an individual strobe (across the expected operating voltage range of the strobe), to determine the highest value of “Rated
Inrush Current” or “Rated 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 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.
CAUTION
: Strobes are not designed to be used on coded systems in which the applied voltage is cycled on and off.
