Cautions
ELECTRICAL HAZARD: Disconnect power from equipment
prior to making any internal adjustments. Service should
only be performed by qualified personnel.
FRAGILE: Inspect the equipment prior to installation. Do not
install the equipment if damage is apparent. Do not attempt
to disassemble this equipment. If damaged, return to the
supplier.
ELECTROSTATIC HAZARD: This is sensitive electronic
equipment. Apply safe ant-static practices when handling
this equipment.
CIRCUIT LIMITATIONS: The maximum number of detectors
connected to a single detection zone is limited by the control
and indicating equipment, and may be limited by local
regulations.
General Description
The Multi-tone Horn appliance is an indoor use only and DC
24V powered, two-line non-addressable multi-audible alarm
appliance.
The product can be separated from the controller or
synchronize functional module (SFM) to work independently,
when multiple appliances are connected to a same UL listed
control panel or synchronization module, the sound
synchronization between products in the same
loop circuit area can be realized.
Caution: The appliances emit sound alarm means there
may be an emergency, and it should be attention
immediately.

VL-W-M Non Addressable Multi-tone NAC
The Minimum sound pressure is measured in UL reverberant
test
chamber.
Adjust the Dip-switch in the back of the product to change the
alarm horn mode. See Figure 1.
Wiring
Make sure the total current consumption of the circuit
does not exceed the maximum load current of the
FACP or SFM module, the device quantity must be
considered in the design of the loop system.
Number of circuit is connected with the maximum number
of notification products must calculate the loop line loss of
voltage to ensure loop notification products work in rated
voltage range, please refer to the corresponding FACP or
NAC SFM and other equipment installation instructions.
