Use this product according to this instruction manual. Please keep this instruction manual for future reference.
GENERAL:
Wheelock's Series NS Horn Strobe Appliances require only 2-wires for operation of the horn and strobe appliance and provide a
selectable continuous or Code 3 Horn tone and continuous strobe when connected directly to the Fire Alarm Control Panel (FACP).
They can also provide a synchronized Code 3 horn tone and synchronized strobe when used in conjunction with a Sync Module (SM),
Dual Sync Module (DSM) or Power Supply (PS-12/24-8). They are the ideal choice for applications where the audible silence feature
is required. The NS Appliances are UL Listed under Standard 1971 for Signaling Devices for the Hearing Impaired and UL Standard
464 for Audible Signal Appliances. They are listed for indoor use only and equipped with a NS Mounting Plate (NSMP) that can be
mounted to single-gang, double-gang, 4" backbox, 100mm European backbox or SHBB surface backbox (See Mounting Options).
These strobe models are Listed for wall mounting only. The NS Appliances use a Xenon flashtube with solid state circuitry enclosed
in a rugged Lexan lens to provide maximum visibility and reliability for effective visible signaling.
Series NS Appliances can be field set for High (HI) or Low (LO) dBA sound output.
These strobe models are designed for use with either filtered DC (VDC) or unfiltered Full-Wave-Rectified (FWR) input voltage. All
inputs are polarized for compatibility with standard reverse polarity supervision of circuit wiring by a FACP.
