INSTALLATION INSTRUCTIONS

SERIES NS TWO WIRE APPLIANCES

(WALL MOUNT VERSIONS)

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.

NOTE: All CAUTIONS and WARNINGS are identified by the symbol

. All warnings are printed in bold capital letters

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: 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. WARNING: THE AUDIBLE STROBE APPLIANCES MUST BE FIELD SET TO THE DESIRED TONE AND dBA SOUND OUTPUT LEVEL BEFORE THEY ARE INSTALLED. THIS IS DONE BY PROPERLY INSERTING JUMPER PLUGS IN ACCORDANCE WITH THESE INSTRUCTIONS.

WIRING INFORMATION: Figure 6. Figure 7. 1) NS Appliances have in-out wiring terminals that accepts two #12 to 18 American Wire Gauge (AWG) wires at each screw terminal. Strip leads 3/8” inches for connection to screw terminals. 2) Break all in-out wire runs on supervised circuit supervision as shown in Figure 7. The polarity shown in the wiring diagrams is for the operation of the appliances. The polarity is reversed by the FACP during supervision.
