Use this product according to this instruction manual. Please keep this instruction manual for future reference.
GENERAL:
The Cooper Wheelock Series Z horn, strobe, and horn/strobe appliances are designed for easy installation. The ZNS horn/strobes and ZRS strobes are for 24V
operation and the ZNH horn is for 12V or 24V operation. The appliance comes in two main parts. The universal mounting back plate allows the appliance to be
mounted to a single-gang, double-gang, four square backbox, 4" octagon backbox, or a 3 ½" octagon backbox. Two wire appliance wiring is then connected to the
mounting back plate. This allows a continuity check of the entire NAC circuit before any appliances are attached. It also allows the appliances to be installed after all
finish work has been completed. The installer can snap or install the appliances when all other work is complete.

OF THE FOLLOWING INSTRUCTIONS, CAUTIONS AND WARNINGS COULD RESULT IN IMPROPER APPLICATION, CANDELA SETTING,

Strobe and Horn Strobe Appliances
Cooper Wheelock's Series Horn Appliances provide a selectable Continuous or Code 3 Horn tone when connected directly to the Fire Alarm Control Panel (FACP).
They can also provide a synchronized Code 3 Horn tone when used in conjunction with an FACP that incorporates the Wheelock sync protocol, a Wheelock Sync
Module, or the Wheelock Power Supply. The Horn Appliances can be field set for High (HI) or Low (LO) dBA sound output. The Horn Appliances are UL Listed
under Standard 464 for Audible Signal Appliances. They are listed for indoor use only. These models are designed for use with either filtered DC (VDC) or
unfiltered Full-Wave-Rectified (VRMS) input voltage. All inputs are polarized for compatibility with standard reverse polarity supervision of circuit wiring by a
FACP. The ZNS Horn/Strobe is for 24V operation only. The ZNH Horn is for 12V or 24V operation.
NOTE: The ZRS, ZNS, and ZNH are electrically identical to the corresponding RSS, NS, and NH models. Therefore, they carry the
existing UL compatibility listings.
NOTE: The Code 3 temporal pattern (1/2 second on, 1/2 second off, 1/2 second on, 1/2 second off, 1/2 second on, 1-1/2 off and repeat) is specified by ANSI and
NFPA 72 for standard emergency evacuation signaling. The Code 3 Horn should be used only for fire evacuation signaling and not for any other purpose.
