ZNH Horns
www.boschsecurity.com
The Cooper Wheelock ZNH Horns provide a selectable
continuous or Code 3 horn tone when connected
directly to the Fire Alarm Control Panel (FACP). They
also provide a synchronized Code 3 horn tone when
used with an FACP that incorporates the Wheelock
synchronization protocol, a Wheelock Synchronization
Module, or the Wheelock Power Supply. They can be
field set for high (HI) or low (LO) dBA sound output.
These horns are designed for use with either 12 V or
24 V 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 an FACP.
These horns, like all Cooper Wheelock Z Series
appliances, are designed for easy installation. The
universal two-wire base allows a continuity check of
the entire NAC circuit before any appliances are
attached and allows the appliances to be installed
after all finish work has been completed. The
appliances simply snap onto the universal bases.

The D7022 can be set for either 12 V or 24 V
operation. The ZNH Horns automatically adjust for
either voltage.

When used with a D7039 Multiplex Expansion
Module, the D7024 becomes an addressable fire alarm
control panel (FACP). The ZNH Horns automatically
adjust for 24 V operation.

For synchronization, use the SM or DSM modules
with these control panels and set the synchronization
module for 24 VDC operation.
