Fire Alarm Systems | ZNS Series Ceiling‑mount Horn Strobes
ZNS Series Ceiling‑mount Horn Strobes
▶ Pre‑wire the base and test the circuit wiring before the
ceilings are covered
▶ Select continuous or temporal (Code 3) horn tones and
90 dBA or 95 dBA
▶ Select 24 V filtered DC (VDC) or unfiltered
Full‑Wave‑Rectified (Vrms) input voltage
▶ Select candela settings of 15/30/75/95 cd and
115/177 cd
The Cooper Wheelock ZNS Series Horn Strobes 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 and strobe when
used with an FACP that incorporates the Wheelock
synchronization protocol, a Wheelock Synchronization
Module, or the Wheelock Power Supply. The ZNS Horn
Strobes can be field set for high (HI) or low (LO) dBA sound
output. Strobes are designed to flash at 1 flash per second
minimum over their Regulated Voltage Range.
The ZNS Horn Strobes are designed for use with either 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.
The ZNS Series Horn Strobes, 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.
