Series ZNS
Description:
The Wheelock Series Z notification appliances feature an easy snap
on base that is designed to simplify the installation and testing of
horns, strobes, and horn/strobes. The separate Series Z snap on
base can be pre-wired so circuit wiring can be fully tested before
the appliance is installed and before the walls are covered. Once
all surrounding work is complete, the appliance can be simply
installed by snaping it on the base. Shorting contacts in the base,
which provide continuity for circuit testing, are permanently opened
when the appliance is installed so any subsequent removal of the
appliance will indicate a trouble condition on that circuit at the control
panel when circuit supervision is enabled. The same base is used
for all Series Z horns, strobes and horn/strobes to provide consistent
installation and easy replacement of appliances if required. A locking
screw is also included for the appliance to provide extra secure
installation.
The Wheelock Series Z appliances incorporate the same dependable
circuitry and high efficiency optics that are used in Wheelock RSS
strobes, NS horn/strobes and NH horns and have the same high
performance ratings. The Series Z appliances are compatible with
all UL listed “Regulated” panels and all panels that are compatibility
listed with Wheelock RSS, NS and NH appliances.

General Notes:
• Strobes are designed to flash at 1 flash per second minimum over their “Regulated Voltage Range”.
• All candela ratings represent minimum effective strobe intensity based on UL Standard 1971.
• Series ZNS Strobe products are listed under UL Standards 1971 and 464 for indoor use with a temperature range of 32°F to 120°F (0°C to
49°C) and maximum humidity of 93% (± 2%).
• Series ZNH horns are listed under UL Standard 464 for audible signal appliances (Indoor use only).
• “Regulated Voltage Range” is the newest terminology used by UL to identify the voltage range. Prior to this change UL used the terminology
“Listed Voltage Range”.

* UL max current rating is the maximum RMS current within the listed voltage range (16-33v for 24v units). For strobes
the UL max current is usually at the minimum listed voltage (16v for 24v units). For audibles the max current is usually
at the maximum listed voltage (33v for 24v units). For unfiltered FWR ratings, see installation instructions.

ARCHITECTS AND ENGINEERS SPECIFICATIONS
General
Audible/visual notification appliances shall be listed for indoor use and shall meet the requirements of FCC Part 15 Class B. These
appliances shall be listed under UL Standard 1971, (Standard for Safety Signaling Devices for Hearing Impaired) and UL Standard 464
(Fire Protective Signaling). The appliances shall use a Patented Universal EZMount backplate that shall allow mounting to a singlegang, double-gang, 4-inch square, 4” octal, or a 3-1/2” octal backbox. Two wire appliance wiring shall be capable of directly connecting
to the mounting back plate. Continuity checking of the entire NAC circuit prior to attaching any audible/visual notification appliances
shall be allowed. A dust cover shall fit and protect the mounting plate. The dust cover shall be easily removed when the appliance is
installed over the backplate. Removal of an appliance shall result in an alarm condition by the Fire Alarm Control Panel (FACP).
Strobes
Strobe appliances shall produce a minimum flash rate of 60 flashes per minute (1 flash per second) over the Regulated Voltage Range
of 16 to 33 VDC and shall incorporate a Xenon flashtube enclosed in a rugged Lexan lens. The strobes shall be available with two
or four field selectable settings in one unit and shall be rated, per UL 1971, for up to 185 cd for wall mounting and 177 cd for ceiling
mounting. The strobes shall operate over an extended temperature range of 32°F to 120°F (0°C to 49°C) and be listed for maximum
humidity of 95% RH. Strobe inputs shall be polarized for compatibility with standard reverse polarity supervision of circuit wiring by a
Fire Alarm Control Panel (FACP).
Audibles and Audible/Strobe Combinations
Horns and horn/strobes shall be listed for Indoor use under UL Standard 464. The horns shall be able to produce a continuous output
or a temporal code-3 output that can be synchronized. The horns shall have at least 2 sound level settings of 90 and 95 dBA.
Synchronization Modules
When synchronization of strobes or temporal Code-3 audibles is required, the appliances shall be compatible with the Wheelock Series
SM and DSM Sync Modules or the Wheelock PS-24-8MC Power Supply with built-in, patented sync protocol. The strobes shall not
drift out of synchronization at any time during operation. Audibles and strobes shall be able to be synchronized on a 2-wire circuit with
the capability to silence the audible if required. If the sync module or power supply fails to operate (i.e., contacts remain closed), the
strobes shall revert to a non-synchronized flashrate
