Features:

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.
