Siemens ZH-W Notification Appliances feature easy snap-on base designed to simplify the installation and testing of horns, strobes, and horn/strobes. The separate Series Z snap on base pre-wired so circuit wiring can be fully tested before the appliance installed and before the walls are covered. Once all surrounding work is complete, the appliance can be simply installed by snapping 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 for all Series Z horns, strobes and horn/strobes to provide consistent installation and easy replacement of appliances if required.
A locking screw included for the appliance to provide extra secure installation. Also, the Series Z appliances incorporate the same dependable circuitry and high efficiency optics used in ST strobes, including the Siemens ZH-W.
