Siemens ZR-HMC-W

The 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 snapping it on the base.
