The Pertronic DUALSTROBE is a compact unit providing both Alert (Amber) and Evacuate (Red) strobe outputs which can be driven on a 2, 3 or 4 wire 24V system. A two part installation makes the fitting, connection and servicing extremely simple whilst the size of the unit makes it aesthetically pleasing. At only 50mA average current draw per strobe, and a flash rate of 1.1Hz, the unit is very energy efficient.
