The LF-SI/SS Audible Strobes and Sirens are designed for maximum performance, reliability and cost-effectiveness. It adopts a built-in integrated circuit, a piezoelectric sounder and strobe which when combined, produces high energy conversion efficiency for effective output of light and sound while utilizing a minimum amount of power.
Vimpex has incorporated a number of innovative lens and LED light technologies into the VAD23 Range that maximises light output for minimum current. With models that combine both a traditional electronic sounder or a voice sounder with a low current EN 54-23 rated VAD, the VAD23 is truly the most versatile family of visual alarm devices currently available - providing flexible solutions for the designer and end-user.
The Zeta addressable input unit (ZIU) is used to interface external equipment which has a volt free normally open relay output to any Zeta addressable fire alarm system. The input is monitored with a 47K end of line resistor.
