Accommodated inside our deep base, GFE-BASE-BUZ has a built-in piezo buzzer and it's
an option for local alarm signalling in places like offices, hotel rooms and classrooms
at a lower cost than a VULCAN 2 base sounder.
GFE-BASE-REL has a relay which is a very practical solution for ventilation
damper activation together with UG-4, our single-pipe duct smoke detector.
All options are loop powered making them a viable and low cost solution for
localized audible notification and external activation.
