Alarms & Sirens - SMAC series

Piezo acoustic components are more and more used in small portable equipment and as a critical alerting device.  Reliability must be very high in the most difficult environmental circumstances, such as extreme and varying temperatures, vibrations, shocks, dust conditions, humid environment, etc. 

The SMAC-25 buzzer, manufactures with over 30 years of experience in the field of piezo acoustic technology, is a very stable buzzer with a lifetime of more than 1.000 hours in continuous use.  In these small dimensions, the SMAC-25 is actually the best available piezo alarm for life supporting systems.
