Please read CAUTION and Notice in this catalog for safety. This catalog has only typical specifications. Therefore you are requested
to approve our product specification or to transact the approval sheet for product specification, before your ordering.
Piezoelectric sounder self drive type requires only
simple circuit and DC power supply. Since this type
uses resonant system, it is also available for alarms
which need large sound volume.
• Gas alarms, burglar alarms, smoke detectors.
• Air conditioners, Microwave ovens, washing machines
• Bicycles, toys, game machines.
