The six digitized alarm sounds of the FK278 are held permanently in a masked Read Only Memory (ROM) in a decoder IC. A transistor output amplifier drives the supplied 8 Ohm 0.25W speaker for a demanding sound suitable for toys and novelty applications.
When powered on, the alarm plays all 6 sounds in sequence and will loop from the start again, until the power is removed.
