Sonitron sirens generating clear warning signal

One of the most important ones is frequency, sound level (volume), type of sound (continuous, intermittent, sweep) and also the overall noise in the given environment (from traffic, machines, people).

Some typical tones have proven to be very easily audible over the years, even in very noisy environments. Naturally, that is why many vehicles produce more or less very similar sound for warning at the reverse movement.

Typically those are low frequencies in a range of approximately 1000 -2500 Hz. That's also why Sonitron, one of the world leaders in piezo technology, produces its SAP-1302 series with these frequencies and a typical intermittent sound (1Hz).

Usually, the SAP-1302 series are installed at the back of a car, truck, tractor, jeep, golf-trolley, ... or any other vehicle that can move in reverse at any moment, thus alerting people approaching the vehicle.

The quality, longevity and reliability are key factors at production; the SAP series are tested for use under all weather conditions IP67 and have a lifetime in continuous use of more than 1000 hours.

There are 4 basic versions of sirens available, differing in the frequency of the sound as well as its volume:

For easier use, Sonitron offers different connection versions, either with fastons or with a cable:

SAP-1302-A/B/C/D-F2 Fast-on F2, tinned brass 
SAP-1302-A/B/C/D-W standard cable length=30cm
