SA-A1_CZ_P_125 W2

Signalling device SA-A1 Product description The signalling device SA-A1 enables generation of five acoustic signals. Releasing an acoustic signal is done through connecting the appropriate control input to gnd. Additionally, the signalling device has got the input enabling operation in the lowered volume mode. The casing of the signalling device is made of plastic ABS, PC. Elements are permanently joined. The sound source is a piezoceramic transducer. The signaling device has got a straight or angular fastening to the ground/wall. Control options The acoustic signal is released through connecting the appropriate control input to gnd. The signal is generated as long as the signalling device input is connected to gnd. The electronic system of the signalling device has got the built-in priority mechanism, it means that in case of occurring two signals simultaneously, the system will start generating the signal of higher priority (the highest priority has got the input S1). The signalling device SA-A1 can also operate in the lowered volume mode. In case when the input VOL will be connected to gnd, the electronic system built-in the signaling device will reduce the volume of emitted sound. This state will last as long as the input VOL of the signaling device will be connected to gnd. Connection diagram Control input Acoustic signal S1 (red colour) Increased frequency from 2400Hz to 2850Hz during 0.14s S2 (yellow colour) Frequency 2850Hz: serially 60ms of sound, 120ms of silence S3 (green colour) Continuous sound with fixed frequency (300Hz) S4 (blue colour) Serially sections of 0.5s with the frequency of 800Hz, 700Hz S5 (white colour) Frequency 3000Hz, 3 bundles of pulses with the time duration of 32ms each one (sound and silence of 16ms) separated with the silence of 0.5s, and then 1.5s of silence
