AL310 series beacon siren Application Designed for the operation warning or auxiliary alarming for the hoist machinery, construction machinery, pavement construction machinery and port machinery. Also applied for the facilities of mine, metallurgy, chemical industries, marine or vessels, etc. Major functions and features • Aluminium body, impact structure, light weight and excellent corrosion resistance Good seal capacity features the superb waterproof and dustproof performance. Warning light use ultra bright LED, combined with strobe mode. It is good at warning effect, Wall-mounted/plane-mounted to meet various installation requirements and anti-vibration. shock resistance, long life and other characteristics. • Employ the industrial grade digital and audio chip to guarantee the high stability and EMI Model One：Optionally use wiring harness to remotelly switch the tones, at most switch 5 tones with its corresponding working state Model Two：use internal dial switch to set up the tone (16 kinds) Specifications Operating voltage Wiring diagram AC220±10% / DC24V±20% （other can be customized） Model 1:A/B/E/D/whistle（optional） remote switchover Model 2: 16 kinds of tones（See tone table） dial switch Power consumption Warning mode Sound and light signal Operating temperature Installation • Please make sure the logo side shall be right above, and then fix it onto the mounting surface which should have enough smoothness and mechanical strengthen with 4*M6 screws • The angle between speaker and horizontal plane should be less than 90°. To protect the sound from the water accumulation in the speaker. • Tone model 1: Connect the power cable and control cable through the cable connector. Refer to the wiring diagram of model 1 and remarks on the cable to make the connection and be ensure the input power is same as the working voltage of the beacon siren. Siren and beacon will work synchronously along with control signal. • Tone model 2: Take off the front cover. For AC voltage, please refer to Picture 1 and wiring diagram of model 2 (picture A), to make the power cable connected with terminals. For DC voltage, please refer to Picture 1 and wiring diagram of model 2 (picture B) to make the power cable connected with the terminals. There are 4 nos dial switches on the PCB board, corresponding to 16 kinds of tone. Refer to the tone selection table to choice the tone. Be ensure the power voltage is same as the working voltage. • Refer to below picture 2 to switch over the tone. After selecting model 1, power it on and the indicator light on PCB is flashing. After selecting model 2, indicator light is steady on.
