General :Audio Visual Alarms are manufactured as per requirements of D.G.M.S circular No. 7 of 1977 which stipulates that an audio visual warning device should be provided on the rear side of HEMM of tippers to warn the persons that the vehicle is being reversed and that the sound of the device should be different that conventional horns.Design :In order to comply with the requirements of the circular, the design comprises of an electronic device which produces sound of variable pitch and a visual device which generates flashes at 60 to 80 per minute. The audio output is 10/15 watt and visual output is designed according to requirement i.e. 21 watts or 60 watts.Decibel Level :Alarms are tested for minimum decibel level of 100. It is possible that some Alarms have db level of more that 100 because of impedance of the speaker which the company procures from other manufacturers.Construction :The firm is marketing four models namely 24v with 21 and 60 watt flashers and 12v with 21 and 60 watt flashers.Guarantee :The Alarm is guaranteed for 12 months from the date of dispatch. The guarantee does not cover physical damage to the container.

This Multi-Tone Siren Circuit enables the users to select Police, Ambulance, and Fire & Staccato siren with 8W amp O/P. The siren kits available in the market generate normally a single tone. With Multi-Tone Siren, one can generate different types of siren tones for different purposes like ambulance, police fire, etc. This unique feature of the circuit makes it versatile and useful in wide range of applications like burglar system, lift door open alarm, smoke detector and any other alerting application.About the circuit :Versatile UM 3561, 8 pin IC is used here to generate four different audible ones. Basically IC has built in oscillator, control circuit, address counter, ROM and Tone generator etc .The predefined programs generate different tones only with few external components. The IC operates at low voltage of 3 volts upwards. Its quiescent current is as low as 150 microamperes.A single resistor between pin7 and pin 8 decides the frequency of oscillations. Pin 1 and 6 are tone selector pins. The center - off toggle switch S1 helps in selecting the tone desired in the output. Output is available on pin 3.The selection table gives the switch poison and tone selected. The power supply used is from eliminator or battery measuring about 3-9 volts. A zener D1 of 2.7 volts is used to regulate the supply forIC1. R2 is the biasing resistor for zener D1.   The AF section consists of IC2, which is low power audio amplifier IC specially designed to deliver 1 – 8 watts of power at 4 ohms load (Speaker).The output of this amplifier exhibits low distortion and low noise. The input to this amplifier is fed through pin 3 through variable resistance VR1 to adjust the input signal. This acts as volume control. The output of this amplifier (pin 7) is fed to the speaker.

• Tone frequency range: 300Hz to 1000Hz

We are leading manufacturing organization in Central India for the safety products used in mines audio visual alarm (AVA) are approved. We have received the DGMS approval of Audio Visual Alarm for 24 V DC & 12 V DC for H.E.M.M. & Surface Transport Machineries.As the size of the dumper and other Heavy Earth Moving Machinery (H.E.M.M.) is so big that it is impossible for the operator to see the back side of the H.E.M.M to get Alert an avoid the accidents.It is must that the alarm with Visual Indicator should be provided to the person who is standing behind the H.E.M.M According to the D.G.M.S., the maximum number of fatal accident occur during reversing of surface transport Machineries in open cast mines.
