Other Details:
Director General Mines Safety (DGMS) has observed that maximum number of fatal accidents have occurred in open cast mines while reversing of Heavy Earth Moving Machinery (HEMM) especially in dumpers/tippers.
 
Size of the dumpers are so big that it is impossible for the dumper operator to see the back side of the vehicle.
 
Therefore, in order to avoid accident, during reversing, Audio Visual Alarm is required.
 
To reduce such accidents DGMS made it compulsory to install Audio Visual Alarm (AVA) in every HEMM and Surface Transportation Machineries used in Mines.
 
DGMS issued technical circulars time to time such as Circular No. - 09 of 2003, Circular No. - 04 of 2008, Circular No.- 01 of 2010, Circular No. 1 of 2012, in these circulars DGMS has clearly mentioned technical specifications and testing parameters for AVA.
 
Due to change in DGMS approval policy, all previous approvals withdrawn and technical specification with testing parameter has being issued vide Circular No.- 01 of 2010.
 
Our Audio Visual Alarm has been tested and found satisfactory by the Government Testing Laboratory mentioned in DGMS Circular 1 of 2010.
 
Technical Specifications:
Audio: Two synchronized speakers, having sound. To make the fail-safe, two speakers are arranged in such a way that if any fault occurs in one speaker other will work without any interface. (DGMS requirement: Two speaker with 110 dB output)
 
Visual: Bright focus type Red LED blinks continuously while reversing emitting uniform light. Brightness recorded from distance of 300 mm. (DGMS requirement not less than 300 Lux)
 
Protection: Tested as per as per DGMS Circular No. 01 of 2010. The electronic circuits and speakers are totally sealed by epoxy resin, so that nothing can enter in it. Our Audio Visual Alarm is 100% Water Proof. It even works after totally immersed in water. It does not have free space to accumulate ingress dust/water into its enclose. (DGMS requirement not less than IP 67)
 
Timer: To reduce the noise pollution and also to protect the AVA, timer is provided which shut sound automatically but the light continues to flash. (as per DGMS requirements).
 
Color: Black powder coated, (Siemens Gray, Yellow, or as per requirement).
 
Marking: Serial number, Batch number, Date of manufacturing on each AVA. (as per DGMS requirements)
