The ABB-1033 box is constructed of steel with a durable beige powder coating finish to prevent corrosion. It operates on 12V DC and draws a low 60mA. The ABB-1033 implements an exclusive low current patented motor driven bell mounted to a removable inner baffle plate and generates a sound output of 85 dB at 10 ft. in the open field. Two reed plunder switches (PSW-1) are designed into the bell box to provide complete tamper protection.
