The advanced units also retain the function of all safety devices and accessories such as photoelectric sensors, card readers, telephone entry systems, digital keypads, etc., while the unit runs on battery power. We do this through the use of our special inverter, which converts the energy stored in our back-up batteries from DC to AC power. Installation by a Non-Qualified person could result in injury or death. We sell over 250,000 items from over 500 manufacturers and have access to thousands more. Volume discounts available.
