A security system with a driver circuit for energizing a solenoid actuated locking device. The circuit can include a microprocessor, a battery power supply, a boosting circuit and an energy storage circuit. The battery voltage can be stepped up by the boosting circuit and the stepped up voltage can be stored in the energy storage circuit. A solenoid driver circuit including a plurality of transistors arranged in an H-bridge configuration supply energy from the storage circuit to the solenoid under control of the microprocessor. The security system can be retrofited or is factory installable, and is particularly adapted for roll down doors and enclosures.
