A bottom keeper failing to release may be caused by inadequate amperage at the strike. Voltage may be in the correct range, but without proper amperage the bottom keeper may not release, or there may be intermittent operation of the 9600 keeper. Verify operation with a good battery or different power supply. It may be necessary to upgrade wire size, or switch to a power supply with more amperage.
All HES electric strikes use DC Solenoids only. The 4500, 5000, and 5200 series can take AC, intermittent only.
The power supply requirements will vary depending on the strike and the quantity and type of auxiliary devices that are going to be used. Refer to the strike installation instructions for voltage and current requirements of the electric strike. Securitron manufactures a broad line of quality power supplies.

Some HES can use A/C power for intermittent operation. Refer to the installation instructions of your particular strike for voltage requirements.
The power consumption for each strike is listed on the front page of the installation intructions and on the label on the back of the strike. Add this number to the total current requirement for all other components you wish to connect to the power supply and multiply that number by a minimum of 1.5. This should allow a sufficient factor of safety to power the components.
