SK-ACP Installation & Operating Manual
POWER & BATTERIES
The SK-ACP unit must be connected to a source of low voltage power. The SK-ACP should NOT be connected to
the same power supply that is providing power to an electric lock or strike. We recommend that you use the
Secura Key SK-ACP-PS, which includes a 24 VDC, 500 mA transformer and a 12VDC, 1.9AH standby battery, to
power the SK-ACP.
Terminals 7 & 8 on plug “J7” must be connected to 16.5 to 24 volts, AC or DC. You may also connect the SK-ACP
to 12 VDC, but in this case you must connect your power supply to the red (+) and black (-) wire leads on the lower
left corner of the panel instead of the “J7” plug. If you use 12 VDC you cannot install a standby battery in the SK-ACP.
When 16.5 – 24 volts is used to power the SK-ACP, you may connect the red and black wires to a 12 volt standby
battery. Polarity (+/-) must be observed. The standard SK-ACP has space for a small (1.9AH) battery, while the
10” X 11” SK-ACP-LE can accommodate larger batteries. A battery up to 4.5 Amp-hours can be connected to each
SK-ACP.
Do not energize the SK-ACP until all other connections are made.
READERS
SK-ACP is designed to accept any reader or keypad with a standard Wiegand interface. The reader for door #1 is
connected to plug “J5”, the reader for door #2 is connected to plug “J6”. (See figure 3) SUGGESTED CABLE IS
Eastman 725-5720 SJ. The SK-ACP will provide up to 150mA to power each reader. If the readers you use require
more current, an external power supply must be used.
INPUTS
Each reader may be associated with up to two auxiliary inputs. Inputs might include remote switches, door contact
sensors, vehicle presence detectors, etc. If you connect inputs to the SK-ACP you must define those inputs using
SK-NET™ software (see SK-NET™ manual, section 5.31). Note that input 1 (#7) and input 2 (#9) share a common
terminal (#8) on plugs “J1” and “J2”. All inputs are configured as normally open circuits. However, in many cases a
“Door Monitor” input should be a normally closed circuit. To convert any input defined as “Door Monitor” to normally
closed, disconnect power from the panel, remove the jumper from pins 3 and 4 in the J9 expansion slot and place
the jumper on pins 4 and 5. Restore power to the panel and test the “Door Monitor” input.
OUTPUTS
Each door controlled by the SK-ACP has two double pole, double throw relays associated with it. The “latch
relays” are located on “J1” and “J2”, terminals 1-6. The “auxiliary relays” are located on “J3” and “J4”. One pole of
the latch relay is typically used to open or close a circuit to unlock a door or activate a gate operator. The other
pole of the latch relay operates simultaneously and may be used to shunt an alarm contact, start a video recorder,
etc. The auxiliary relay may operate according to a variety of user-defined conditions. These must be
