OUTPUTS

Each door controlled by the SK-ACPE 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 programmed using SK-NET™ software (see SK-NET™ manual). NOTE: Two MOVs (metal-

oxide varistors) are provided with each SK-ACPE. These must be installed between the “Common” and either 

the “Normally Open” or the “Normally Closed” terminals where power to the electric lock or strike is being 

switched (See Figures 7 and 8). For testing and troubleshooting purposes, an LED indicator is located on the 

circuit board adjacent to each relay.  The LED lights when the relay is activated.  

COMMUNICATIONS JUMPER

The jumper on pins  2 and 3 of Jumper connector JP1 must be installed to enable RS-232 communications 

at Jack J11 and J7.  If the SK-WLSE-MOD Wireless network module is installed at J12, this jumper must be 

moved to pins 1 and 2 of JP1 to enable RS-232 communications with the wireless module.

LED INDICATORS

The  SK-ACPE  features  12  LED  indicators,  which  will  assist  the  installer  when  connecting,  testing  and 

troubleshooting the readers, inputs and outputs, power and communications wiring. These indicators and 

their functions are described in Figure 4.
