The feature will operate when the door has been released from the keypad or from the REX input (see Section 3.6). Note that to disable the anti-tailgating feature and return full function to the HCD and UCD terminals, put the unit into program mode and enter 8-4. Note that the DK- 26 supports a more powerful anti-tailgating feature which incorporates an alarm signal through the use of the programmable relay. Read Section 6.4 for details.
7.5 WIRING WITH SECURITRON'S TOUCH SENSE BAR AND MAGNALOCK
The DK-26 is often used with Securitron's Touch Sense Bar and magnetic lock. The following drawing shows wiring for this particular configuration. Note that the REX input is not used. Since touching the bar opens the door in a single motion, you do not want to activate the DK- 26's timer which would only serve to keep the lock released for a longer time, thereby reducing security. Another potentially confusing element is that the Touch Sense Bar is also a powered device which operates most reliably when it is constantly powered. The drawing shows a wiring method that is applicable for either an AC or DC power supply (naturally, the supply voltage must be matched to the lock voltage). Note that a variation of this wiring scheme could be desired if you are using the second pole of the DK-26’s lock control relay to shunt an alarm system (see Section 7.3). You would then want the Touch Bar to operate the DK-26’s lock control relay in double break fashion so that the alarm system is shunted both for entry and exit. Simply follow Figure 9 except also connect the blue and orange wires from the Touch Sensor to terminals SRC and REX on the CPU board (as well as connecting the second pole of the lock control relay to the alarm point as shown in Section 7.3).
