Security Electronic Access Switch I-KEY Publication Number: PB191/0412 System Explanation The Dewhurst I-KEY Security Access Switch is a general purpose security module. It uses iButton type touch memories to identify the keys. If a predefined key touches on the stainless steel probe, I-KEY shorts the relay contacts for five seconds and leaves the contacts open after this period. I-KEY warns the user with visual and auditory ways with on-board beeper and in-probe LED ring. I-KEY can be easily programmed with on-board pushbuttons. The end users can create their own MASTER KEY to record a new key to the module memory. Installing the Module Apply 24V d.c. current on the POWER terminal of module. You should hear a BEEP sound and RED colour on the probe when you energise the module. Operation voltage has to be between 18-28V d.c. Please do not exceed this limit. Clearing I-KEY Memory (Memory Reset) Press and hold the REC + DEL buttons for 3 seconds. Recording a New Key into I-KEY Memory Click on the REC button on the module. You will hear a beep sound and probe colour will blink repeatedly in yellow and then in green colours. In this period, you can touch the new keys, which you want to add into the I-KEY memory. Module will exit from the recording mode if you do not touch any key on the probe in five seconds. Creating a MASTER KEY I-KEY can be put in LATCHING MODE only with a “MASTER RECORD KEY” To create a master key, follow the below steps: 1. Power ON I-KEY; you will hear a beep sound and probe colour will be solid RED 2. Press and hold the REC button 3. Without releasing the REC button, touch an I-KEY-FOB on the probe and release the REC button. You will see that the probe illumination is OFF 4. Release I-KEY-FOB; wait for 5 seconds until probe colour is RED Now we have a MASTER RECORD FOB To enter Latching Mode, touch MASTER RECORD FOB on probe and wait for 5 seconds until you hear the LONG beep sound. I-KEY will enter into Latching Mode and will exit from this mode only if: - The probe is touched by a MASTER RECORD FOB - The REC or DEL key is pressed - The probe is touched by a previously recorded key Using MASTER KEY to record a new key into I-KEY Memory Touch the MASTER KEY into the probe. You will hear a beep sound and probe colour will blink repeatedly in yellow and then in green colours. In this period, you can touch the new keys, which you want to add into the I-KEY memory. Module will exit from the recording mode if you do not touch any key on the probe in five seconds. Deleting a Previously added Key from I-KEY Memory Click on the DEL button on the module. You will hear a beep sound and probe colour will blink repeatedly in yellow and then in red colours. In this period, you can touch the previously added keys to remove from the I-KEY memory.
