Appendix V: Changing i-rk01 From Four to Six
Digit Access Codes
50 160
The i-rk01 can be programmed to give either four or six-digit access codes.
Doing this requires you to remove the batteries and re-insert them. Make sure
that the control unit is in Installer Mode first in order to avoid tamper alarms.
Note: Make sure that you have changed the control unit to use the same
number of digits in access codes as you intend to use on the i-rk01. You
cannot use six digit codes on the i-rk01 and four digit codes on the
control unit (or the other way round).
To Change The Number Of Access Code Digits:
1. Enter Installer Menu at a wired keypad.
2. Open the i-rk01 and remove the front from the case back.
3. Remove one battery.
4. Wait approximately 20 seconds for all residual charge to drain from the
i-rk01‘s circuits.
You can test that the i-rk01 is completely discharged by pressing the
―A‖ key. When you do so there should be no flashing LEDs or keyclicks.
5. For six digit codes; hold down keys ―A‖ and ―6‖.
For four digit codes: hold down keys ―A‖ and ―4‖.
6. Re-insert the battery you removed in step 3.
7. Release the keys you were holding down.
8. Re-fit the front of the i-rk01 to the case back. Make sure that the
tamper switch operates.
9. Leave Installer Mode.
