Why does the Bell System CS106 Keypad lock operate from the test button but not when the code is entered?
If the Bell System Keypad lock operates from the test button but not when the code is entered, first check that the Keypad is correctly programmed. If it is not, restore it to the Factory Settings. Additionally, verify that the Time Clock is in the correct state; if not, reprogram the action code or manually switch the time clock.
What to do if the Bell System CS106 lock release does not operate when the Exit Button is pressed?
If the lock release on your Bell System Keypad fails to operate when the Exit Button is pressed, test by applying a short-circuit directly to the ‘EXIT’ terminals. Also, check the connections to the Exit button.
What causes the Bell System Keypad lock release to be permanently active?
If the Bell System Keypad lock release is permanently active, temporarily remove the connections to the ‘EXIT’ and re-test the unit. Also, check that any exit button connected to the EXIT terminals is ‘push to make’ and not the opposite.
What does it mean when the red and green LEDs flash together on a Bell System Keypad?
If the red and green LEDs flash together when attempting to operate the lock-release on your Bell System Keypad, it indicates that the fail-secure lock release output is short-circuited or of an incorrect rating. To resolve this, temporarily disconnect the lock release and retry to see if the green LED turns on for 3 seconds. You may also need to test the lock release.
Why can’t I change settings on my Bell System CS106 when the green LED is on?
If you can’t change any of the settings on your Bell System Keypad and the green LED is on, it could be due to short-circuited ‘EXIT’ terminals. To fix this, temporarily remove the connections to ‘EXIT’ and re-test the unit. Also, check that any exit button connected to the EXIT terminals is ‘push to make’ and not the opposite.
What to do if the Bell System Keypad lock release fails to operate when the Test button is pressed?
If the Bell System Keypad lock release fails to operate when the Test button is pressed, check the lock release and its wiring by moving the lock connections to + C, -H, (forcing the lock). Also, measure the voltage on the FAIL SECR terminals; this should be the same as the power supply (13.8V) while the test button is pressed.
How to fix a Bell System Keypad when the lock release operates in reverse?
If the Bell System Keypad lock release operates in reverse, transpose the connections between the fail-safe and fail-secure outputs.
What to do if nothing happens when power is applied to the Bell System CS106 Keypad (LEDs do not flash)?
If nothing happens when power is applied to the Bell System Keypad (LEDs do not flash), it could be due to several reasons. First, the power supply might be overloaded, so remove externally connected components until the fault disappears. Second, the polarity might not be correct, so measure the voltage at the C106 (+, -). Finally, check the power supply fuses and replace them with fuses of the correct type and rating if necessary.
