Specifications

If pressing the TEST button causes the LEDs to flash :

The power supply has been overloaded; look for either a short-circuited across the lock

release output, or check that the power supply rating is adequate for the lock release

used.

Testing the Alarm Outputs

This test should be applied to each channel (Door A or Door B) of the 108 PLUS

seperately

Check that the alarm output is correctly wired to the device being used; ensure the slide

switch is in the ‘RUN’ position. It is advisable to temporarily disconnect the lock release

if it has not already been tested.

Press and hold the TEST button; This should activate the alarm output , the lock

output, and the LEDs. If there is a problem follow the same fault diagnosis procedure

described above for the lock release output.

Testing the Keypad

This test should be applied to each channel (door A or Door B) of the 108PLUS

seperately.

This test makes use of the red and green LED provided on the model 216L keypad. If

another keypad is being used which does not have LEDs it is possible to use the LEDs

on the PCB which duplicate their function; In this case, it may be neccessary to

temporarily relocate the keypad closer to the controller using a short length of cable.

Obviously, if the system only exhibits a fault when the keypad is returned to its position

then the keypad cabling must be the cause.

! Program the unit to Factory Settings (see page 7) and ensure that the slide

switch is returned to the ‘RUN’ position.

! Press the keys in the following sequence (( 9 8 7 6 5 4 3 2 1 0

! If the 108Plus controller reads these keys in the same sequence then the green

LED will flash briefly for each key-stroke.

! If any keys appears out of sequence then the red LED will flash brief. This ends

the test sequence (until the sequence is restarted with the (( key).

! To find more incorrect keys repeat the sequence, replacing the keys found to be

incorrect with the # key (This only works if the # key is correct!).

! A Faulty Row or Column of keys (or more) will tend to indicate a connection fault

(use the key matrix of Diagram 3 to identify faulty connection), whereas a single

faulty key would tend to suggest a faulty keypad.
