PROGRAMMING OPTIONS

There are several AK-21 programming options. For most

installations, the factory set default options are sufﬁ cient. The

keypad must be in Programming Mode to make these changes.

Select Door Sense or Inhibit Input Default: Door Sense

The input on Terminal Block TB1, Terminal #8 can be programmed for DOOR

SENSE or INHIBIT.

Press: 1 0 # Input #

Input = 0 for Door Sense, = 1 for Inhibit

When programmed for DOOR SENSE, if an open condition on the input occurs

before access is granted (with an entry code or with the request-to-enter input) a

FORCED ENTRY output will occur. If an open condition remains 60 seconds after

a relay activation for access, a DOOR AJAR output will occur.

When programmed for INHIBIT, a closed condition on the input will prevent

Relay #1 from activating when access is requested with an entry code. This mode

is typically used with an external timer to disable the access device at certain

times.

Select Forced Entry Output Default: Output #3

Sets which output activates if the DOOR SENSE input opens before access is

granted. This output is not timed.

Press: 1 1 # Output #

Output = Output to Activate (0-4)

1 = Main Relay 2 = Auxiliary Relay 3 = Output #3 4 = Output #4 0 = No Output

Select Door Ajar Output Default: Output #4

Sets which output activates if the DOOR SENSE input stays open 60 seconds

after access is granted. This output is not timed.

Press: 1 2 # Output #

Output = Output to Activate (0-4)

1 = Main Relay, 2 = Auxiliary Relay, 3 = Output #3, 4 = Output #4, 0 = No Output

Select Keypad Lockout Output Default: No Output

Sets which output activates when the keypad is “locked out” after too many

incorrect entry code attempts. The lockout time is 60 seconds.

Press: 1 3 # Output #

Output = Output to Activate (0-4)

1 = Main Relay, 2 = Auxiliary Relay, 3 = Output #3, 4 = Output #4, 0 = No Output

Select Keypad Active Output Default: No Output

Sets which output activates when any keys are pressed. This output is timed. If

toggle mode is selected for the output, the timer value defaults to 2 seconds.

Press: 1 4 # Output #

Output = Output to Activate (0-4)

1 = Main Relay, 2 = Auxiliary Relay, 3 = Output #3, 4 = Output #4, 0 = No Output

Select Alarm Shunt Output Default: No Output

Sets which output activates during the time access is granted. (Use this output

to shunt alarm contacts attached to the access door.) This output may be timed

or toggled.

Press: 1 5 # Output #

Output = Output to Activate (0-4)

1 = Main Relay, 2 = Auxiliary Relay, 3 = Output #3, 4 = Output #4, 0 = No Output

Select Request-to-Exit Output Default: Main Relay

Sets which output activates when the Request-to-Exit input is grounded. This

output may be timed or toggled.

Press: 1 6 # Output #

Output = Output to Activate (0-4)

1 = Main Relay, 2 = Auxiliary Relay, 3 = Output #3, 4 = Output #4, 0 = No Output

Main Relay On-time Default: 2 Seconds

Sets the length of time the Main Relay activates when triggered.

Press: 2 1 # Seconds #

Seconds = Output time in seconds (0-60)

Auxiliary Relay On-time Default: 2 Seconds

Sets the length of time Auxiliary Relay activates when triggered.

Press: 2 2 # Seconds #

Seconds = Output time in seconds (0-60)

Solid-state Output #3 On-time Default: 2 Seconds

Sets the length of time Output #3 activates when triggered.

Press: 2 3 # Seconds #

Seconds = Output time in seconds (0-60), 99 = Toggle Mode

Solid-state Output #4 On-time Default: 2 Seconds

Sets the length of time Output #4 activates when triggered.

Press: 2 4 # Seconds #

Seconds = Output time in seconds (0-60), 99 = Toggle Mode

Set Downlight On-Time Default: 2 Minutes

Sets the time duration that the downlight remains on after a key press.

Press: 2 5 # Duration #

0 = Always off, 1 = 1 minute, 2 = 2 minutes, 3 = 3 minutes,

4 = 4 minutes, 99 = Always on

Beep Sounds on Keystrokes Default: Yes

Selects whether or not the keypad beeps as each key is pressed.
