Testing The Keypad - Chamberlain APEX Access Device Installation And Operation Manual

Using Extended Door Controls
The extended door controls function allows comprehensive access
management. Door controls are designed for use with a door to a
building but can be used for a gate or other access device. There are four
connections used by the extended door controls. Input 1 is used for the
door alarm contact, Input 2 is used for the request to exit device, Relay 1
is used to trigger the door strike, and Relay 2 is used to activate a door
holder. When the extended door control function is enabled, the other uses
of these inputs and relays are disabled.
Operation of this function depends on having a door equipped with both
a door strike and a door alarm contact. The door strike will be connected
to Relay 1 and the door alarm switch will be connected to Input
APEX activates Relay 1 for the Door Strike Time entered during setup
programming. This allows the APEX device to activate the door from
request to exit device. Relay 1 will activate the door strike when a valid
access command is sent from the controller. This is the only case in which
the hold time for Relay 1 is not determined by the controller. Instead it is
set by the Door Strike Time parameter Setup Function. Once the door
strike is activated, the door can be opened.
To prevent the door from being held or propped open, the Max. Door Open
Time parameter can be set in the Setup function. If the door is held open for
longer than the time specifi ed by the Max. Door Open Time, the controller
will respond with an alarm and the Door Held Open message. When the
door is closed, the controller will report Door Closed.
A request to exit (RTE) device is typically a push button or motion detector
designed to open a door from the inside. If an RTE device is added to
Input 2, the door strike will be activated by the controller or by the signal
from the RTE device. If the door is opened without Relay 1 being active,
the controller will respond with an alarm and the Door Held Open alarm
message.
If an optional door holder is used, Relay 2 will control that device. When
the door is opened by the controller or by the RTE device, Relay 2 will
activate to turn on the door holder and hold the door open. To use a door
holder, Relay 2 must be set for DIFFERENT HOLD TIME in the APEX
Device Setup Function. The amount of time the door is held is specifi ed by
the Relay #2 Hold Time parameter. This time must be set to a value less
than the Max. Door Open Time to avoid false alarms.

Testing the Keypad

1. Test the display by applying power to the keypad. The default date
and time should appear on the display after power is applied. The
controller updates the date and time to the keypad once a minute.
The date and time on the display should update if the keypad is
confi gured correctly. To verify that the backlight is working, press the
* key. The backlight should come on and the display will read Please
Enter Access Code. If no keys are pressed for 10 seconds the
display will return to the Date/Time and the backlight will shut off.
2. To test touchpad operation, press the * key. When the display shows
Please Enter Access Code, press 0, 1, 2, 3, 4, 5, 6, 7, 8, 9. You
should see each digit appear on the display as it is pressed (you will
a see an X for each digit if Secure Entry is enabled). After pressing
the # key to transmit the code to the controller, the display will show
Please Wait until a response is returned from the controller. If the
keypad is communicating with the controller, the display will show
either Entry Granted or another corresponding message.
3. Test for communications with the controller by applying power
to the controller. The date and time at the controller will
automatically update on the keypad and appear in the display. This
verifi es communications from the controller to the keypad. Test
communications from the keypad to the controller by entering an
access code into the keypad and pressing the # key.
4. If the keypad display responds with anything other than Please Wait
before returning to the date and time, the keypad has successfully
communicated with the controller. If only the message Please Wait
appears before the keypad defaults back to the power-up default
time of 12:00, recheck the wiring, Baud rate settings, and dipswitch
settings. Also ensure that the controller is set to the correct number
of remotes.
