Connecting To A Door Strike - Chamberlain LiftMaster Q Installation Manual

block at the lower right corner of the board (P4). Make sure the signal
from the operator meets the electrical specifications for the relays. DO
NOT USE ANY HIGH VOLTAGE SIGNALS. The pin connections for the
connector are as follows:
Pin 1 – Relay 1 Normally Open
Pin 2 – Relay 1 Common
Pin 3 – Relay 1 Normally Closed
Pin 4 – Relay 2 Normally Open
Pin 5 – Relay 2 Common
Pin 6 – Relay 2 Normally Closed
A gate operator can be connected to either relay depending on how the
Q Access Keypad is set up. If desired, more than one operator can be
connected to a single keypad. If two or more keypads trigger one gate,
the gate only needs to be connected to one of the devices. For security
reasons, the gate operator should be connected to the Q Access Keypad
being used for exit. This prevents someone from accessing the site by
vandalizing an entry Q Access Keypad.

Connecting to a Door Strike

A door strike connects in a similar manner to a gate operator, with the
exception that the door strike requires power to operate. The power
supply required will depend on the type of door strike and must be
supplied by an external power supply. Do NOT use the same power
supply that provides power to the Q Access Keypad. See Figure 7 for
details on connecting the door strike.

Maximum Attempts Check
The maximum attempts security check is designed to discourage
someone from attempting numbers at random to enter the site. If the
Max. Attempts before Lockout feature is set to a value other than zero,
the keypad will check to see if the user has tried a code more than the
allowed times. If not, the keypad will proceed to the next security check.
If the maximum number of unsuccessful attempts has been exceeded,
the keypad will display the following message and disable any further
access attempts. The keypad will not allow any further attempts until it
has had 60 seconds without any key being pressed. If a key is pressed
while this message is displayed, the 60 second timer starts over.
* WE'RE SORRY *
PLEASE SEE THE
MANAGER
Trip Relay Offline Check
The final security check for the Q Access Keypad is to check the Trip
Relay Offline option. If it has been enabled, the keypad will allow the
access process to continue. If it has been disabled and the keypad is not
in communication with the controller, then the keypad will display the
following message and no further access attempts will be allowed.
* WE'RE SORRY *
THIS DEVICE IS OUT OF
SERVICE. PLEASE SEE THE
MANAGER
Once the controller has gone through its security checks, it will verify the
code and send a response to the Q Access Keypad. The response
message will be displayed. The messages that can be received from the
controller vary depending on the type of response.
Customer Code Entry
When the Q Access Keypad is set to use access codes, all the customer
needs to do is enter his or her access code using the touch pad. When
they approach the keypad, one of the standard or custom messages will
be shown on the display.
