Note:
PLEASE ALSO REFER TO THE NOTES ON PAGE 6 FOR MORE GENERAL INFORMATION.
• The electromagnetic or electric door lock operation is the same as page 6.
• Relay output #2 controls the arm/disarm of the alarm control panel. Consult the alarm control panel manual for more
information.
• Connect the duress output to a 24-hour N.O. zone and the tamper output to a 24-hour N.C. zone on the alarm control
panel.
• The keypad's terminal ground (-) connects to the ground (-) wire of the alarm control panel to enable the two to work
together.
WIRING:
Example Wiring, with Connection to Lock Device and Alarm Arm/Disarm
Interlock
--
Each keypad can be used as a stand-alone keypad. The mantrap feature is for a protected area with
two doors to ensure only one door is open at a time. With the mantrap feature, when a user keys in the code to
open one door, a signal is sent to the second keypad to disable it, thereby preventing access through the second
door until the first door is closed.
Note: PLEASE ALSO REFER TO THE NOTES ON PAGE 6 FOR MORE GENERAL INFORMATION.
• Use an N.C. magnetic contact or some other N.C. device to detect whether a door is opened or closed. Do this
for the two entrances to the protected premises.
• Combine this wiring diagram with the diagram on page 7 if connection to an alarm control panel is required.
• Connect output #2 to relay output #1 disable as shown on page 6 if inhibit control is required.
• To use the mantrap feature:
o Use either the keypad from outside or the egress button from inside the protected premises to open one of
the two doors.
o While the first door is opened, the first keypad sends a signal to the second keypad to prevent the second
keypad from being used to open the second door.
o After the first door is closed, both keypads are ready to use.
