KEYPAD WIRING EXAMPLE
See Fig. 3 for an example of a basic door installation. The keypad is
mounted adjacent to the door. An electric door strike is mounted in the
door jamb to release the door lock. An optional door contact switch is
mounted on top of the door jamb for detecting when the door is open.
Use the following steps to wire the keypad. Refer to the wiring diagram
shown in Fig. 4 to assist in the wiring.
Note: For lock power, use 18 AWG wire or larger (depending on load).
Use 22 AWG or larger for signal connections. Refer to lock
manufacturer’s documentation for lock power requirements.
Output Connection
Install a low-voltage fail-secure electric door strike at the door to be
controlled. Route 2 wires from the door strike to the keypad. Connect an
MOV across the coil wires of the strike. Connect the (+) door strike wire to
the keypad’s MAIN RELAY N.O wire (yellow). Connect the other door
strike wire to the keypad’s PWR(-) wire (black). Connect the keypad’s
MAIN RELAY COM wire (white) to the keypad’s PWR(+) wire (red) .
Power Connection
Connect the power supply’s output terminals to the keypad’s PWR(+) wire
(red) and PWR(-) wire (black). If using a DC supply, observe wiring
polarity. If an AC transformer is being used, keypad polarity does not
matter.
Caution: If the unit is AC powered, make sure the secondary of the
system transformer is isolated from earth ground.
Earth Ground
To avoid damage to the unit from static discharges, this unit must be
connected to a proper earth ground. Connect the green earth ground wire
to a good earth grounding point. Suggested wiring size is 18 AWG for
earth ground.
Sense Input
RE
Note: The SENSE input (gray wire) can be programmed as either a
door sense or inhibit input (default = inhibit). Both features cannot be used
at the same time.
Door Sense: (Detect forced entry or door ajar conditions) Install a
normally
closed
door switch on the door and route two wires from the switch to the
keypad. Connect the door switch to the keypad’s SENSE wire (gray/ E8)
and COM wire (any black wire).
Inhibit: (Disable access) If an inhibit switch or timer is going to be used for
temporarily disabling the keypad, route two wires from the switch or timer
to the keypad. Connect the inhibit switch/timer’s
normally open
contacts to
the keypad’s SENSE (gray/ E8) and COM (black wires) terminal.
Request-to-Exit Input
(wiring shown on fig. 4)
If a request-to-exit pushbutton is going to be used, route two wires from
the keypad box to a normally open pushbutton mounted on the secure
side of the door. Connect the wires to the pushbutton and to the keypad’s
REX wire (violet/ E6) and COM (black wires) terminals.
Solid State Outputs
The two solid state outputs (Outputs #3 & #4) can be programmed to
activate during various conditions. These “open collector” outputs can be
used to activate indicators or sounders. See fig. 5 for wiring examples
using the solid state outputs.
