Keypad Wiring
See Figure 7 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. A magnetic
switch is mounted on the 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 Figure 8 to assist in the wiring.
☞
NOTE:
Up to 500 feet of 18 AWG wire can be run for power,
use larger wire for longer runs. Use 22 AWG or larger
(depending on the load) for other connections.
OUTPUT
❑
Install a low voltage electric door strike for unlocking the
door.
❑
Route two wires between the door strike and the keypad
box. Connect one of the door strike wires to the keypad’s
MAIN RELAY N.O.
terminal (TB2 #3). Connect the other
door strike wire to the keypad’s
AC/DC +
terminal (TB2 #1).
Connect a wire between the keypad’s
AC/DC -
terminal
(TB2 #2) and the
MAIN RELAY COM
terminal (TB2 #4).
POWER
❑
Choose a location for the power supply or transformer.
❑
Route two wires between the power supply and the keypad
box. Connect the power supply’s output terminals to the
keypad’s
AC/DC
input terminals (TB2 #1 & #2). Observe
wiring polarity if using DC.
✦
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, connect
the
EARTH GROUND
terminal (TB1 #5) to a good earth
grounding point. Suggested wiring size is 18 AWG for earth
ground.
SENSE INPUT
☞
NOTE:
SENSE
terminal (TB1
#8) can be programmed for
either a door sense or inhibit input. Both features cannot be
used at the same time.
❑
To use the door sense feature to 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 box.
Connect the door switch to the keypad’s
SENSE
terminal
(TB1 #8) and
COM
terminal (TB1 #7).
❑
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 box. Connect the inhibit
switch/timer
normally open
terminals to the keypad’s
SENSE
(TB1 #8) and
COM
(TB1 #7) terminals.
REQUEST-TO-EXIT INPUT (wiring shown on Page 1, Figure 2)
❑
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
EXIT
(TB1 #6) and
COM
(TB1 #7) terminals.
Solid State Outputs
The two solid state outputs (Output #3 & Output #4) can be
programmed to activate during various conditions. These outputs
can be used to activate indicators or sounders. See Figure 9 for
wiring examples using the solid state outputs.
